Bringing In Backup

Today's Image of the Day from the European Space Agency features a satellite view of the fires burning in Southern California.



“Five wildfires - the biggest of which are the Palisades and the Eaton fires - are still currently burning (as of January 10, 2025) in areas of north Los Angeles. At least 10 people are known to have lost their lives and many more properties have been burnt to the ground,” said <a href="https://www.esa.int/ESA_Multimedia/Images/2025/01/Los_Angeles_struggles_to_contain_wildfires" target="_blank" rel="noreferrer noopener">ESA</a>.



“This image, captured by the Copernicus Sentinel-3 mission on January 9, 2025, shows the Palisades fire at lower left and the Eaton fire at upper right, with smoke seen reaching Catalina Island and the Santa Barbara reserve to the south of the fire.”&nbsp;



The fires have now burned more than 37,000 acres - an area bigger than San Francisco - according to Cal Fire. More than 12,000 structures have been destroyed.



<h2 class="wp-block-heading" id="h-tens-of-thousands-of-residents-displaced-by-fires">Tens of thousands of residents displaced by fires</h2>



The Palisades Fire is the largest at more than 21,000 acres, while the Eaton Fire has burned more than 14,000 acres. Those blazes are 11 percent and 15 percent contained, respectively.



Evacuation orders have displaced over 150,000 residents, with an additional 166,000 on alert. Temporary shelters are operating at full capacity, and widespread power outages have affected nearly 1.6 million homes.&nbsp;



<h2 class="wp-block-heading" id="h-strong-winds-and-a-lack-of-resources-nbsp">Strong winds and a lack of resources&nbsp;</h2>



Firefighting efforts are being hampered by strong <a href="https://www.earth.com/news/wildfire-smoke-is-more-toxic-than-other-sources-of-pollution/" target="_blank" rel="noreferrer noopener">winds</a>, with gusts reaching up to 100 miles per hour, and a lack of resources. Some fire hydrants have run dry, complicating containment efforts.&nbsp;



In response to the crisis, President Biden has approved federal disaster assistance, and additional firefighters from neighboring states are joining the efforts.&nbsp;



The California National Guard has been deployed, and the Department of Defense is providing personnel and equipment. Despite these measures, the fires continue to pose a significant threat to the region.&nbsp;



<h2 class="wp-block-heading" id="h-new-threats-from-the-palisades-fire-nbsp">New threats from the Palisades Fire&nbsp;</h2>



The Palisades Fire, which began near the Pacific Palisades neighborhood in Los Angeles, has rapidly expanded, prompting new evacuation orders for areas including Tarzana and Encino in the San Fernando Valley.&nbsp;



The fire's swift progression has been exacerbated by strong winds, causing it to grow by "three football fields of land per minute." This rapid expansion has led to mandatory evacuations along sections of the Pacific Coast Highway and surrounding areas.&nbsp;



The Los Angeles Fire Department reported that more than 10,000 houses and 13,000 buildings are under threat.&nbsp;



<h2 class="wp-block-heading" id="h-unpredictable-behavior-of-the-fires">Unpredictable behavior of the fires</h2>



In response to the advancing flames, evacuation orders were extended into Tarzana and Encino on January 10. Residents in these areas have been advised to evacuate promptly due to the fire's unpredictable behavior and the potential for further spread.&nbsp;



The situation remains critical, with firefighting efforts ongoing to contain the blaze and protect threatened communities.&nbsp;



Authorities continue to monitor the fire's progression and are urging residents to stay informed and adhere to evacuation orders for their safety.



<h2 class="wp-block-heading" id="h-wildfires-in-southern-california-nbsp">Wildfires in Southern California&nbsp;</h2>



<a href="https://www.earth.com/news/dry-lightning-sparks-the-most-destructive-california-wildfires/" target="_blank" rel="noreferrer noopener">Wildfires</a> in Southern California are particularly severe due to a combination of factors. The region’s hot, dry climate creates ideal conditions for fires, especially during the summer and fall when vegetation is parched.&nbsp;



Seasonal Santa Ana winds exacerbate the problem by driving <a href="https://www.earth.com/news/canadian-wildfires-of-2023-were-a-global-environmental-setback/" target="_blank" rel="noreferrer noopener">flames</a> rapidly across the landscape, making fires difficult to contain. The area’s diverse and often dense vegetation, such as chaparral and grasslands, provides abundant fuel.&nbsp;



Furthermore, Southern California’s growing urban footprint increases the risk of fires igniting due to human activity, while also placing more people and infrastructure in harm’s way.&nbsp;



Climate change intensifies these challenges by extending fire seasons and increasing the frequency of extreme heat and drought events, creating a feedback loop that makes wildfires increasingly <a href="https://www.earth.com/news/californias-forests-are-losing-their-ability-to-recover/" target="_blank" rel="noreferrer noopener">destructive</a>.



<h2 class="wp-block-heading" id="h-impacts-of-the-california-fires">Impacts of the California fires</h2>



The Palisades and Eaton Fires are among the most destructive wildfires in California's history, both in terms of structures destroyed and economic impact. Fortunately, however, they have not surpassed the Camp Fire in terms of human fatalities.



The Camp Fire of 2018 remains the deadliest wildfire in the state of California, with 85 fatalities. 



The financial impact of the current fires is unprecedented. Estimates suggest that the damages could reach between $135 billion and $150 billion, potentially making these wildfires the costliest in U.S. history.

Satellite captures devastating fires in Southern California

Today's Image of the Day from the European Space Agency...

Today's Image of the Day from NASA Earth Observatory features an astronaut view of Mount Nemrut, a volcano located in eastern Turkey near Lake Van.



Mount Nemrut is notable for its immense caldera, which was formed through a series of <a href="https://www.earth.com/news/volcanic-eruptions-play-an-overlooked-role-in-earths-climate/" target="_blank" rel="noreferrer noopener">eruptions</a>. The caldera, one of the largest in the world, now contains several lakes such as Lake Nemrut.&nbsp;



"The eastern half of the caldera is partially filled by solidified lava flows from past eruptions. Snow cover present at the time of this photo accentuates pressure ridges that formed as the lava was flowing and cooling," noted <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.



"These pressure ridges vary in size, thickness, and orientation due to the varying viscosity and flow direction of the lavas during eruptions."



<h2 class="wp-block-heading" id="h-formation-of-lake-nemrut">Formation of Lake Nemrut</h2>



"Lake Nemrut (Nemrut Gölü) occupies the western half of the caldera, creating a rough crescent shape that partially submerges the old lava flows," said NASA.



"This freshwater lake, reaching up to 176 meters deep, is accompanied by a smaller lake at the upper-center of the caldera."



The lake was formed after the collapse of the Nemrut volcano's summit. This collapse created a massive crater, which gradually filled with water over time, forming the <a href="https://www.earth.com/news/alarming-study-most-of-the-worlds-largest-lakes-are-quickly-losing-water/" target="_blank" rel="noreferrer noopener">lake</a>.



<h2 class="wp-block-heading" id="h-unesco-world-heritage-site">UNESCO World Heritage Site </h2>



Mount Nemrut and its surroundings are part of a protected UNESCO World Heritage Site due to their ecological and geological significance.



The site is home to diverse wildlife, including various bird species that use the lake as a stopover during migration. The caldera also contains smaller lakes and wetlands, adding to the area's biodiversity.



Lake Nemrut is a popular destination for tourists, hikers, and nature enthusiasts, offering stunning views of the volcanic landscape.



Despite its popularity, the lake remains relatively remote and unspoiled, contributing to its appeal as a natural wonder.



<h2 class="wp-block-heading" id="h-mount-nemrut-has-shaped-the-landscape">Mount Nemrut has shaped the landscape</h2>



Geologically, Mount Nemrut is interesting because its <a href="https://www.earth.com/news/new-research-enhances-predictions-on-volcanic-eruptions/" target="_blank" rel="noreferrer noopener">eruptions</a> have played a key role in shaping the local landscape. 



Its last major eruption occurred around 1441 AD, which indicates that it's not currently active but is considered dormant.



The area around Nemrut is known for its geothermal activity, including hot springs and fumaroles, suggesting that there is still significant heat beneath the surface.



Over thousands of years, various civilizations have inhabited the region around Nemrut, leaving behind a wealth of archaeological sites.



<h2 class="wp-block-heading" id="h-tribute-to-a-king">Tribute to a king</h2>



The summit of Mount Nemrut is dominated by a vast funerary mound constructed by King Antiochus I Theos, who ruled the Kingdom of Commagene in the 1st century BCE. 



The site was intended to serve as his tomb sanctuary and a place to commemorate the king's vision of divine kingship and unity between Eastern and Western cultures.



The mound, made of loose crushed stones, measures about 50 meters (164 feet) in height and spans a diameter of 150 meters (492 feet), creating an imposing feature visible from afar.



Surrounding the mound are terraces on the eastern, western, and northern sides, each adorned with colossal statues and reliefs. The statues, ranging in height from 8 to 10 meters (26 to 33 feet), represent various deities, including Zeus, Apollo, Hercules, and the goddess Tyche, alongside King Antiochus himself. 



The heads of the statues, many of which have toppled over due to <a href="https://www.earth.com/news/new-map-shows-75-percent-of-the-u-s-at-risk-of-damaging-earthquakes/" target="_blank" rel="noreferrer noopener">earthquakes</a> and erosion, lie scattered around the site, creating an iconic and enigmatic scene.



<h2 class="wp-block-heading" id="h-spiritual-and-religious-practices">Spiritual and religious practices</h2>



In addition to the statues, inscriptions at Mount Nemrut provide valuable historical information about the kingdom, the king's lineage, and the religious practices of the time.



The site is not only a marvel of ancient engineering but also a spiritual and astronomical center. Scholars believe the terraces were aligned with celestial events, serving as an observatory for solstices and equinoxes.



In addition to its natural and historical significance, the Nemrut volcano has been the subject of scientific study, as researchers aim to understand more about <a href="https://www.earth.com/news/volcanic-eruptions-play-an-overlooked-role-in-earths-climate/" target="_blank" rel="noreferrer noopener">volcanic activity</a> in the region, the history of its eruptions, and the potential risks it may pose in the future.

Mount Nemrut: Ancient mysteries and natural marvels 

Today's Image of the Day from NASA Earth Observatory features...

Today's Image of the Day from the European Space Agency features the galaxy I Zwicky 18, which was captured in remarkable detail by the James Webb Space Telescope.



