Today's Image of the Day from the European Space Agency features NGC 6744 - a large, barred spiral galaxy located approximately 30 million light-years away in the constellation Pavo.&nbsp;



The galaxy is often considered a close analog to the <a href="https://www.earth.com/news/uma3-u1-faintest-star-system-found-orbiting-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">Milky Way</a> due to its similar structure and size, spanning about 175,000 light-years across.&nbsp;



<h2 class="wp-block-heading" id="h-euclid-space-mission-nbsp">Euclid space mission&nbsp;</h2>



The image was captured by the <a href="https://www.esa.int/Science_Exploration/Space_Science/Euclid" target="_blank" rel="noreferrer noopener">Euclid</a> space telescope. NGC 6744 stands out as a prime example of the galaxies currently forming the majority of stars in the nearby universe, making it an ideal subject for study with the Euclid mission.&nbsp;



Euclid’s extensive field-of-view allows it to capture the entire galaxy, showcasing not only its large-scale spiral structure but also revealing intricate details on smaller scales across various wavelengths. These details include feather-like dust lanes, known as “spurs,” emerging from the spiral arms.



<h2 class="wp-block-heading" id="h-star-formation-in-ngc-6744">Star formation in NGC 6744</h2>



Euclid's observations enable scientists to count individual stars within NGC 6744, trace the distribution of stars and dust throughout the galaxy, and map the dust associated with the gas that fuels the development of new stars. 



<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> is a key process in the growth of galaxies, making these studies crucial for understanding galaxy evolution.



Researchers are utilizing Euclid’s data to explore the relationship between dust, gas, and star formation; to map the distribution of different stellar populations and identify regions of active star formation; and to investigate the underlying physics of spiral galaxy structures.&nbsp;



Spiral arms play a significant role in star formation by compressing gas, yet the precise mechanisms behind this process are still unclear. The presence of “spurs” along NGC 6744’s spiral arms offers valuable insights into the dynamics of star formation within these structures.



<h2 class="wp-block-heading" id="h-discovering-new-dwarf-galaxies-nbsp">Discovering new dwarf galaxies&nbsp;</h2>



Additionally, Euclid's dataset will help scientists identify clusters of old stars (globular clusters) and discover new dwarf galaxies around NGC 6744. Remarkably, Euclid has already identified a new dwarf satellite galaxy of NGC 6744 - a surprising discovery given that the galaxy has been studied extensively.



With Euclid’s detailed observations, scientists are gaining a deeper understanding of the processes shaping galaxies, providing essential clues to the evolution and appearance of the <a href="https://www.earth.com/news/universes-expansion-rate-hubble-tension-puzzles-astronomers/" target="_blank" rel="noreferrer noopener">universe</a>.



<h2 class="wp-block-heading" id="h-more-about-ngc-6744">More about NGC 6744</h2>



NGC 6744's disk is rich in star-forming regions and contains numerous young, bright blue stars. The galaxy's nucleus is slightly elongated and has a bar structure, which influences the motion of the stars and gas within it.&nbsp;



The spiral arms of NGC 6744 are well-defined and extend outward, wrapping around the central bar. Additionally, NGC 6744 has a smaller companion galaxy, NGC 6744A, which is interacting with it, adding to the complexity and interest of this distant system.&nbsp;



<h2 class="wp-block-heading" id="h-spiral-galaxies">Spiral galaxies</h2>



<a href="https://www.earth.com/news/the-mesmerizing-beauty-of-spiral-galaxies/" target="_blank" rel="noreferrer noopener">Spiral galaxies</a> are one of the most common types of galaxies in the universe, characterized by their distinct, spiral-shaped structure.&nbsp;



The galaxies typically consist of a flat, rotating disk containing stars, gas, and dust, along with a central concentration of stars known as the bulge. This bulge is often surrounded by a halo of older stars.&nbsp;



The spiral arms, which extend from the central bulge, are regions of active star formation and are rich in young, hot stars, giving them a bright, bluish appearance.&nbsp;



These arms are also sites where interstellar gas and dust are concentrated, leading to the formation of new stars.&nbsp;



Spiral galaxies are classified into different types based on the tightness of their spirals and the size of their central bulge, with classifications ranging from tightly wound arms in Sa galaxies to more loosely wound arms in Sc galaxies. The <a href="https://www.earth.com/news/large-amount-of-dark-matter-may-be-missing-from-the-milky-way/" target="_blank" rel="noreferrer noopener">Milky Way</a>, our home galaxy, is a prime example of a spiral galaxy.



<h2 class="wp-block-heading" id="h-the-constellation-pavo">The constellation Pavo</h2>



Pavo, which means "peacock" in Latin, is a constellation in the southern sky. It was named by the Dutch astronomer Petrus Plancius in the late 16th century, based on observations made during the Dutch explorations of the southern hemisphere. 



Pavo is one of the 12 constellations created by Plancius from the records of explorers Pieter Dirkszoon Keyser and Frederick de Houtman. 



The constellation is known for its distinctive shape, resembling a peacock with a long, curved tail. Pavo is not visible from most of the northern hemisphere, but it can be seen from the southern hemisphere, particularly during the winter months.



The constellation contains several interesting celestial objects, including the star Peacock, also known as Alpha Pavonis, which is the brightest star in the constellation. This star is a blue-white subgiant located about 179 light-years from Earth.

Spiral galaxy NGC 6744 in the constellation Pavo

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

Today's Image of the Day from NASA Earth Observatory features an active landslide zone that has been shifting for decades on the Palos Verdes Peninsula in Los Angeles County.



This area, particularly in Portuguese Bend, experiences ongoing ground movement, with land sliding toward the ocean at varying rates - sometimes moving several feet per year.&nbsp;



The instability is largely due to weak, water-saturated bedrock and the effects of <a href="https://www.earth.com/news/rising-seas-sinking-cities-land-subsidence-on-the-east-coast/">human activity</a>, including road construction and irrigation, which have exacerbated the natural movement.



<h2 class="wp-block-heading" id="h-analysis-of-the-landslide-zone">Analysis of the landslide zone</h2>



According to a recent report from NASA, the landslide zone on the Palos Verdes Peninsula has expanded.&nbsp;



“Researchers at NASA’s Jet Propulsion Laboratory in Southern California used data from an airborne radar to measure the movement of the slow-moving landslides on the Palos Verdes Peninsula in Los Angeles County,” the <a href="https://earthobservatory.nasa.gov/images/153893/los-angeles-area-landslide-expands">report</a> stated.



“The analysis determined that, during a four-week period in the fall of 2024, land in the residential area slid toward the ocean by as much as 4 inches (10 centimeters) per week."



“Portions of the peninsula, which juts into the Pacific Ocean just south of the city of Los Angeles, are part of an ancient complex of landslides that has been moving for at least the past six decades, affecting hundreds of buildings in local communities.”&nbsp;



NASA noted that the motion accelerated and the active area expanded following record-breaking rainfall in Southern California in 2023 and heavy <a href="https://www.earth.com/news/rainfall-is-increasingly-unpredictable-due-to-climate-change/" target="_blank" rel="noreferrer noopener">precipitation</a> in early 2024.



<h2 class="wp-block-heading" id="h-visualization-of-the-landslide-zone">Visualization of the landslide zone</h2>



To create the image, the Advanced Rapid Imaging and Analysis (ARIA) team used data from four flights of NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) collected between September 18 and October 17, 2024.&nbsp;



“The UAVSAR instrument was mounted to a Gulfstream III jet flown out of NASA’s Armstrong Flight Research Center in Edwards, California, and the four flights were planned to estimate the speed and direction of the landslides in three dimensions,” explained NASA.



“In the image above, colors indicate how fast parts of the landslide complex were moving in late September and October, with the darkest reds indicating the highest speeds." 



"The arrows represent the direction of horizontal motion. The white solid lines are the boundaries of the active landslide area as defined in 2007 by the California Geological Survey.”



<h2 class="wp-block-heading" id="h-accelerating-land-movement-and-risks">Accelerating land movement and risks</h2>



Alexander Handwerger is a landslide scientist at the Jet Propulsion Laboratory who performed the analysis. “In effect, we’re seeing that the footprint of land experiencing significant impacts has expanded, and the speed is more than enough to put human life and infrastructure at risk,” said Handwerger. 



The landslide activity in this region dates back to the 1950s, when road construction projects disturbed the already <a href="https://www.earth.com/news/two-billion-people-are-threatened-by-land-subsidence/">unstable terrain</a>, accelerating movement.&nbsp;



Since then, shifting ground has led to significant damage to infrastructure, including cracked roads, broken utility lines, and distorted buildings. The instability has made it difficult for the city to maintain roads and essential services in the affected areas.



Despite efforts to slow the movement, including drainage improvements and engineering solutions, the land continues to shift. Homeowners and city officials have had to adapt, with some structures built to withstand slow movement, while others have been abandoned.&nbsp;



The situation remains a challenge, with scientists monitoring the landslide to better understand its <a href="https://www.earth.com/news/landslide-predictions-could-become-94-percent-more-accurate/">behavior</a> and explore potential mitigation strategies.



Portuguese Bend is a well-known example of a continuously active landslide, highlighting the complex interaction between geology, human development, and environmental forces.

Landslide zone in Los Angeles County is expanding

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

Today's Image of the Day from the European Space Agency features a Copernicus Sentinel-2 photograph of South Georgia, a remote and rugged island located in the southern Atlantic Ocean. 



"Linked with the South Sandwich Islands to form a British Overseas Territory, this southern Atlantic island is a haven for a vast array of wildlife," said <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.



"Around five million seals call the islands home, as well as 65 million birds of 30 different species. Migrating whales and various fish species populate the surrounding waters and there is a large penguin population."