I Zwicky 18 is a blue compact dwarf <a href="https://www.earth.com/news/newly-discovered-stars-milky-way-are-old-as-universe/" target="_blank" rel="noreferrer noopener">galaxy</a> located approximately 59 million light-years away in the constellation Ursa Major.&nbsp;



<h2 class="wp-block-heading" id="h-star-formation-in-i-zwicky-18">Star formation in I Zwicky 18</h2>



The galaxy is notable for its relatively young appearance and the fact that it contains very few heavy elements. These characteristics indicate that it has experienced little <a href="https://www.earth.com/news/baby-stars-release-sneezes-of-gas-and-dust-as-they-develop/" target="_blank" rel="noreferrer noopener">star formation</a> compared to other galaxies of similar age.



“The galaxy was first identified by Swiss astronomer Fritz Zwicky in the 1930’s and resides roughly 59 million light-years from Earth,” noted <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>. “This galaxy has gone through several sudden bursts of star formation.”&nbsp;



According to ESA, I Zwicky 18 is typical of the kinds of galaxies that inhabited the early universe and is much smaller than our <a href="https://www.earth.com/news/runaway-star-j1249-36-spotted-trying-to-escape-our-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">Milky Way</a>.



<h2 class="wp-block-heading" id="h-webb-telescope-image-of-the-galaxy">Webb telescope image of the galaxy</h2>



“Two major starburst regions are embedded in the heart of the galaxy. The wispy brown filaments surrounding the central starburst region are bubbles of gas that have been heated by stellar winds and intense ultraviolet radiation unleashed by hot, young stars,” said ESA.



“A companion galaxy resides nearby to the dwarf galaxy, which can be seen at the bottom of the wider-field image. The companion may be interacting with the dwarf galaxy and may have triggered that galaxy's recent star formation.”&nbsp;



ESA explained that the “orange blobs” surrounding the galaxy are the dim glow from ancient fully formed galaxies at much larger distances.



<h2 class="wp-block-heading" id="h-key-characteristics-of-i-zwicky-18">Key characteristics of I Zwicky 18</h2>



As previously mentioned, the galaxy has a very low abundance of elements heavier than hydrogen and helium, suggesting that it has not undergone significant stellar processing.



<h3 class="wp-block-heading" id="h-young-stellar-population-nbsp">Young stellar population&nbsp;</h3>



Despite its old age, I Zwicky 18 contains many young, hot stars. This suggests that it might have experienced a burst of <a href="https://www.earth.com/news/hubble-detects-awe-inspiring-newborn-star/" target="_blank" rel="noreferrer noopener">star formation</a> relatively recently in its history.



<h3 class="wp-block-heading" id="h-interstellar-medium-nbsp">Interstellar medium&nbsp;</h3>



The galaxy has a high density of gas, which is a prime ingredient for star formation. This gas is mostly in the form of hydrogen.



<h3 class="wp-block-heading" id="h-unusual-characteristics">Unusual characteristics</h3>



Its characteristics are more typical of primordial galaxies found in the early universe, making it a valuable object of study for understanding galaxy formation and evolution.



Ultimately, I Zwicky 18 provides insights into the conditions and processes that might have been prevalent in the early universe.



<h3 class="wp-block-heading" id="h-life-cycles-of-stars-and-dust">Life cycles of stars and dust</h3>



The image was captured as part of a Webb program to study the life cycle of dust in I Zw 18.&nbsp;



“Scientists are now building off of previous research with Hubble obtained at optical wavelengths, studying individual dusty stars in detail with Webb’s equivalent spatial resolution and sensitivity at infrared wavelengths.”&nbsp;



ESA noted that this galaxy is of particular interest as its content of elements heavier than helium is one of the lowest of all known <a href="https://www.earth.com/news/early-galaxy-formation-occurred-much-faster-than-we-thought/" target="_blank" rel="noreferrer noopener">galaxies</a> in the local universe.&nbsp;



“Such conditions are thought to be similar to those in some of the first star-forming galaxies at high redshift, so the Webb study of I Zw 18 should shed light on the life-cycle of stars and dust in the early universe.”



<h2 class="wp-block-heading" id="h-the-constellation-ursa-major">The constellation Ursa Major </h2>



Ursa Major, also known as the Great Bear, is one of the most prominent and easily recognizable constellations in the northern sky. 



Its name, "Ursa Major," means "Great Bear" in Latin, and it has been a significant part of various mythologies and star lore across cultures for thousands of years. 



One of the most famous asterisms within Ursa Major is the Big Dipper, a group of seven bright stars that form a shape resembling a ladle or dipper. The Big Dipper is often used as a navigation tool because it points to Polaris, the North Star, located in the nearby constellation Ursa Minor.



Ursa Major is best viewed in the northern hemisphere and is circumpolar, meaning it is visible year-round for much of the Northern Hemisphere. Its position changes with the seasons, rotating around Polaris, the North Star.

Dwarf galaxy provides a window into the early universe

Today's Image of the Day from the European Space Agency features massive amounts of smoke rising from multiple wildfires in Southern California&nbsp;



The largest blaze is the Palisades Fire, which ignited near the Pacific Palisades neighborhood in Los Angeles on January 7, 2025.&nbsp;



<h2 class="wp-block-heading" id="h-explosive-wildfire-conditions">Explosive wildfire conditions</h2>



The Palisades Fire spread rapidly due to severe drought conditions and strong Santa Ana winds, with gusts reaching up to 100 miles per hour.&nbsp;



Within hours, the fire expanded from 200 acres to over 2,900 acres, threatening thousands of structures and prompting mandatory evacuations for thousands of residents.



<h2 class="wp-block-heading" id="h-most-ferocious-winds-in-years">Most ferocious winds in years</h2>



A report from Fox Weather noted: “More than 260,000 people are under some sort of evacuation statement as multiple uncontained wildfires consume everything in their path.”



The news agency said that the fires are fueled by the “most ferocious Santa Ana winds in over 14 years.” The report further noted that “the level of destruction extends both north and south along the coast, with hurricane-force winds that are incredibly strong, dry, and unpredictable.”&nbsp;



As of January 8, the Palisades Fire had rapidly exploded to over 5,000 acres and remained uncontained. The cause of the fire is currently under investigation.&nbsp;



“This image captured by the Copernicus Sentinel-2 mission vividly depicts the smoke billowing from the fire near Santa Monica at 10:36 local time on January 7, 2025, not long after the fire broke out. The blaze has since caused widespread damage and concern,” noted <a href="https://www.esa.int/ESA_Multimedia/Images/2025/01/Los_Angeles_ablaze" target="_blank" rel="noreferrer noopener">ESA</a>.



<h2 class="wp-block-heading" id="h-widespread-damage-and-concern">Widespread damage and concern</h2>



The Los Angeles Fire Department (LAFD) has deployed over 1,400 firefighters to combat the blaze. However, the intense winds have hindered aerial firefighting efforts, as aircraft were grounded for safety reasons.&nbsp;



The fire has destroyed more than 1,000 structures, including several homes in Malibu, and has led to significant traffic congestion as residents evacuate the area.&nbsp;



<h2 class="wp-block-heading" id="h-warning-for-extreme-fire-behavior-nbsp">Warning for extreme fire behavior&nbsp;</h2>



On Monday, before the fires broke out, the weather service office in Los Angeles warned that wind gusts could reach 100 miles per hour in some areas this week - creating the potential for "extreme fire behavior.” 



In addition to the Palisades Fire, three other significant blazes include the Eaton Fire in the Altadena region and the Hurst Fire in northern Sylmar. These fires have prompted further evacuations and continue to threaten numerous structures.&nbsp;



"L.A. County and all 29 fire departments in our county are not prepared for this type of widespread disaster," LA County Fire Chief Anthony C. Marrone said at a news conference. "There are not enough firefighters in L.A. County to address four separate fires of this magnitude."



<h2 class="wp-block-heading" id="h-a-hurricane-of-fire">A hurricane of fire</h2>



High wind warnings and red flag warnings in effect across the region indicate that the critical fire weather conditions are ongoing.&nbsp;



Residents are advised to remain vigilant, adhere to evacuation orders, and stay informed through official channels as the situation evolves.



"Winds will not die down much until noon on Wednesday around Los Angeles," said meteorologist Ryan Maue on X. "The worst is yet to come in next few hours with 80-105 mph gusts. This is a hurricane of fire."



<h2 class="wp-block-heading" id="h-wildfires-in-southern-california-nbsp">Wildfires in Southern California&nbsp;</h2>



Wildfires in Southern California are particularly severe due to a combination of factors. The region’s hot, dry climate creates ideal conditions for fires, especially during the summer and fall when vegetation is parched.&nbsp;



Seasonal Santa Ana winds exacerbate the problem by driving flames rapidly across the landscape, making fires difficult to contain. The area's diverse and often dense vegetation, such as chaparral and grasslands, provides abundant fuel.&nbsp;



Furthermore, Southern California’s growing urban footprint increases the risk of fires igniting due to human activity, while also placing more people and infrastructure in harm’s way.&nbsp;



Climate change intensifies these challenges by extending fire seasons and increasing the frequency of extreme heat and drought events, creating a feedback loop that makes wildfires increasingly destructive.

Explosive wildfires in California fueled by hurricane-force winds

Today's Image of the Day from NASA Earth Observatory features a 9.5-mile section of Pangong Lake on the western end of the Tibetan Plateau. The image was captured by a crew member onboard the International Space Station. 



“In this winter scene, a sheet of cracked ice tops part of the lake,” noted <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>. “On the left side, open water appears blue. Shallow water offshore of a delta, formed by a small, winding river, appears green."



"Parallel lines along the coastlines of bays are visible in the high-resolution version of this image. These lines indicate raised beaches, which formed in the past when lake levels were higher.”



NASA pointed out that several roads cut across the landscape, including one with switchbacks that ascends a steep slope. "These roads facilitate tourist travel from both India and China.”&nbsp;



<h2 class="wp-block-heading" id="h-migratory-birds-at-pangong-lake-nbsp">Migratory birds at Pangong Lake&nbsp;</h2>



Pangong Lake and its surroundings are home to numerous bird species, particularly <a href="https://www.earth.com/news/migratory-birds-burn-unexpected-amounts-of-protein/" target="_blank" rel="noreferrer noopener">migratory birds</a>. Visitors can spot various waterfowl and waders that are rarely seen elsewhere.



“During the summer, species such as bar-headed geese and Brahminy ducks attract bird watchers to the lake, which is a major breeding ground for migrating birds,” said NASA.



Pangong Lake is one of the few places in India where the endangered black-necked crane is found during its breeding season. 