<h2 class="wp-block-heading" id="h-climate-and-wildlife-of-south-georgia">Climate and wildlife of South Georgia </h2>



The island is dominated by mountains, glaciers, and fjords. Its highest peak, Mount Paget, rises to 2,935 meters, making it one of the tallest in the region.



South Georgia’s location within the Antarctic Convergence gives it a cold, maritime climate. Although not part of the Antarctic Treaty System, its environment and <a href="https://www.earth.com/news/conservation-efforts-are-not-enough-to-save-antarctic-wildlife/" target="_blank" rel="noreferrer noopener">wildlife</a> are closely linked to Antarctica. 



The island is home to vast colonies of penguins, seals, and seabirds. The surrounding waters are rich with krill, providing an abundant food source for marine life.



<h2 class="wp-block-heading" id="h-penguins-adapted-to-harsh-environments">Penguins adapted to harsh environments </h2>



The most notable species found here are the king penguins, which are the second-largest penguin species in the world. South Georgia also hosts large populations of <a href="https://www.earth.com/news/what-makes-the-gentoo-penguin-the-worlds-fastest-swimming-bird/" target="_blank" rel="noreferrer noopener">gentoo</a> and macaroni penguins. 



The island's harsh climate, characterized by strong winds, snow, and cold temperatures, makes it a tough environment, but the penguins have adapted well. 



Their colonies - some of which number in the hundreds of thousands - can be found along the island's rugged coasts and beaches. 



The island’s isolation, combined with its plentiful food supply, makes it a critical breeding ground for these penguins.



<h2 class="wp-block-heading" id="h-history-of-south-georgia">History of South Georgia </h2>



The island has a history of exploration and exploitation. Captain James Cook first claimed South Georgia for Britain in 1775. 



During the late 19th and early 20th centuries, it became a hub for the <a href="https://www.earth.com/news/echoes-of-the-past-whalings-long-term-impact-on-genetic-diversity/" target="_blank" rel="noreferrer noopener">whaling</a> industry, with stations like Grytviken serving as operational centers. These stations have since been abandoned, and the island is now a haven for scientific research and ecotourism.



South Georgia is also notable for its role in Ernest Shackleton’s famed Endurance expedition. His crew reached the island in 1916 after an extraordinary open-boat journey from Elephant Island. Shackleton later died on South Georgia in 1922 and is buried in Grytviken.



<h2 class="wp-block-heading" id="h-pristine-nature-of-the-island">Pristine nature of the island</h2>



Today, South Georgia is a focus of conservation efforts. The eradication of invasive species, such as rats and reindeer, has been a significant success, allowing native wildlife to recover. 



Rats and mice were responsible for the decline of ground-nesting birds, including the South Georgia pipit, the island's only endemic bird. 



<a href="https://www.earth.com/news/reindeer-use-ultraviolet-vision-to-find-food-in-the-winter/" target="_blank" rel="noreferrer noopener">Reindeer</a>, which had been introduced for farming in the 19th century, caused extensive damage to the island’s vegetation, disrupting the habitat for native species.



South Georgia is uninhabited except for a small number of scientists and staff working at research stations and administrative facilities, emphasizing its role as a protected wilderness area and an essential site for understanding global environmental changes.



Its uninhabited status has helped preserve its pristine nature. Visitors to South Georgia must follow strict environmental guidelines to minimize human impact on this extraordinary island.



<h2 class="wp-block-heading" id="h-scientific-significance-of-remote-islands">Scientific significance of remote islands </h2>



Remote <a href="https://www.earth.com/news/plant-life-on-islands-loses-diversity-when-humans-arrive/" target="_blank" rel="noreferrer noopener">islands</a> are scientifically significant for several reasons. They often serve as unique ecosystems that can provide insights into evolutionary processes, biodiversity, and adaptation. 



Due to their isolation, species on remote islands may evolve differently from their mainland counterparts, resulting in the development of endemic species that exist nowhere else in the world. 



These islands also act as natural laboratories for studying the effects of climate change, human activity, and ecological interactions, as they are more vulnerable to disturbances. 



Moreover, remote islands can offer valuable information on the health of marine and terrestrial ecosystems, as their ecosystems are often less impacted by human-induced factors. This makes them ideal for studying natural processes in relatively undisturbed environments. 



The isolation of these islands can also help scientists study the patterns of species migration, colonization, and extinction.

South Georgia: One of the most remote islands in the world

Today's Image of the Day from the European Space Agency features a brilliant stellar nursery located about 163,000 light-years away.



According to ESA, the image is one of the most photogenic examples of the many stellar nurseries observed by the NASA/ESA Hubble Space Telescope during its 30-year lifetime. 



“The portrait features the giant nebula NGC 2014 and its neighbor NGC 2020 which together form part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way,” noted <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.



<h2 class="wp-block-heading" id="h-what-is-a-stellar-nursery">What is a stellar nursery?</h2>



Stellar nurseries are regions in space where new stars are <a href="https://www.earth.com/news/baby-stars-release-sneezes-of-gas-and-dust-as-they-develop/" target="_blank" rel="noreferrer noopener">born</a> - often within vast clouds of gas and dust called molecular clouds.&nbsp;



These areas are fascinating because they are cradles of stellar evolution, where gravity causes clumps of gas to collapse, eventually forming protostars.&nbsp;



Over time, the protostars will heat up and start the nuclear fusion process that powers a star.



One of the most well-known stellar nurseries is the Orion Nebula, which is visible to the naked eye and located about 1,350 light-years from Earth.&nbsp;



<h2 class="wp-block-heading" id="h-dynamic-nature-of-a-stellar-nursery-nbsp">Dynamic nature of a stellar nursery&nbsp;</h2>



Within these nurseries, the balance between gravity and pressure determines the types of stars that form, from massive, luminous stars to smaller, cooler ones like our Sun.&nbsp;



The environment is incredibly dynamic, with powerful winds from young stars shaping the clouds and triggering the birth of even more stars.



These regions are often illuminated by the light from massive newborn stars - creating stunning, colorful displays. The light reveals the intricate structure of the dust and gas, sculpted by the energy of young stars.&nbsp;



<h2 class="wp-block-heading" id="h-significance-of-stellar-nurseries-nbsp">Significance of stellar nurseries&nbsp;</h2>



Stellar nurseries are essential for understanding the early stages of planetary formation, as protoplanetary disks (the material from which <a href="https://www.earth.com/news/planet-formation-new-insights-mechanics-physics/" target="_blank" rel="noreferrer noopener">planets form</a>) are often found around young stars in these regions.



Stellar nurseries play a crucial role in the ongoing evolution of <a href="https://www.earth.com/news/black-hole-is-starving-its-host-galaxy-of-star-forming-fuel/" target="_blank" rel="noreferrer noopener">galaxies</a>. They are responsible for the continuous birth of new stars that enrich the interstellar medium with heavier elements. This constant recycling of material is key to the development of future generations of stars and planets.&nbsp;



Furthermore, the study of these regions helps astronomers understand the fundamental processes that govern the life cycles of stars and the overall dynamics of the universe.



<h2 class="wp-block-heading" id="h-the-local-group">The Local Group</h2>



The Local Group is a collection of over 80 galaxies that includes the Milky Way, the Andromeda Galaxy, and the Triangulum Galaxy, along with numerous smaller dwarf galaxies. These galaxies are bound together by gravity and span a region roughly 10 million light-years across.&nbsp;



The <a href="https://www.earth.com/news/milky-ways-thin-disk-is-billions-of-years-older-than-we-thought/" target="_blank" rel="noreferrer noopener">Milky Way</a> and Andromeda are the dominant members, with their respective satellite galaxies orbiting them.&nbsp;



The Local Group is part of a larger structure known as the Virgo Supercluster, and its galaxies are moving toward the gravitational center of the Local Group, contributing to its dynamic nature.&nbsp;



<h2 class="wp-block-heading" id="h-large-magellanic-cloud">Large Magellanic Cloud</h2>



The Large Magellanic Cloud (LMC) is the fourth largest galaxy in the Local Group and can be seen with the naked eye from the Southern Hemisphere.&nbsp;



This irregular dwarf galaxy is home to the Tarantula Nebula, one of the most active star-forming regions in our cosmic neighborhood.&nbsp;



The Large Magellanic Cloud played a key role in astronomical history, particularly when the supernova SN 1987A was observed, providing valuable insights into stellar evolution.&nbsp;



The LMC's interaction with the Milky Way, along with its own companion, the Small Magellanic Cloud, is believed to influence its shape and star formation activity. Its proximity and unique properties make it a crucial object of study for understanding <a href="https://www.earth.com/news/massive-galactic-explosion-provides-clues-about-galaxy-evolution/" target="_blank" rel="noreferrer noopener">galaxy evolution</a>, star formation, and the dynamics of interacting galaxies.

Hubble captures a stunning stellar nursery

Today's Image of the Day from the European Space Agency features the star-forming region NGC 604. The nebula is located 2.73 million light-years away from Earth in the Triangulum Galaxy (M33). 



By studying regions like NGC 604, astronomers can gain insights into the complex interactions between stars and the interstellar medium, as well as the conditions that lead to the birth of stars. This, in turn, helps in understanding the evolution of <a href="https://www.earth.com/news/galaxies-like-our-own-milky-way-are-not-unique/" target="_blank" rel="noreferrer noopener">galaxies</a> and the universe as a whole.



<h2 class="wp-block-heading" id="h-massive-stars-of-ngc-604">Massive stars of NGC 604</h2>



"Sheltered among NGC 604’s dusty envelopes of gas are more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives," said <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.



"These types of stars are known as B-types and O-types, the latter of which can be more than 100 times the mass of our own Sun. It’s quite rare to find this concentration of them in the nearby universe. In fact, there’s no similar region within our own Milky Way galaxy."