Ruddy shelduck and brown-headed <a href="https://www.earth.com/news/gulls-are-shifting-their-habitats-to-urban-areas/" target="_blank" rel="noreferrer noopener">gulls</a> are also frequently spotted around the lake. The ruddy shelduck is known for its striking orange-brown body and creamy white head, while the brown-headed gulls are often seen flying or swimming in the lake.



<h2 class="wp-block-heading" id="h-pangong-lake-nbsp">Pangong Lake&nbsp;</h2>



Pangong Lake is a stunning high-altitude lake situated in the <a href="https://www.earth.com/news/temperatures-are-rising-unexpectedly-fast-on-the-tibetan-plateau/" target="_blank" rel="noreferrer noopener">Himalayas</a>, extending from India to the Tibetan Autonomous Region of China. It is renowned for its mesmerizing beauty and dramatic setting, with the lake lying at an elevation of about 4,350 meters.



One of the most distinctive features of Pangong Lake is its changing colors, ranging from shades of blue to green and even red, influenced by the sky's reflection and the lake's mineral content.



This saline water lake is approximately 134 kilometers long and 5 kilometers wide at its broadest point. Despite its considerable size, Pangong Lake is relatively shallow.&nbsp;



The lake gained additional popularity after being featured in several Indian films - most notably the Bollywood hit "3 Idiots." Its remote location requires a permit for visitors, especially due to its proximity to the Line of Actual Control between India and China.



Despite the geopolitical sensitivities surrounding its location, Pangong Lake remains a favorite among tourists for its unparalleled natural beauty and serene environment.



<h2 class="wp-block-heading" id="h-high-altitude-lakes">High-altitude lakes</h2>



High-altitude lakes are unique bodies of water found at elevations typically above 3,000 meters (about 10,000 feet) in mountain ranges like the <a href="https://www.earth.com/news/himalayan-glaciers-retreating-threat-is-much-worse-than-previously-believed/" target="_blank" rel="noreferrer noopener">Himalayas</a>, Andes, and Rockies. 



These lakes are formed either by glacial activity, where glaciers erode the earth to create depressions that fill with melted snow and rainwater, or when natural dams created by landslides or moraines trap water in valleys.



<h3 class="wp-block-heading" id="h-extreme-environments">Extreme environments</h3>



The conditions at high altitudes make these lakes distinct in several ways. The climate is typically colder and harsher, with significant temperature variations between day and night. 



This extreme environment affects both the physical characteristics of the <a href="https://www.earth.com/news/alarming-study-most-of-the-worlds-largest-lakes-are-quickly-losing-water/" target="_blank" rel="noreferrer noopener">lakes</a> and the types of ecosystems they support. For example, due to lower atmospheric pressure, the boiling point of water is reduced, which can affect the type of life that can survive in these regions.



<h3 class="wp-block-heading" id="h-critical-habitats">Critical habitats</h3>



Biologically, high-altitude lakes often have limited biodiversity because only certain types of plants and animals can tolerate the cold temperatures and lower oxygen levels in the water. 



Despite this, these lakes are crucial habitats for some unique species of fish, birds, and other wildlife. They also serve as important indicators of climate change, as variations in their water levels and temperatures can reflect environmental shifts.



<h3 class="wp-block-heading" id="h-significance-of-high-altitude-lakes">Significance of high-altitude lakes </h3>



Lakes at high altitudes are often clear and pristine, due to the low density of human populations in these areas and minimal industrial activity, making them significant for ecological studies and attractive for tourism. 



However, they are sensitive ecosystems, and increased tourist activity brings challenges like pollution and habitat disruption.



High-altitude lakes are not only beautiful and scientifically significant but also hold cultural importance for local communities, often considered sacred and associated with historical and spiritual significance.

Pangong Lake on the Tibetan Plateau

Today's Image of the Day from NASA Earth Observatory features Ksudach, a remarkable volcanic complex located on Russia's Kamchatka Peninsula.



“The peninsula is one of the world’s most active volcanic arcs due to tectonic plate movement, with the Pacific Plate subducting under the Eurasian Plate,” noted <a href="https://earthobservatory.nasa.gov/images/153779/ksudachs-nested-calderas-and-craters" target="_blank" rel="noreferrer noopener">NASA</a>.



<h2 class="wp-block-heading" id="h-explosive-eruptions-of-ksudach">Explosive eruptions of Ksudach</h2>



Ksudach is classified as a shield <a href="https://www.earth.com/news/new-camera-helps-scientists-forecast-volcanic-eruptions/" target="_blank" rel="noreferrer noopener">volcano</a> due to the gentle slopes formed by its extensive lava flows. The combination of its shield-like structure and the prominent caldera system makes Ksudach a unique volcanic feature on the Kamchatka Peninsula.



“Several overlapping calderas and craters comprise the volcano. Calderas are large, bowl-shaped depressions created by the collapse of overlying material into an emptied subsurface magma chamber,” explained NASA.



“Craters are circular depressions created by volcanic activity, surface impacts, or explosions.”



This volcanic system has a fascinating geological history shaped by multiple explosive eruptions.&nbsp;



The most significant of these occurred around 240 AD, leaving behind a prominent caldera that now hosts scenic crater lakes, such as Lake Ksudach. 



“Lakes within the volcanic region are primarily recharged by rain and snowmelt from the winter season. This photo shows the water’s contrasting blue hues surrounded by green vegetation,” noted NASA.



“Traces of snow fill valleys within and outside the volcano’s caldera complex. These snow-covered areas highlight the drainage patterns from higher to lower elevations. Water that flows through these erosional pathways and into the caldera supports its vegetation and lakes.”



<h2 class="wp-block-heading" id="h-unique-landscape-of-ksudach-nbsp">Unique landscape of Ksudach&nbsp;</h2>



Ksudach's landscape also features pyroclastic deposits, lava flows, and hydrothermal features like fumaroles.&nbsp;



The surrounding environment - which is part of the UNESCO-listed Kamchatka Volcanoes - supports a diverse ecosystem with unique wildlife. 



Despite its remote location, Ksudach has drawn the attention of geologists, offering insights into <a href="https://www.earth.com/news/underwater-volcanic-eruptions-are-more-harmful-than-previously-believed/" target="_blank" rel="noreferrer noopener">volcanic processes</a> and the dynamics of caldera formation.



<h2 class="wp-block-heading" id="h-dynamic-nature-of-earth-s-geology-nbsp">Dynamic nature of Earth's geology&nbsp;</h2>



The most well-documented eruption of Ksudach occurred in March 1907. This eruption ranks as one of the largest in Kamchatka in the 20th century, with a Volcanic Explosivity Index (VEI) of 5.



The eruption produced a colossal ash column that soared into the stratosphere, dispersing fine particles over vast distances and contributing to global atmospheric changes.&nbsp;



The sheer force of the <a href="https://www.earth.com/news/icelands-volcanic-eruptions-may-continue-for-decades/" target="_blank" rel="noreferrer noopener">eruption</a> unleashed pyroclastic flows - fast-moving avalanches of hot gas, ash, and volcanic debris - that raced down the volcano's slopes, obliterating everything in their path.&nbsp;



These flows, capable of reaching temperatures over 1,000°C, decimated vegetation and altered the topography of the surrounding region.&nbsp;



Simultaneously, tephra deposits blanketed the landscape in layers of thick volcanic material, smothering ecosystems and creating a barren wasteland.&nbsp;



Today, Ksudach is considered an active <a href="https://www.earth.com/news/axial-seamount-large-underwater-volcano-off-us-coast-will-likely-erupt-in-2025/" target="_blank" rel="noreferrer noopener">volcano</a> but remains dormant. The region is closely monitored due to its potential for renewed <a href="https://www.earth.com/news/new-research-enhances-predictions-on-volcanic-eruptions/" target="_blank" rel="noreferrer noopener">activity</a>.



<h2 class="wp-block-heading" id="h-pacific-ring-of-fire-nbsp">Pacific Ring of Fire&nbsp;</h2>



The Kamchatka Peninsula lies along the Pacific Ring of Fire, a horseshoe-shaped zone encircling the Pacific Ocean where tectonic activity is highly concentrated.&nbsp;



This geologically dynamic area features numerous volcanoes, hot springs, geysers, and frequent seismic activity - making it a hotspot for both natural beauty and scientific study. 



Kamchatka is home to over 160 volcanoes, with about 30 considered active, including Klyuchevskaya Sopka, the highest and one of the most active in the region.



<h3 class="wp-block-heading" id="h-volcanic-activity-nbsp">Volcanic activity&nbsp;</h3>



As the Pacific Plate dives into the Earth's mantle, it melts and generates magma that feeds Kamchatka’s volcanic systems.&nbsp;



This ongoing tectonic interaction also contributes to the broader activity of the Pacific Ring of Fire, which accounts for approximately 75% of the world's active and dormant <a href="https://www.earth.com/news/supervolcano-italy-solfatara-crater-phlegraean-fields-shows-signs-of-waking-up/" target="_blank" rel="noreferrer noopener">volcanoes</a> and about 90% of its earthquakes.



<h3 class="wp-block-heading" id="h-broader-significance-nbsp">Broader significance&nbsp;</h3>



Beyond its geological significance, the Kamchatka Peninsula boasts a diverse ecosystem that is home to animals such as snow sheep, brown bears, red foxes, and unique plants that are adapted to its harsh environment. 



The coastal waters surrounding the peninsula support various fish species, including abundant salmon, as well as sea lions and killer whales.



The interplay of volcanic landscapes and pristine wilderness makes it a natural laboratory for understanding Earth's dynamic processes.

Ksudach: A volcano shaped by explosive forces

Today's Image of the Day from NASA Earth Observatory features an astronaut view of the Aladaghlar Mountains in northwestern Iran.



These <a href="https://www.earth.com/news/how-and-why-do-mountains-form-new-theories-for-an-age-old-mystery/" target="_blank" rel="noreferrer noopener">mountains</a> are known for their strikingly colorful landscapes, which make them stand out among other mountain ranges.



<h2 class="wp-block-heading" id="h-landscape-of-the-aladaghlar-mountains">Landscape of the Aladaghlar Mountains</h2>



"Ridges cast shadows in the valleys and other low elevation areas, creating a three-dimensional appearance. Human alterations to the landscape are most evident in riverbeds, where the even topography is easier to build on and navigate," said <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.



"Natural processes over millions of years have folded rock layers of various compositions and colors into the curved patterns seen here. These folds are produced by tectonic forces operating along the convergent plate boundary of the Arabia and Eurasia plates." 



<h2 class="wp-block-heading" id="h-the-rainbow-mountains">The Rainbow Mountains</h2>



One of the most remarkable features of the Aladaghlar Mountains is the vivid coloration of their slopes. 