According to ESA, this concentration of massive stars, combined with its relatively close distance, means that NGC 604 gives astronomers an opportunity to study these objects at a fascinating time early in their life.



<h2 class="wp-block-heading" id="h-gigantic-region-of-ionized-hydrogen">Gigantic region of ionized hydrogen</h2>



NGC 604 is one of the largest known regions of ionized hydrogen, also known as an H II region. This nebula is significantly larger than the Orion Nebula, which is one of the most well-known H II regions in our own <a href="https://www.earth.com/news/large-amount-of-dark-matter-may-be-missing-from-the-milky-way/" target="_blank" rel="noreferrer noopener">Milky Way galaxy</a>.&nbsp;



NGC 604 spans about 1,500 light-years across, making it one of the largest H II regions in the Local Group of galaxies. This group includes the Milky Way, the Andromeda Galaxy, and about 54 other smaller galaxies.&nbsp;



<h2 class="wp-block-heading" id="h-ngc-604-starburst-phenomenon">NGC 604 starburst phenomenon </h2>



Within NGC 604, there are hundreds of young, hot, massive <a href="https://www.earth.com/news/stars-at-the-edge-of-our-milky-way-galaxy-travel-more-slowly/" target="_blank" rel="noreferrer noopener">stars</a>. These stars have ionized the surrounding gas, causing it to glow and creating the nebula. The region is a prime example of a starburst phenomenon, where stars form at a much higher rate than in typical galactic conditions.



“The bright orange streaks in this image signify the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons, or PAHs," explained ESA.



"As you travel further from the immediate cavities of dust where the star is forming, the deeper red signifies molecular hydrogen. This cooler gas is a prime environment for star formation. Ionized hydrogen from ultraviolet radiation appears as a white and blue ghostly glow."



<h2 class="wp-block-heading" id="h-more-about-star-formation">More about star formation </h2>



Star formation is crucial for the evolution of galaxies and the synthesis of heavy elements. In the cores of stars, elements heavier than helium are created.



The elements are spread throughout the <a href="https://www.earth.com/news/ancient-stars-shakti-shiva-shaped-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">galaxy</a> when stars reach the end of their lives and expel their material - either gently through winds or violently via supernova explosions. 



This enriching process allows for the formation of new stars and planets, and ultimately, the potential for life.



<h3 class="wp-block-heading">Cloud collapse</h3>



The process begins when part of a molecular cloud becomes unstable and starts to collapse under its own gravity. This can be triggered by events like shock waves from nearby <a href="https://www.earth.com/news/supernova-explosions-could-damage-distant-planets/" target="_blank" rel="noreferrer noopener">supernovae</a>, galactic collisions, or the influence of other massive stars.



<h3 class="wp-block-heading">Formation of a protostar</h3>



As the cloud collapses, it fragments into smaller clumps. Each clump will eventually form one or more stars. 



The material within these clumps continues to fall inward, heating up as it does so, eventually forming a warm core called a protostar. At this stage, the protostar is not yet hot enough for nuclear fusion (the process that powers stars) to occur.



<h3 class="wp-block-heading">Accretion disk</h3>



Around the protostar, material from the surrounding cloud continues to fall inward, forming a rotating disk. This material slowly accretes onto the protostar, increasing its mass.



<h3 class="wp-block-heading">Nuclear fusion begins</h3>



Once the core of the protostar reaches a high enough temperature and pressure, hydrogen atoms begin to fuse into helium, releasing energy in the process. This marks the transition from a protostar to a main sequence star, like our sun.



<h3 class="wp-block-heading">Main sequence and beyond</h3>



The star will spend the majority of its life in the main sequence stage, where it balances the gravitational forces trying to collapse it and the outward pressure from nuclear fusion. 



Eventually, the star will exhaust its hydrogen fuel. Its subsequent evolution will depend on its initial mass, leading to various end stages such as red giants, supernovae, neutron stars, or black holes.

Young, massive stars in the Triangulum Galaxy

New research suggests that a playful mindset can be instrumental during difficult times, such as the COVID-19 pandemic. Individuals who score high on a playfulness scale exhibit stronger resilience compared to less playful counterparts. 



The findings indicate that this resource is essential to maintaining well-being and facing adversity.



<h2 class="wp-block-heading" id="h-the-power-of-playfulness">The power of playfulness</h2>



The research, conducted by researchers at <a href="https://oregonstate.edu/" target="_blank" rel="noreferrer noopener">Oregon State University</a> (OSU), offers profound insights into how playful people navigate adversity.



The research may ultimately guide the development of strategies and interventions aimed at helping individuals handle <a href="https://www.earth.com/news/stress-eats-away-our-brains-cognitive-defenses/" target="_blank" rel="noreferrer noopener">stress</a> and uncertainty.



These findings are timely, given the increasing global challenges that demand both a realistic assessment and creative adaptation.



Xiangyou “Sharon” Shen of the OSU Health, Environment, and Leisure Research Lab (HEAL) is the study's lead author.