The name "Aladaghlar" translates to "colorful mountains," which is a testament to their unique appearance.&nbsp;They are also known as the Rainbow Mountains.



<h2 class="wp-block-heading" id="h-wildlife-of-the-aladaghlar-mountains">Wildlife of the Aladaghlar Mountains </h2>



The Aladaghlar Mountains are part of a larger <a href="https://www.earth.com/news/mountain-ecosystems-are-in-urgent-need-of-protection/" target="_blank" rel="noreferrer noopener">ecosystem</a> that includes forests, meadows, and rivers, contributing to a rich biodiversity. 



The region supports a variety of wildlife, including several species that are unique to the area. The diverse wildlife add to the natural beauty and ecological importance of these <a href="https://www.earth.com/news/how-and-why-do-mountains-form-new-theories-for-an-age-old-mystery/" target="_blank" rel="noreferrer noopener">mountains</a>.



Among the larger mammals, the mountains host species such as brown bears, Persian leopards, and wild goats. The Aladaghlar Mountains also support smaller mammals, including foxes, hares, and various rodent species.&nbsp;



<a href="https://www.earth.com/news/how-mountains-influence-bird-evolution/" target="_blank" rel="noreferrer noopener">Birdlife</a> is abundant, including eagles, falcons, and a variety of songbirds. Reptiles like lizards and snakes are commonly found in the more humid areas, as well as amphibians.&nbsp;



<h2 class="wp-block-heading" id="h-cultural-significance-of-the-region">Cultural significance of the region</h2>



In addition to their natural appeal, the Aladaghlar Mountains hold cultural significance. The region has a rich history, with evidence of ancient civilizations and historical sites. 



Local communities have their unique cultures and traditions, which have been influenced by the natural environment of the mountains.



<h2 class="wp-block-heading" id="h-geology-of-the-aladaghlar-mountains-nbsp">Geology of the Aladaghlar Mountains&nbsp;</h2>



The geological history of these <a href="https://www.earth.com/news/mountains-both-carbon-sinks-and-carbon-sources/" target="_blank" rel="noreferrer noopener">mountains</a> is a fascinating tale of millions of years of natural processes.



The Aladaghlar Mountains are primarily composed of sedimentary rocks that have accumulated over millions of years. These sediments include sandstones, siltstones, shales, and conglomerates.



<h3 class="wp-block-heading" id="h-mineral-deposition-nbsp">Mineral deposition&nbsp;</h3>



The varying colors of the Aladaghlar Mountains are largely due to the presence of different minerals in the sedimentary layers. For example, red and orange hues are typically due to iron oxides, while greens can result from copper compounds.



These minerals were deposited in the sedimentary rocks through processes such as chemical precipitation, biological activity, and the weathering of parent rocks.



<h3 class="wp-block-heading" id="h-tectonic-activity">Tectonic activity</h3>



The region has experienced significant tectonic activity due to its location near the convergent boundary between the Arabian and Eurasian plates. This tectonic activity has caused the uplift and folding of the sedimentary layers, creating the mountain range.



The compression and folding associated with tectonic movements have also contributed to the exposure of the colorful strata that were originally deposited horizontally.



<h3 class="wp-block-heading" id="h-erosion-and-weathering">Erosion and weathering</h3>



Over time, erosion and weathering processes have played a crucial role in shaping the Aladaghlar Mountains. 



Wind, water, and temperature variations have eroded the softer rock layers more quickly than the harder ones, creating the distinctive ridges and valleys seen today.



These erosive processes have also helped to expose the underlying layers, revealing the vibrant colors and intricate patterns that attract tourists and geologists alike.



<h2 class="wp-block-heading">Tales and legends</h2>



One of the most famous tales associated with the Aladaghlar Mountains is that of a hidden treasure buried deep within the mountains by an ancient Persian king.&nbsp;



According to legend, the treasure is guarded by mystical creatures and can only be found by someone pure of heart and brave enough to face the challenges of the mountain.



<h3 class="wp-block-heading">The shepherd and the fairy</h3>



Another local legend tells the story of a young shepherd who fell in love with a fairy he encountered in the Aladaghlar Mountains. The fairy granted the shepherd three wishes, but warned him that the wishes would come with consequences.&nbsp;



Despite the warning, the shepherd made his wishes, which ultimately led to his downfall, serving as a cautionary tale about the dangers of greed.



<h3 class="wp-block-heading">The healing springs</h3>



The Aladaghlar Mountains are also said to be home to a spring with magical healing properties. According to folklore, those who bathe in the spring or drink its water are cured of all ailments.&nbsp;



However, the location of the spring is a closely guarded secret, known only to a few wise elders in the nearby villages.



<h3 class="wp-block-heading">The spirit of the mountain&nbsp;</h3>



Some locals believe that the Aladaghlar Mountains are inhabited by a protective spirit, who watches over the land and its people.&nbsp;



This spirit is said to bring good fortune to those who respect the mountain and its natural beauty, but misfortune to those who exploit or harm it.

The Aladaghlar Mountains of northwestern Iran

Today's Image of the Day from NASA Earth Observatory features Klinaklini Glacier, located in the Coast Mountains of British Columbia, Canada.



Klinaklini Glacier is notable for its size and the role it plays in the regional environment. It is part of a larger system of glaciers and ice fields in the area, which are critical for their contribution to <a href="https://www.earth.com/news/satellites-reveal-a-sudden-drop-in-global-freshwater-levels/" target="_blank" rel="noreferrer noopener">freshwater</a> resources and their influence on local climate conditions.



<h2 class="wp-block-heading" id="h-klinaklini-glacier-and-climate-change">Klinaklini Glacier and climate change</h2>



Klinaklini is particularly interesting due to its dynamics and response to climate change. Like many <a href="https://www.earth.com/news/melting-glaciers-pose-great-threat-to-biodiversity-in-mountain-ranges/" target="_blank" rel="noreferrer noopener">glaciers</a> around the world, it is being closely monitored for changes in its size, flow, and overall health. 



Glaciers in the Coast Mountains, including Klinaklini, have been studied for their response to global warming, with many showing signs of retreat and reduced ice mass.



"Decades of satellite images of western Canada make it clear that the region’s glaciers are shrinking and that the rate of ice loss is accelerating," said <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.



"In 1984, there were 14,329 glaciers in British Columbia and Alberta that were large enough to detect with sensors on the Landsat 5 satellite."



"By 2020, nearly 8 percent of them - 1,141 glaciers - had shrunk so much that newer Landsat sensors could no longer distinguish them, according to research conducted by University of Northern British Columbia glaciologists Alexandre Bevington and Brian Menounos."



<h2 class="wp-block-heading" id="h-ecological-role-of-the-klinaklini-glacier">Ecological role of the Klinaklini Glacier </h2>



Klinaklini Glacier also plays a crucial role in the local ecosystem. It feeds into the Klinaklini River, which is an important waterway for the region. 



The river supports a variety of wildlife, including salmon populations that are vital both ecologically and economically for local communities.



Studies conducted on and around the Klinaklini Glacier contribute to the understanding of glaciology, <a href="https://www.earth.com/news/alpine-glaciers-will-lose-half-of-their-volume-by-2050/" target="_blank" rel="noreferrer noopener">climate change</a>, and hydrology. 



This research is essential for predicting future changes in the glacier and for understanding the broader impacts of climate change on glacial systems globally.



<h2 class="wp-block-heading" id="h-coast-mountains-of-british-columbia">Coast Mountains of British Columbia </h2>



The Coast Mountains of British Columbia are a striking and expansive mountain range forming part of the Pacific Coast Ranges in western North America. 



Stretching approximately 1,600 kilometers from the Fraser River near Vancouver in the south to the Yukon Territory in the north, the range is known for its rugged beauty and significant ecological and cultural importance.



<h3 class="wp-block-heading" id="h-geography-of-the-mountains">Geography of the mountains</h3>



Geographically, the Coast Mountains are positioned between the Pacific Ocean to the west and the Interior Plateau to the east.



They are divided into three main sections: the Pacific Ranges in the south, the Kitimat Ranges in the central region, and the Boundary Ranges in the north, which extend into Alaska and Yukon. 



<h3 class="wp-block-heading" id="h-geological-processes">Geological processes</h3>



The range's dramatic landscapes include steep peaks, fjords, and valleys carved by ancient <a href="https://www.earth.com/news/melting-glaciers-release-vast-quantities-of-unknown-microbes/" target="_blank" rel="noreferrer noopener">glaciers</a>, highlighting the lasting influence of glaciation on the region.



Geologically, the Coast Mountains are part of the Pacific Ring of Fire, formed by volcanic and tectonic activity. 



Their granitic composition is a result of millions of years of geological processes. Mount Waddington, the highest peak in the range at 4,019 meters, stands as a notable landmark in the Pacific Ranges.



<h3 class="wp-block-heading" id="h-climate-and-wildlife">Climate and wildlife</h3>



The climate of the Coast Mountains varies significantly depending on location. The western slopes are characterized by a temperate rainforest climate, with high levels of precipitation brought by moist Pacific air. 



In contrast, the eastern slopes are drier, with semi-arid conditions in some areas. This climatic diversity supports a wide range of ecosystems, from lush coastal rainforests to alpine tundra. 



The region is home to diverse <a href="https://www.earth.com/news/outdoor-recreation-noise-triggers-fear-response-in-wildlife/" target="_blank" rel="noreferrer noopener">wildlife</a>, including black bears, grizzly bears, mountain goats, and numerous bird species.



<h3 class="wp-block-heading" id="h-recreation-and-culture">Recreation and culture</h3>



The Coast Mountains are a popular destination for recreation and tourism. Activities such as hiking, skiing, snowboarding, and mountaineering draw visitors from around the world - particularly to destinations like Whistler, a renowned resort town in the Pacific Ranges. 



The fjords and valleys of the range provide opportunities for kayaking, fishing, and scenic exploration.



Indigenous peoples, including the Tlingit, Tsimshian, Haida, and Squamish, have lived in and around the Coast Mountains for millennia. 



These groups maintain a deep connection to the land, reflected in their stories, traditions, and art. The mountains are not only a physical presence but also a vital cultural and spiritual landscape.

Lake Erie /ˈɪəri/ (French: Lac Érié) is the fourth-largest lake (by surface area) of the five Great Lakes in North America, and the eleventh-largest globally if measured in terms of surface area.It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is 210 feet (64 metres) deep. 
Situated on the International Boundary between Canada and the United States, Lake Erie&#8217;s northern shore is the Canadian province of Ontario, specifically the Ontario Peninsula, with the U.S. states of Michigan, Ohio, Pennsylvania, and New York on its western, southern, and eastern shores. These jurisdictions divide the surface area of the lake with water boundaries. 
The lake was named by the Erie people, a Native American people who lived along its southern shore. The tribal name &#8220;erie&#8221; is a shortened form of the Iroquoian word erielhonan, meaning long tail

"Windows to the soul" - a phrase often used to describe the eyes - takes on new significance with a recent study. The research reveals that the pupil and iris, essential parts of the eye, play a crucial role in influencing how others perceive us.



The team behind this discovery was led by Juan Olvido Perea-Garcia at <a href="https://www.universiteitleiden.nl/en" target="_blank" rel="noreferrer noopener">Leiden University</a>. The researchers found that our eyes have a profound influence over how our attractiveness and generosity are perceived. 



It's not all about eye color, though. In fact, pupil size and iris brightness are pivotal contributors.



<h2 class="wp-block-heading" id="h-subtle-eye-features-shape-impressions">Subtle eye features shape impressions</h2>



While eye color is often the most noticeable feature of the eyes, this study focuses on two other important aspects:&nbsp;pupil size&nbsp;and&nbsp;iris brightness. 



These features, though less discussed, have a significant impact on how others perceive a person’s personality and appearance. 



The researchers discovered that larger pupils and brighter irises can make individuals appear friendlier, more attractive, and even influence the level of generosity they inspire in others. 



These subtle traits go beyond eye color in shaping <a href="https://www.earth.com/news/survival-of-the-friendliest-social-animals-live-longer/" target="_blank" rel="noreferrer noopener">social impressions</a> and emotional responses.



<h2 class="wp-block-heading" id="h-small-changes-in-eye-morphology">Small changes in eye morphology </h2>



In the study, participants looked at photos of non-human primates whose eyes had been digitally modified. Some images showed primates with brighter irises and larger pupils. 



These primates were consistently rated as more attractive and friendly compared to those with smaller pupils or less bright irises. 



Additionally, primates with larger pupils inspired participants to donate more money, highlighting how even small changes in eye appearance can influence human behavior.



“Our results demonstrate that small changes in perceived eye morphology impact behavior and affective responses,” the researchers explained.



<h2 class="wp-block-heading" id="h-larger-pupils-make-us-seem-friendlier">Larger pupils make us seem friendlier</h2>



The researchers conducted two experiments on irises and pupil size. In the first experiment, participants were shown photos of 32 different primate species. 



The researchers digitally adjusted the pupil sizes in these images, making some pupils larger and others smaller.



The results revealed that primates with&nbsp;larger pupils&nbsp;were consistently rated higher for qualities like cuteness, friendliness, and attractiveness. This showed that pupil size alone has a strong influence on how appealing or approachable the animals appeared.



<h2 class="wp-block-heading" id="h-bright-irises-and-large-pupils">Bright irises and large pupils</h2>



In the second experiment, the researchers examined the combined effects of&nbsp;iris brightness&nbsp;and&nbsp;pupil size. They modified both features in the images. 



The experts noted that bright irises enhanced the animals’ attractiveness and friendliness ratings, but only when the pupils were dilated (larger).



When paired with small pupils, the positive effects of bright irises were diminished. This highlighted the importance of the interaction between these two eye features in shaping perceptions.



These experiments demonstrate how subtle changes in eye appearance - like the size of the pupils and the brightness of the irises - can significantly impact how others perceive traits such as friendliness, cuteness, and attractiveness.



<h2 class="wp-block-heading" id="h-eye-features-and-emotional-responses">Eye features and emotional responses</h2>



The study’s findings uncover a fascinating <a href="https://www.earth.com/news/how-ai-could-protect-millions-of-people-from-vision-loss/" target="_blank" rel="noreferrer noopener">connection</a> between the physical features of eyes and the emotional responses they evoke.



According to the researchers, both cuteness and&nbsp;friendliness&nbsp;ratings closely followed the same trend, suggesting that&nbsp;pupil size&nbsp;plays the most significant role in shaping these perceptions.



When irises were&nbsp;bright, they made the animals appear much cuter - but only if their pupils were&nbsp;large&nbsp;(dilated).



Conversely, when the same bright irises were paired with&nbsp;constricted&nbsp;(smaller) pupils, the perceived cuteness dropped noticeably. This indicates that the combination of bright irises and large pupils creates the strongest positive emotional response.



On the other hand,&nbsp;dark irises, which tend to make it harder to distinguish pupil size, produced more neutral reactions. 



This suggests that the visibility of the pupil is crucial in influencing how others perceive traits like friendliness and cuteness. The findings emphasize how even small changes in eye morphology can significantly affect emotional and social judgments.



<h2 class="wp-block-heading" id="h-implications-for-humans">Implications for humans</h2>



Although this study was focused on non-human primates, its implications extend to humans. Our eyes play a pivotal role in social interactions, subtly shaping how others judge us.



Whether through a kind gaze or bright, welcoming irises, our eyes might convey more than we realize.



As science uncovers these hidden dynamics, it becomes clear that the eyes truly are a powerful tool for <a href="https://www.earth.com/news/people-with-power-are-more-likely-to-cheat-on-their-partners/" target="_blank" rel="noreferrer noopener">connection</a>.



The study is published in the journal&nbsp;<a class="" href="https://www.tandfonline.com/doi/full/10.1080/02699931.2024.2427340#abstract" target="_blank" rel="noreferrer noopener">Cognition and Emotion</a>.

Specific eye features influence how others perceive us

"Windows to the soul" - a phrase often used to...

In the intricate networks of human and animal brains, decision-making is a highly complex process. While chemical synapses often take center stage, it appears they're not the only stars of the show.



Recent research from scientists at Yale and the University of Connecticut has revealed the significant role of electrical synapses in shaping our decisions.



The study was led by Dr. Daniel Colon-Ramos, a professor of neuroscience and cell biology at Yale School of Medicine.



<h2 class="wp-block-heading" id="h-how-brains-make-decisions">How brains make decisions</h2>



Animal brains are like supercomputers that handle endless streams of information from the world around them - what they see, hear, <a href="https://www.earth.com/news/odors-prompt-brain-cells-to-make-decisions-before-you-know-whats-happening/" target="_blank" rel="noreferrer noopener">smell</a>, and sense. But not all of this information is important.



To make sense of it all, <a href="https://www.earth.com/news/how-the-brain-uses-context-to-make-complex-decisions/" target="_blank" rel="noreferrer noopener">brains use a system</a> to filter out irrelevant details (like background noise or unimportant sights) and focus only on the most critical information for the moment.



For example, a rabbit in a field might hear the wind rustling the grass (irrelevant) but will quickly focus on the sound of a predator approaching (critical). This ability to tune in to the most important details and act accordingly is what scientists call&nbsp;“action selection.”&nbsp;



It’s the brain’s way of <a href="https://www.earth.com/news/brain-cells-communicate-to-support-decision-making/" target="_blank" rel="noreferrer noopener">deciding</a> what to pay attention to and how to respond, helping animals survive and thrive in their environments.



“For animals, filtering sensory input is not about blocking noise but prioritizing context-relevant signals,” explained Daniel Colón-Ramos, Yale neuroscientist and senior author of the study.



<h2 class="wp-block-heading" id="h-adjusting-behavior-based-on-context">Adjusting behavior based on context</h2>



The study centered on a tiny worm called&nbsp;C. elegans, which might seem simple but offers powerful insights into <a href="https://www.earth.com/news/your-brain-literally-changes-based-on-daily-activities-and-lifestyle/" target="_blank" rel="noreferrer noopener">how brains work</a>. Despite its small size and basic nervous system,&nbsp;C. elegans&nbsp;shows surprisingly advanced behavior, such as choosing and sticking to its preferred temperature.



When placed in an environment with varying temperatures, these worms navigate toward their "ideal" temperature zone. They first use a strategy called&nbsp;gradient migration, moving across the temperature gradient until they get closer to their preferred range.



Once they arrive near their target temperature, the worms switch to a different strategy known as isothermal tracking. In this phase, they fine-tune their movements to stay within the ideal temperature zone, ensuring that they remain comfortable.



These two strategies highlight how even simple creatures can adjust their behavior based on context, making C. elegans an excellent model for studying decision-making and neural processes.



But how do they determine which behavior fits the context?



<h2 class="wp-block-heading" id="h-role-of-electrical-synapses">Role of electrical synapses</h2>



The researchers identified electrical synapses, mediated by a protein called INX-1, as key players. These synapses connect two neurons (AIY neurons) responsible for locomotion decisions. 



Unlike chemical synapses, electrical synapses act as filters, dampening weak signals and prioritizing significant sensory input.



“Altering this electrical conduit in a single pair of cells can change what the animal chooses to do,” Colón-Ramos said.



In worms with normal INX-1 function, the electrical synapses reduce sensitivity to minor temperature changes, allowing the worms to navigate efficiently. However, worms lacking INX-1 show hypersensitivity to small fluctuations, causing them to get “stuck” in less favorable conditions.



“It’s like watching a confused bird flying with its legs extended,” Colón-Ramos noted. “Birds normally extend their legs to land, but doing so mid-flight disrupts their goals.”



<h2 class="wp-block-heading" id="h-implications-for-broader-neuroscience">Implications for broader neuroscience</h2>



Electrical synapses exist <a href="https://www.earth.com/news/optimal-decision-making-is-a-balance-of-experience-and-knowledge/" target="_blank" rel="noreferrer noopener">across many species</a>, including humans, suggesting the findings have far-reaching implications. 



For example, similar configurations of electrical synapses in amacrine cells help regulate visual sensitivity in human retinas.



“These findings allow scientists to explore how single-neuron relationships influence perception and behavior,” said Colón-Ramos. “The principles of action selection may vary, but the role of electrical synapses in shaping sensory responses could be widespread.”

The study FROM Yale and <a href="https://uconn.edu" target="_blank" rel="noreferrer noopener">University of Connecticut</a> highlights the critical role of electrical synapses in guiding decision-making by filtering sensory information. 



By unraveling this mechanism in worms, scientists gain insights into broader principles of neuroscience, with potential applications in understanding human cognition and behavior.

Carbon storage in Earth’s deep seas continues to reveal surprising complexities, as scientists uncover more about the intricate processes of our oceans. 



These vast underwater ecosystems play a pivotal role in regulating our planet's climate, with microscopic organisms often driving major biogeochemical cycles. 



One such discovery comes from a recent study led by the <a href="https://noc.ac.uk/" target="_blank" rel="noreferrer noopener">UK's National Oceanography Centre</a> (NOC).



The research team offers a fresh perspective on the role that a unique group of microscopic algae play in carbon sequestration - the natural storage of carbon in the ocean.