"Understanding how playful people navigate adversity can inform interventions and strategies to help people cope with stress and uncertainty," said Shen. 



"They shared similar perceptions of risk and protective factors as their less playful peers, but demonstrated greater optimism when envisioning future possibilities, engaged in more creative problem solving, and managed to infuse quality and enjoyment into everyday activities."



<h2 class="wp-block-heading" id="h-pandemic-stress-and-public-health">Pandemic stress and public health</h2>



Chronic stress is a significant public health concern in the United States, linked to a wide range of health problems including heart disease, diabetes, depression, and <a href="https://www.earth.com/news/teachers-experienced-high-anxiety-during-the-pandemic/" target="_blank" rel="noreferrer noopener">anxiety</a>. 



External factors like the pandemic, economic uncertainty, and social issues can exacerbate stress levels and contribute to mental health diagnoses.



For the analysis, Shen and study co-author Zoe Crawley divided a group of more than 500 U.S. adults into two subgroups based on their levels of playfulness, as measured by the Adult Playfulness Trait Scale.



Shen noted that highly playful individuals actively altered challenging situations, found creative substitutes for what was lost, viewed obstacles as opportunities for growth, and maintained a strong sense of control over their responses.



Perhaps most revealing, she added, was that while the highly playful didn’t necessarily engage in different activities or do them more often than their less playful counterparts, they experienced those activities with higher quality - demonstrating greater immersion, activeness, and positive affect.



<h2 class="wp-block-heading" id="h-playful-people-during-the-pandemic">Playful people during the pandemic </h2>



Shen describes the approach of creating <a href="https://www.earth.com/news/dopamine-helps-us-learn-from-positive-and-negative-experiences/" target="_blank" rel="noreferrer noopener">positive experiences</a> amid adversity as "making lemonade from lemons." 



This is deeply connected with resilience as it combines realistic assessment with flexible problem-solving, which offers a clear demonstration of how personality traits like playfulness shape our responses to stress.



"Highly playful people were just as realistic about COVID-19 risks and challenges as others, but they excelled at ‘lemonading’ - creatively imagining and pursuing the positive, discovering ways to create moments of joy even in difficult circumstances," said Shen.



<h2 class="wp-block-heading" id="h-playful-advantage-in-a-pandemic">Playful advantage in a pandemic</h2>



While it has been widely accepted that playful people "reframe" situations to make them more enjoyable, these findings suggest that it is not about wearing "rose-colored glasses." 



Playful individuals maintain their ability to view <a href="https://www.earth.com/news/consciousness-may-stem-from-unseen-dimensions-beyond-our-reality/" target="_blank" rel="noreferrer noopener">reality</a> as it is while finding the silver linings.



Shen emphasized that playfulness doesn't distort reality - it enhances it, offering specific ways in which this trait helps individuals navigate challenging times.



<h2 class="wp-block-heading" id="h-playfulness-can-be-cultivated">Playfulness can be cultivated</h2>



The study also suggests several approaches to cultivate playfulness, including engaging in activities that provoke joy and curiosity, embracing new experiences, creating opportunities for spontaneous exploration, spending time with inspiring, fun-loving people, and appreciating moments of silliness and humor.



"A key to all of this is focusing on the quality of engagement rather than simply doing what might be called play activities. True playfulness doesn’t require a playground, games, or toys. It’s about bringing a spirit of openness, flexibility, and fun to everyday moments," noted Shen.



She also emphasized that setting aside time for play can be beneficial, providing a safe space to express and practice playfulness. 



<h2 class="wp-block-heading" id="h-navigating-life-s-biggest-challenges">Navigating life's biggest challenges </h2>



No matter how occupied you might be, dedicating five to ten minutes daily for a small dose of play can make a meaningful difference in your life.



This research represents a significant step toward understanding the role of playfulness in helping individuals navigate challenging situations. 



In the context of our current global challenges - whether economic uncertainty, environmental concerns, or public health crises - the insights are invaluable.

Playful people handled pandemic stress better than others

New research suggests that a playful mindset can be instrumental...

Observers watching baboons in Namibia were impressed when they saw how the baboons responded to glowing spots shone onto their arms and legs. They poked and scratched at these bright areas with evident curiosity, hinting at a level of awareness about what appeared on their own bodies. 



However, the mood changed when those same spots were placed on baboon body parts that were only visible in a mirror.



Although they sometimes stared at their own reflection, the baboons showed no indication that they knew the marks in the mirror were on themselves.



Dr. Alecia Carter, affiliated with University College London (UCL Anthropology), led a field study tracking these baboons over several months. Her team documented how baboons interacted with laser marks and mirrors while in a wide-open habitat.



<h2 class="wp-block-heading" id="h-self-recognition-in-animals">Self-recognition in animals</h2>



The mirror test has long been used to examine whether <a href="https://www.earth.com/news/what-animal-will-replace-humans-as-earths-dominant-species-this-scientist-has-an-idea/" target="_blank" rel="noreferrer noopener">animals</a> recognize a reflected image as their own. 