<h2 class="wp-block-heading" id="h-carbon-storage-in-the-southern-ocean">Carbon storage in the Southern Ocean</h2>



Microscopic algae known as diatoms play a significant role in pulling carbon down into the deep ocean, particularly in the Southern Ocean, which holds about a third of the organic carbon stored in the world's oceans.



Diatoms carry distinct dense, silica-based structures that resemble petite glass houses. 



Scientists have long believed these structures provide enough weight - or ballast - for the diatoms to sink into deeper waters, dragging carbon along with them into the deep blue depths.



"The ocean plays a key role in the global <a href="https://www.earth.com/news/marine-plankton-are-key-players-in-carbon-cycle-regulation/" target="_blank" rel="noreferrer noopener">carbon cycle</a>, with tiny, microscopic plants taking up billions of tons of carbon from the atmosphere every year," said Dr. Sari Giering, Research Lead at NOC. 



"For years, it has been believed that this group of plankton - diatoms - play a crucial role in efficiently transporting carbon to the deep ocean, where it is held out of contact with the atmosphere."



<h2 class="wp-block-heading" id="h-reconsidering-the-biological-carbon-pump">Reconsidering the biological carbon pump</h2>



Diatoms and other types of phytoplankton absorb carbon near the sea surface. This process is part of what's known as the biological carbon pump - a series of processes that funnel this carbon to the deep ocean.



But according to recent findings from the NOC study, the diatom skeletons don't quite make the long descent. Instead, they linger near the surface, while carbon journeys to the deep ocean through other, yet unidentified means.



"We now understand that diatoms are not always contributing as heavily to the Southern Ocean’s carbon pump as we once thought," said Dr. Giering. "This means there are unknown or poorly measured processes happening in the deep ocean that we need to learn more about.”



<h2 class="wp-block-heading" id="h-the-future-of-ocean-carbon-storage">The future of ocean carbon storage</h2>



Scientists have been increasingly worried that ocean warming could impact diatom productivity and thus, reduce the effectiveness of the biological carbon pump in the <a href="https://www.earth.com/news/southern-ocean-absorbs-more-co2-than-previously-thought/" target="_blank" rel="noreferrer noopener">Southern Ocean</a>. 



However, this recent study suggests that these changes might not greatly impact the carbon storage capacity of the Southern Ocean.



“The Southern Ocean is vulnerable to <a href="https://www.earth.com/news/ocean-warming-will-likely-continue-for-centuries/" target="_blank" rel="noreferrer noopener">ocean warming</a>, which may alter the availability of nutrients and reduce diatom numbers in the future,” said Jack Williams, a post-graduate researcher at the University of Southampton. “But our results suggest these changes may not impact the strength of Southern Ocean carbon storage as much as previously thought."



Carbon continues to descend to the ocean's depth, which suggests that there are yet undiscovered processes occurring in the "twilight zone" of the ocean.



Unveiling these processes is crucial for accurately predicting how the oceans may store carbon in the future. 



<h2 class="wp-block-heading" id="h-the-twilight-zone-a-frontier-of-discovery">The twilight zone: A frontier of discovery</h2>



The twilight zone, a mid-ocean layer spanning depths of 100 to 1,000 meters, has emerged as a critical area of interest for scientists studying carbon storage. Despite its name, this zone is far from a lifeless void.



It hosts a dynamic ecosystem of organisms and complex processes that are only beginning to be understood. 



Recent findings suggest that much of the carbon transported into the deep ocean originates in this layer, bypassing the mechanisms traditionally associated with surface plankton like diatoms.



In this dimly lit zone, carbon is carried by sinking particles known as marine snow - aggregates of organic material, dead plankton, and other detritus. However, the exact processes enabling this descent remain elusive.



The twilight zone acts as a gatekeeper, determining how much carbon reaches the ocean depths. Understanding these pathways is vital for improving climate models and predicting how oceanic carbon storage will respond to global warming.



Ongoing research into the twilight zone could hold the key to unlocking the ocean's full carbon sequestration potential, providing insights that may redefine conservation strategies and our approach to mitigating climate change.

Carbon storage mystery emerges in the Southern Ocean

Carbon storage in Earth’s deep seas continues to reveal surprising...

Researchers have identified a fascinating six-planet system that offers a different take on planetary configurations. The newly <a href="https://www.nature.com/articles/s41586-023-06692-3" target="_blank" rel="noreferrer noopener">reported</a> configuration features six planets around a single star. Their orbits line up in a synchronized manner, which astronomers call resonance.



When <a href="https://www.earth.com/news/how-planets-form-its-much-more-complicated-than-we-thought/" target="_blank" rel="noreferrer noopener">planets</a> move in resonance, their orbital periods stay in a fixed ratio for millions or even billions of years. This pattern can be so exact that it reminds some observers of musical tempos. 



Spotting this kind of rhythmic harmony helps scientists figure out why some stars gather families of planets that have stood the test of time.



The analysis was led by <a href="https://astro.uchicago.edu/people/rafael-luque.php" target="_blank" rel="noreferrer noopener">Rafael Luque</a> from the University of Chicago.



<h2 class="wp-block-heading" id="h-rare-six-planet-system">Rare six-planet system</h2>



Known as HD110067, this star sits approximately 100 light-years away in the northern constellation of <a href="https://noirlab.edu/public/education/constellations/comaberenices/" target="_blank" rel="noreferrer noopener">Coma Berenices</a>.



Astronomers first recognized unusual dips in the star’s brightness when NASA’s Transiting Exoplanet Survey Satellite (<a href="https://science.nasa.gov/mission/tess/" target="_blank" rel="noreferrer noopener">TESS</a>) started surveying that region.&nbsp;



Each tiny dip hinted that one of the star’s planets was crossing its face. Data from both TESS and the European Space Agency’s CHaracterizing ExOPlanet Satellite (<a href="https://www.esa.int/Science_Exploration/Space_Science/Cheops" target="_blank" rel="noreferrer noopener">Cheops</a>) revealed something rare: a neat chain of six sub-Neptune planets in close orbits. 



“This discovery is going to become a <a href="https://www.earth.com/news/vega-star-system-discovery-forces-us-to-rethink-planet-formation/" target="_blank" rel="noreferrer noopener">benchmark system</a> to study how <a href="https://www.earth.com/news/neptune-like-exoplanets-atmospheres-interesting-earth-size-neighbors/" target="_blank" rel="noreferrer noopener">sub-Neptunes</a>, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the right conditions to support the existence of liquid water in their surfaces,” remarked Luque.



<h2 class="wp-block-heading" id="h-understanding-sub-neptunes">Understanding sub-Neptunes</h2>



Many stars in our galaxy hold at least one planet that’s bigger than Earth but smaller than Neptune. These in-between worlds are often called sub-Neptunes, and they’re more plentiful than massive gas giants like Jupiter. 



Scientists are intrigued by this <a href="https://www.earth.com/news/newborn-planet-is-still-glowing-from-the-heat-of-its-formation/" target="_blank" rel="noreferrer noopener">class of planet</a> because it covers a range of possible compositions. Some might hold thick, gas envelopes, while others could have dense, rocky surfaces.



Observing these in sync can show how these planets get locked in place and remain that way for an incredibly long span of time.



<h2 class="wp-block-heading" id="h-choreography-of-this-planetary-system">Choreography of this planetary system</h2>



Resonant systems form when <a href="https://www.earth.com/news/rare-six-planet-star-system-moves-in-strange-perfect-synchrony/" target="_blank" rel="noreferrer noopener">planets start out with orbits</a> that nudge each other in a balanced way. Small gravitational pulls set up a regular rhythm. But big objects or random gravitational jostling can break these patterns. 



That makes resonance a tricky arrangement to maintain. Astronomers <a href="https://www.nature.com/articles/s41586-023-06692-3" target="_blank" rel="noreferrer noopener">estimate</a> that only about one percent of multi-planet systems preserve this stable <a href="https://exoplanets.nasa.gov/news/1771/discovery-alert-watch-the-synchronized-dance-of-a-6-planet-system/" target="_blank" rel="noreferrer noopener">choreography</a>. 



Not all stars are lucky enough to keep their planetary brood free of turbulence. Some lose this delicate pattern when a larger planet barges in or when stars drift near one another.&nbsp;



The lack of large neighbors in HD110067’s environment might have helped these six sub-Neptunes remain nestled in their precise arrangement for so long.&nbsp;



Without any violent intrusions, the orbits can carry on as they have since formation. This level of cooperation in one system could provide hints about how others might form or break apart.



<h2 class="wp-block-heading" id="h-why-does-this-six-planet-system-matter">Why does this six-planet system matter?</h2>



For experts who study planet formation, every new system that shows a clear pattern provides more <a href="https://www.science.org/doi/10.1126/science.1194854" target="_blank" rel="noreferrer noopener">evidence</a> about how dust and gas swirl together and eventually become planets.



Some calculations suggest planets might typically start in resonance, but migration and collisions can make them drift. 



An untouched system paints a cleaner picture of early planet-building. Pinpointing each planet’s mass and density can also highlight the proportions of rocky materials, water, and gas they contain.



Researchers plan to keep a close eye on HD110067’s planets using more precise techniques. Improving measurements of the planets’ masses and densities will help astronomers to figure out what these sub-Neptunes look like on the inside.



Deeper analysis can also show whether any might have conditions that allow water to stick around on the surface. These tasks will probably involve instruments on large ground-based telescopes and future space observatories.



Astronomers hope the data from this oddly balanced system will reveal reasons why some worlds remain in tight-knit formation, while others never stabilize.



<h2 class="wp-block-heading" id="h-a-puzzle-worth-solving">A puzzle worth solving</h2>



Stumbling upon a collection of planets that circle in smooth synchronization gives a glimpse into the hidden patterns that <a href="https://www.earth.com/news/ancient-stars-shakti-shiva-shaped-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">shape the galaxy</a>.



This compact group orbiting HD110067 might be just one example of what sub-Neptunes can do when left undisturbed.&nbsp;



Folks who are fascinated by the way planetary families and planet systems form see this system as a chance to learn. 



It challenges scientists to look for other hidden resonances in our galaxy and sparks the question of how many have slipped past our detection.



The full research paper was published in the journal <a href="https://www.nature.com/articles/s41586-023-06692-3" target="_blank" rel="noreferrer noopener">Nature</a>.

NASA is examining ways to ensure explorers have nourishing produce, including fresh plants, on future space missions to the Moon and Mars. While sealed food packets get the job done, they can lose flavor and vitamins over time.



Cultivating leafy greens and vegetables on the space station could address this problem and give crews a happier mental state. 



Efforts to grow plants such as lettuce, peppers, radishes, and tomatoes in microgravity have been underway, revealing new insights into how spaceflight influences plant genetics, water use, and flavor.



<h2 class="wp-block-heading" id="h-plants-are-key-to-space-exploration">Plants are key to space exploration</h2>



This work is being guided by <a href="https://npp.orau.org/experiences/gioia-massa.html" target="_blank" rel="noreferrer noopener">Gioia Massa</a> from NASA. Her background involves studying plant behavior in space to help boost the <a href="https://www.earth.com/news/why-do-astronauts-meals-lose-flavor-in-space/" target="_blank" rel="noreferrer noopener">variety and taste</a> of fresh crops.&nbsp;



As NASA paves the path toward deeper space travel, her team has focused on how <a href="https://www.nasa.gov/learning-resources/for-kids-and-students/what-is-microgravity-grades-5-8" target="_blank" rel="noreferrer noopener">microgravity</a> and factors like humidity and light control affect plant shape, nutrient quality, and yield. 



By examining bacteria that live alongside the plants, they also track whether these microorganisms remain safe and beneficial for human health.



<h2 class="wp-block-heading" id="h-growing-crops-in-microgravity">Growing crops in microgravity</h2>



One key study, <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=9195" target="_blank" rel="noreferrer noopener">Plant Habitat-07</a>, looks at how lettuce tolerates different moisture conditions in microgravity. 



Although water is crucial for plant cells, too much can restrict oxygen at the roots, and too little can cause wilting.&nbsp;



This investigation uses four moisture scenarios in a specialized growth chamber to see how <a href="https://www.earth.com/news/space-tomatoes-are-ready-for-an-unprecedented-mission/" target="_blank" rel="noreferrer noopener">plants</a> adjust nutrient production. 



Researchers check yield, overall plant health, and whether bacterial populations on the leaves pose any risk. Early data point to the importance of balancing water to maintain robust leaves that still taste good.



<h2 class="wp-block-heading" id="h-making-space-grown-veggies-tastier">Making space-grown veggies tastier</h2>



NASA’s <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=7896" target="_blank" rel="noreferrer noopener">Veg-04A</a> and <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=7895" target="_blank" rel="noreferrer noopener">Veg-04B</a> explorations spotlighted how <a href="https://www.earth.com/news/electro-agriculture-grows-food-in-the-dark-with-94-less-land-required/" target="_blank" rel="noreferrer noopener">light quality</a> and fertilizer affect lettuce and leafy greens on station. 



Studies found that switching red and blue LEDs, or adjusting nutrient formulas, changes how the leaves look, taste, and grow.&nbsp;



These investigations guided more recent plantings of other crops, such as tomatoes. Crew members gave feedback on freshness and flavor, which could inform future seed selection for diverse salads during long-duration spaceflights.

Researchers tracked DNA methylation—a process that can switch genes on or off. 



Their discoveries open new avenues for customizing plant genes to handle the difficulties of space, like unusual water movement or limited floor space.



<h2 class="wp-block-heading" id="h-hormones-and-movement">Hormones and movement</h2>



Scientists have <a href="https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=1730" target="_blank" rel="noreferrer noopener">explored</a> how plant hormones guide growth in microgravity. One series of tests examined <a href="https://pubmed.ncbi.nlm.nih.gov/34396657/" target="_blank" rel="noreferrer noopener">auxins</a>, natural signals that steer root and shoot direction.&nbsp;



Some <a href="https://www.earth.com/news/grow-plants-on-moon-by-2026-nasa-artemis-iii-mission/" target="_blank" rel="noreferrer noopener">plant</a> species had lower auxin levels when floating in microgravity, which curbed their normal pattern of upward stem development. 



Others had higher levels, suggesting that the exact outcome varies by species. This subtle shift in plant chemistry helps NASA design growth chambers that best support each crop’s needs.



<h2 class="wp-block-heading" id="h-engineering-plants-to-handle-space">Engineering plants to handle space</h2>



Roots and shoots in microgravity can develop weaker supportive tissues or, in some cases, produce thicker walls for unknown reasons. 



An <a href="https://www.nature.com/articles/s41526-023-00312-0" target="_blank" rel="noreferrer noopener">investigation</a> used a suite of lab tools to identify changes in molecules that build plant cell walls, especially those providing mechanical strength.&nbsp;



Although some species quickly adapt and form healthy walls, others remain frail. NASA’s next step is to refine which varieties flourish with minimal gravity or to tweak conditions so roots are less prone to bending or thinning.



<h2 class="wp-block-heading" id="h-sterols-and-space-based-flowering">Sterols and space-based flowering</h2>

Sterols help keep cell membranes stable and support a range of growth responses, including when and how a plant transitions to flowering. 



The drop in sterols in microgravity can slow certain steps in development. By noting which genes control those sterols, scientists may spot ways to keep plants on schedule.



<h2 class="wp-block-heading" id="h-preparing-for-space-missions-with-plants">Preparing for space missions with plants</h2>



Having tasty salad greens aboard the station is only the first step. NASA’s focus is on sustaining crews through missions lasting many months. 



The progress so far is encouraging: fresh produce is feasible in orbit, and each new finding helps refine the process.&nbsp;



As more crops are tested for flavor, nutrition, and shelf life, humans gain the ability to grow food far from our planet. 



With input from experts like Gioia Massa, the future of in-space agriculture looks promising for both nourishment and crew satisfaction.

Space lettuce: NASA's plans to grow nutritious plants on Mars

NASA is examining ways to ensure explorers have nourishing produce,...

Out of all the planets in our solar system beyond Earth, most consider Saturn's beauty to be the most spectacular, with a set of rings that have inspired curiosity for hundreds of years. 



In the 17th century, Italian astronomer Galileo Galilei described this distant world as having "ears," showing how limited his view was at the time. 



Even with basic tools, he sensed something unusual about the planet’s appearance, although he could not fully explain it.



<h2 class="wp-block-heading" id="h-saturn-s-rings-steal-the-show">Saturn's rings steal the show</h2>



Modern telescopes and worldwide observatories have transformed our <a href="https://www.earth.com/news/massive-energy-imbalance-discovered-on-saturn/" target="_blank" rel="noreferrer noopener">understanding of Saturn</a>. They reveal swirling collections of ice and rocks orbiting the massive planet in broad arcs that we call rings. 



These ribbons of debris are more than a mere celestial decoration for us humans to admire; they shed light on the gravitational forces at work in our solar system.



By studying Saturn's rings, astronomers gain a better understanding of how cosmic particles behave when bound by gravity, and why their appearance changes when viewed from Earth. 



Jonah Peter, a doctoral student at Harvard-Smithsonian Center for Astrophysics (<a href="https://www.cfa.harvard.edu/" target="_blank" rel="noreferrer noopener">CfA</a>), has focused on how Saturn’s moons affect the <a href="https://www.earth.com/news/new-image-of-saturn-and-its-ring-spokes-from-the-hubble-space-telescope/" target="_blank" rel="noreferrer noopener">ring environment</a>.



His work connects the motions of this ring material to the broader story of our cosmic neighborhood, all of which is driven by a process known as orbital mechanics, or celestial mechanics. 



<h2 class="wp-block-heading" id="h-understanding-orbital-mechanics-the-basics">Understanding orbital mechanics - the basics</h2>



Orbital mechanics describes how bodies move under the pull of gravity. Planets circle the Sun, moons circle planets, and satellites stay in orbit around Earth. 



These paths depend on factors like velocity and orbital shape, all of which keep objects traveling in predictable loops.



Saturn’s tilt plays a role in how we see the rings. As the planet continues on its journey, our viewpoint changes over time. 



In some phases, the rings show off their full width. In others, they line up edge-on, turning into a thin band that seems ready to vanish.



<h2 class="wp-block-heading" id="h-how-saturn-s-rings-will-disappear">How Saturn's rings will disappear</h2>



A striking event called a "ring plane crossing" will occur on March 23, 2025. The rings will appear to have completely vanished because their thin edges will be aimed at Earth. 



This alignment happens when Saturn’s tilt and location match up so that we no longer see the bright swath of particles head-on. Once the rings vanish from easy sight in March 2025, Saturn will look like a pale yellow sphere through most telescopes. A subtle line may be visible around the planet’s middle, but only through the most powerful telescopes.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/01/saturn_rings_viewed-from-earth_orbital-mechanics_nasa_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/01/saturn_rings_viewed-from-earth_orbital-mechanics_nasa_1s.webp" alt="Rings A, B, C.

Some enthusiasts might miss the typical glow, yet there is a certain thrill in waiting for that grand display to reappear.



As Earth and Saturn shift positions, the rings will come back into full view around November 2025. The planet’s looping debris will stand out again, along with glimpses of its many moons. 



<a href="https://www.earth.com/news/megastorms-on-saturn-are-larger-than-the-earth-and-last-for-hundreds-of-years/" target="_blank" rel="noreferrer noopener">This recurring pattern</a> reminds observers that our perspective can change, even when Saturn itself remains the same majestic world it has always been.



<h2 class="wp-block-heading" id="h-composition-and-structure-of-saturn-s-rings">Composition and structure of Saturn's rings</h2>



The rings are <a href="https://www.earth.com/news/saturns-rings-may-have-formed-after-two-icy-moons-collided/" target="_blank" rel="noreferrer noopener">divided into sections</a> called the A, B, and C rings, plus a few fainter ones labeled D, E, F, and G. Between the A and B rings lies the Cassini Division, measuring around 2,982 miles wide. 



Scientists note that spaces like this can form when orbital motions and gravitational tugs clear out certain pathways.



These rings are not solid sheets. They're made of pieces that range from dust-size grains to lumps as large as buses. 



Some researchers think the rings sprang from a moon ripped apart by Saturn’s gravity. Others propose that leftover material from the planet’s formation helped craft <a href="https://www.earth.com/news/we-now-know-the-age-of-saturns-rings-and-the-number-might-surprise-you/" target="_blank" rel="noreferrer noopener">these looping bands</a> more than four billion years ago.



<h2 class="wp-block-heading" id="h-moons-and-their-gravitational-pull">Moons and their gravitational pull</h2>



Saturn hosts <a href="https://www.earth.com/news/saturn-now-leads-the-solar-system-moon-race-with-145/" target="_blank" rel="noreferrer noopener">at least 145 moons</a>. Some are called shepherd moons, and they drift near the ring edges. 



Their gravity holds ring particles in place, preventing them from scattering too far in one direction or another. This process helps the rings maintain their recognizable gaps and bands.