Psychologist Gordon Gallup was among the first to observe that some great apes touched paint marks on their heads when placed in front of mirrors.



Subsequent efforts revealed that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC33317" target="_blank" rel="noreferrer noopener">dolphins</a> and a few <a href="https://www.pnas.org/doi/10.1073/pnas.0608062103" target="_blank" rel="noreferrer noopener">elephants</a> also showed behavior suggesting they noticed marks on their bodies through reflection. These findings inspired further research into how different animals handle the challenge of seeing themselves.



<h2 class="wp-block-heading" id="h-why-baboons-were-chosen">Why baboons were chosen </h2>



Scientists wanted to see if wild baboons that had never been in captivity, would respond differently than <a href="https://www.earth.com/news/ai-monitoring-will-help-protect-endangered-spider-monkeys/" target="_blank" rel="noreferrer noopener">animals</a> in controlled environments.



Many earlier studies used limited samples, often involving apes or monkeys that were kept in enclosures where mirrors might not be entirely new.



Chacma baboons flourish in Namibia’s drier areas and do not often encounter reflective surfaces. This made them good candidates for determining whether they would link the moving shapes in a mirror to their own bodies.



<h2 class="wp-block-heading" id="h-baboons-with-mirrors-and-laser-spots">Baboons with mirrors and laser spots</h2>



Researchers introduced small safety mirrors near spots where baboons congregate. They then used laser pointers to place harmless green or red marks on the baboons’ fur, targeting areas that were visible without a mirror and other places that were only visible when looking at a reflection.



Baboons frequently touched or scratched at marks they could see right away. Yet the animals showed no equivalent reaction to marks that were only apparent in a mirror.



<h2 class="wp-block-heading" id="h-results-of-the-baboon-mirror-test">Results of the baboon mirror test</h2>



“The Chacma baboons we observed in Tsaobis Nature Park certainly enjoyed using the mirrors as a new toy, but throughout our study they didn’t quite understand that the mirror’s reflection represented their own bodies,” said Dr. Carter.



She and her collaborators believe it confirms a pattern seen in many monkey species that do not show full self-recognition in mirrors.



“Monkeys don’t spontaneously recognize themselves in a mirror,” noted corresponding author Esa A. Ahmad, who helped analyze the data. 



The experts explained that this latest work adds to a broader discussion about which mental abilities are needed to pass mirror tests.



<h2 class="wp-block-heading" id="h-what-about-other-species">What about other species?</h2>



Some great apes, including <a href="https://www.earth.com/news/great-apes-will-suffer-through-frequent-and-extreme-climate-events/" target="_blank" rel="noreferrer noopener">chimpanzees</a>, bonobos, and orangutans, have been documented to pass mirror mark tests. 



Researchers also mention bottlenose dolphins, Asian elephants, and certain birds, like <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2517622/">magpies</a>, that appear to notice a mark when seeing it in a reflection.



Domestic cats, dogs, and most monkeys typically fail to show convincing self-recognition. Scientists point out that these animals may rely more on other senses, so a mirror might not be the best measure of how they perceive themselves.



<h2 class="wp-block-heading" id="h-possible-future-directions">Possible future directions</h2>



Some experts suggest that alternative experiments might capture different kinds of self-awareness in species that depend less on vision. 



Scent-based or social-behavior tasks could reveal that some animals are aware of their identity but do not prove it through mirror-based tests.



Meanwhile, wild baboon research highlights the role of age and temperament. Younger <a href="https://www.earth.com/news/humpback-whale-travels-farther-than-any-mammal-ever-recorded/" target="_blank" rel="noreferrer noopener">animals</a> showed more interest in new objects or stimuli, while older ones often lost curiosity fast, which might influence how they respond to novel visual scenarios.



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



Understanding how self-awareness varies across species can shift how people view intelligence and cognition in non-human animals. 



These mirror-based observations open deeper questions about whether awareness looks the same in every creature, given that some use their visual sense more than others.



Many anthropologists see such findings as a window into evolutionary processes that shape thinking and perception. Insights from field studies add a fresh dimension, since animals roam and behave naturally, away from the artificial conditions of captivity.



The mirror test has drawn <a href="https://www.theatlantic.com/science/archive/2023/04/fish-mirrors-animal-cognition-self-awareness-science/673718/">criticism</a> for its emphasis on the sense of sight. Yet, it remains a straightforward way to check if an animal perceives the reflection as an extension of itself.



The baboons gave scientists plenty to think about by investigating visible marks but ignoring those that only appeared in the mirror. Researchers plan to refine methods further and explore alternative signals of self-awareness out in the wild.



The study was published in the <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2024.1933" target="_blank" rel="noreferrer noopener">Proceedings of the Royal Society B: Biological Sciences</a>.

Wild baboons fail to recognize themselves in mirrors

Observers watching baboons in Namibia were impressed when they saw...