Beyond those shepherds, Saturn’s system includes larger bodies that have unique properties. <a href="https://www.earth.com/news/saturns-moon-titan-has-shorelines-shaped-by-waves/" target="_blank" rel="noreferrer noopener">The biggest, Titan</a>, is a place of ongoing study. It has an atmosphere mostly made of nitrogen. 



Scientists have also measured a magnetic field around Titan that, while weaker than Jupiter’s, surpasses Earth’s field in relative strength.

<a href="https://www.earth.com/news/dragonfly-space-mission-saturn-moon-titan-gets-greenlight/" target="_blank" rel="noreferrer noopener">NASA’s Dragonfly mission</a> plans to send an exploratory craft to Titan. Researchers are keen to learn more about its lakes of liquid hydrocarbons and the thick orange haze that hides much of its surface. 



These features hint at a landscape shaped by chemistry unlike anything on our planet.



Radio signals from Titan indicate bright auroras at the poles. These signals prove that electric and magnetic forces act in that moon’s environment. 



This unusual blend of ingredients prompts questions about how life might appear elsewhere, if it appears at all.

<a href="https://www.earth.com/news/life-on-saturns-moon-enceladus-massive-water-plume-has-scientists-wondering/" target="_blank" rel="noreferrer noopener">Enceladus</a>, another of Saturn’s moons, has drawn attention because of icy plumes venting from near its south pole. 



Observations from the Cassini mission revealed water vapor and possible chemical building blocks for living organisms. 



That discovery turned Enceladus into a point of interest for people searching for life in the solar system.



"Not only does Enceladus seem to meet the basic <a href="https://www.earth.com/news/life-sparking-energy-source-found-on-saturns-moon-enceladus/" target="_blank" rel="noreferrer noopener">requirements for habitability</a>, we now have an idea about how complex biomolecules could form there, and what sort of chemical pathways might be involved," explains Jonah Peter. These findings stir hope about discovering microbial life beyond Earth.



<h2 class="wp-block-heading" id="h-saturn-s-mystery-and-majesty">Saturn's mystery and majesty</h2>



Galileo’s old remark about Saturn’s "ears" underscores how far we have come. Early astronomers had limited tools, yet they still glimpsed something remarkable. 



Modern instruments add detail, but the sense of wonder remains. Saturn shows how our solar system is filled with surprises that motivate fresh discoveries.



As amateurs and experts keep pointing their lenses skyward, they continue to find reasons to appreciate this planet’s evolving appearance. 



The rings may fade from view temporarily, but people know they will return. Each phase allows us to learn a little more about how cosmic objects behave and how life might emerge under new conditions.

Saturn's rings will vanish in less than three months from now

Our buildings usually remain comfortable during warm days because of constant air conditioning, sealed windows, and an assumption that power never fails. But as large parts of the country have learned, blackouts can hit at the worst possible moment. 



When that happens, glass towers and sealed-off homes can quickly become stiflingly hot, showing why passive cooling methods are essential.



<h2 class="wp-block-heading" id="h-ancient-builders-had-better-cooling-methods">Ancient builders had better cooling methods</h2>



Ancient builders had no electricity, yet they made structures that protected people from the <a href="https://www.earth.com/news/2024-confirmed-as-earths-hottest-year-in-recorded-history/" target="_blank" rel="noreferrer noopener">worst heat</a>. Some devised thick walls that absorbed heat by day and released it at night.&nbsp;



Others planned entire neighborhoods to maximize shade. These time-tested ideas remain relevant for anyone who wants to stay cooler without cranking up the air conditioner.



This view is shared by Dr. Pablo La Roche, an architecture professor at <a href="https://www.cpp.edu/" target="_blank" rel="noreferrer noopener">California State Polytechnic University, Pomona</a>, and sustainable design director at <a href="https://www.arcadis.com/" target="_blank" rel="noreferrer noopener">Arcadis</a>.&nbsp;



With decades of research on passive cooling systems and low-energy architecture, his work highlights how historical construction techniques effectively addressed the <a href="https://www.earth.com/news/2024-shatters-heat-records-earths-hottest-year-is-here/" target="_blank" rel="noreferrer noopener">challenges of harsh climates</a> with intense summer heat.



<h2 class="wp-block-heading" id="h-how-ancient-iraq-managed-scorching-heat">How ancient Iraq managed scorching heat</h2>



Archaeologists have <a href="https://books.google.com/books?hl=en&amp;lr=&amp;id=xpTkEAAAQBAJ&amp;oi=fnd&amp;pg=PA3#v=onepage&amp;q&amp;f=false" target="_blank" rel="noreferrer noopener">documented</a> the Sumerians’ buildings in what is now southern Iraq. Walls made of mud brick or adobe were thick and had only small windows. This design helped reduce heat inside during the sun’s intense hours. 



In some places, homes were built side by side, so fewer walls were directly hit by sunlight. The neighborhoods also included narrow streets that created cooling shade as people walked through the city.



That compact arrangement worked when indoor temperatures had to stay tolerable. Families gathered in inner courtyards where light and breezes could get in but the scorching rays had trouble reaching the seating areas.



Some of these principles might still be practical in hot, urban environments today.



<h2 class="wp-block-heading" id="h-modern-cities-can-learn-from-passive-cooling">Modern cities can learn from passive cooling</h2>



Major power failures can be disastrous during a heat wave. In <a href="https://www.insurancejournal.com/news/southcentral/2024/07/22/784992.htm" target="_blank" rel="noreferrer noopener">July 2024</a>, the Houston area lost electricity for several days. When air conditioning shut off, many high-rises became uncomfortable in a hurry.&nbsp;



Some designers suggest that reintroducing features like operable windows, thicker walls, or rooftop shade structures might help with indoor temperature control and lower energy consumption at the same time.



Studies indicate that extremely hot summers are occurring more <a href="https://jamanetwork.com/journals/jama/article-abstract/2822854" target="_blank" rel="noreferrer noopener">frequently</a>. Placing more emphasis on passive cooling could reduce the stress on power grids and keep people safer when the grid goes down.



<h2 class="wp-block-heading" id="h-egypt-s-simple-but-clever-wind-catchers">Egypt’s simple but clever wind catchers</h2>



In ancient Egypt, builders knew that porous materials such as mud brick would block intense sunlight and slow the movement of <a href="https://www.earth.com/news/mapping-2024s-record-heat-unveiling-earths-climate-danger-zones/" target="_blank" rel="noreferrer noopener">heat</a> indoors. Residents also slept outdoors on rooftops at night, taking advantage of the cooler air.&nbsp;



One striking invention was the <a href="https://www.egyptianarch.com/post/mulqaf-origin-language-design-and-development" target="_blank" rel="noreferrer noopener">mulqaf</a>, which used a tall opening to catch breezes and push them downward into a building. 



That airflow let hot indoor air escape through other vents. This system is still used in parts of the Middle East, where tall <a href="https://www.archdaily.com/971216/what-is-a-traditional-windcatcher" target="_blank" rel="noreferrer noopener">wind catchers</a> provide fresh air without the need for electricity.



<h2 class="wp-block-heading" id="h-secrets-from-the-ancient-puebloans">Secrets from the ancient Puebloans</h2>



In the U.S. Southwest, the ancestral <a href="https://blog.nativehope.org/pueblo-native-americans-their-history-culture-and-traditions" target="_blank" rel="noreferrer noopener">Puebloans</a> built with mud brick and stone for many centuries. They placed dwellings close together and used smaller windows to limit excessive heat. Cliffs provided natural shade in places like <a href="https://greenpassivesolar.com/2010/04/mesa-verde-cliff-dwellings/" target="_blank" rel="noreferrer noopener">Mesa Verde</a>.&nbsp;



The layout took advantage of the sun’s angle to block the harsh summer rays and let in lower winter sunlight that warmed the interior.



These older methods still guide some modern builders who adopt adobe for its ability to moderate indoor temperatures.



<h2 class="wp-block-heading" id="h-preserving-water-for-passive-cooling">Preserving water for passive cooling</h2>



Many cities today send rainwater away as quickly as possible through storm drains. Old societies in arid regions did the opposite. 



During the eighth century, the Muslim caliphates in northern Africa and southern Spain put a high value on every drop of rain. Their structures often had <a href="https://www.doi.org/10.1007/978-3-031-38028-0" target="_blank" rel="noreferrer noopener">systems</a> that channeled water from rooftops and courtyards into underground cisterns. That water cooled patios and irrigated gardens during scorching months.



In other parts of the world, societies like the Mayans in Mexico built huge <a href="https://link.springer.com/book/9783031577307" target="_blank" rel="noreferrer noopener">reservoirs</a> to store the wet-season rainfall. Modern <a href="https://www.sciencedirect.com/science/article/abs/pii/S0301479721002851?via%3Dihub" target="_blank" rel="noreferrer noopener">researchers</a> are exploring ways to adopt or improve rainwater harvesting, especially in places threatened by droughts or limited water supplies.



<h2 class="wp-block-heading" id="h-adapting-passive-cooling-ideas-today">Adapting passive cooling ideas today</h2>



Some architects believe that new designs should rely more on passive cooling and water collection. Orienting buildings in the northern hemisphere to take advantage of south-facing windows can help regulate <a href="https://www.earth.com/news/scorching-summer-of-2024-could-make-it-the-hottest-year-on-record/" target="_blank" rel="noreferrer noopener">heat</a> gain and loss (International Association of Certified Home Inspectors). 



Rainwater captured onsite can be <a href="https://www.energy.gov/femp/rainwater-harvesting-systems-technology-review" target="_blank" rel="noreferrer noopener">reused</a> for landscape needs, thus reducing the burden on public water supplies.



Larger cities that hope to reduce their energy usage and keep people safe during emergencies could integrate these techniques into upcoming developments. Some methods might look old-fashioned compared to modern high-rises.&nbsp;



Yet people who live in the world’s driest and hottest places have been testing these approaches for a long time, and their successes can offer strong guidance.



<h2 class="wp-block-heading" id="h-moving-forward-with-less-power-dependence">Moving forward with less power dependence</h2>



There is a growing call to learn from strategies that rely on local resources. Converting entire cities will take effort, but these ideas do not belong in the distant past.&nbsp;



There is a need to reconsider glassy towers and single-purpose rooftops, especially as blackouts become an increasing risk in regions experiencing more frequent <a href="https://www.earth.com/news/climate-change-added-41-extra-days-of-dangerous-heat-in-2024/" target="_blank" rel="noreferrer noopener">heat waves</a>. 



Historical knowledge of staying cool in extreme heat could provide valuable solutions for maintaining comfort when air conditioning is not an option.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.