The world has long operated under the assumption that achieving climate goals would prevent the worst impacts of global warming, such as the melting of Arctic ice.



In 2016, nearly 200 world leaders committed to keeping global temperatures from rising beyond 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels. 



This agreement has shaped policies across nations, and driven efforts to cut emissions and transition toward cleaner energy.



Yet, despite those commitments, scientists now confirm that Earth's temperature increase crossed the 1.5-degree threshold in 2024. Not only has the planet <a href="https://www.earth.com/news/drastic-warming-will-transform-the-arctic-beyond-recognition/" target="_blank" rel="noreferrer noopener">warmed</a> faster than expected, but the changes already in motion cannot be undone.



The consequences are affecting every continent in a variety of ways, from intensifying storms to record-breaking heat waves.



<h2 class="wp-block-heading" id="h-paris-agreement-pledges">Paris Agreement pledges</h2>



A new study published in the journal Science reveals an even starker reality. If all countries follow through on their Paris Agreement pledges - which is a big assumption in itself - the planet is still on track to warm by an average of 2.7 degrees Celsius by the end of the century.



This level of warming will reshape economies, displace populations, and alter ecosystems in ways that humans have never before experienced.



"This is a reality check: we took a first step by signing the Paris Agreement, but we're already living in the 'changed world' we are attempting to prevent," noted Ted Schuur, a professor at <a href="https://nau.edu" target="_blank" rel="noreferrer noopener">Northern Arizona University</a>.



"It's time to take the next step to adjust our <a href="https://www.earth.com/news/arctic-warming-permafrost-melt-devastating-role-accelerating-global-climate-change/" target="_blank" rel="noreferrer noopener">climate goals</a> to accommodate this new reality."



<h2 class="wp-block-heading" id="h-arctic-s-role-in-accelerated-warming">Arctic's role in accelerated warming</h2>



One of the reasons the planet passed <a href="https://www.earth.com/news/costs-of-reversing-climate-change-multiply-after-a-tipping-point/" target="_blank" rel="noreferrer noopener">1.5 degrees of warming</a> so much sooner than expected lies far to the north. The Arctic, which once seemed distant and isolated, is now a central driver of climate shifts around the world.



Research shows that the Arctic is warming nearly four times faster than the rest of the planet. This is largely because ice, once a defining feature of the region, is disappearing at an alarming rate.



Sea ice, which used to form reliably every winter and partially melt in summer, is now melting at an accelerating pace. As more ice disappears, more of the ocean remains exposed.



<h2 class="wp-block-heading" id="h-warming-and-dark-arctic-waters">Warming and dark Arctic waters</h2>



Since dark ocean water absorbs more sunlight than white ice, this change amplifies the warming trend, creating a feedback loop that speeds up ice loss year after year.



"The <a href="https://www.earth.com/news/arctic-industrialization-how-will-it-impact-delicate-ecosystems/" target="_blank" rel="noreferrer noopener">Arctic</a> seas have already become unrecognizable," Schuur said. "The amount of ice we're left with at the end of the summer keeps declining over time. Soon enough, summer ice could become a thing of the past."



This transformation will have far-reaching consequences. <a href="https://www.earth.com/news/permafrost-is-no-longer-permanent-arctic-communities-in-danger/" target="_blank" rel="noreferrer noopener">Coastal Arctic communities</a> depend on sea ice for hunting, transportation, and protection from storm surges. 



As ice disappears, shipping routes will open, altering global trade patterns and potentially creating new geopolitical tensions.



<h2 class="wp-block-heading" id="h-thawing-permafrost-crisis">Thawing permafrost crisis</h2>



While melting sea ice is a visible reminder of climate change, another transformation is unfolding on land that is less obvious. 



Beneath the Arctic’s surface lies permafrost - frozen ground that has locked away massive amounts of carbon for thousands of years.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/02/arctic-meltdown_global-warming-acceleration_credit-Victor-Leshyk_1.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/02/arctic-meltdown_global-warming-acceleration_credit-Victor-Leshyk_1s.webp" alt="How 2.7 degrees of warming could accelerate permafrost thaw, ice melt and sea level rise in the Arctic.

Credit: Victor Leshyk</figcaption></figure>



As temperatures rise, this <a href="https://www.earth.com/news/thawing-permafrost-may-release-billions-of-tons-of-carbon-by-2100/" target="_blank" rel="noreferrer noopener">permafrost is thawing</a> and releasing carbon dioxide and methane into the atmosphere. 



These greenhouse gases intensify global warming, making it even harder to slow the planet’s temperature increase.



<h2 class="wp-block-heading" id="h-exponential-warming-acceleration">Exponential warming acceleration</h2>



Scientists estimate that, as this organic material decomposes, it will emit carbon at a rate that is comparable to that of industrialized nations.



Despite the scale of this threat, Schuur explained that policymakers in 2016 did not fully account for these Arctic-driven emissions.



"We're talking about a place that's remote to many people, but changes in the <a href="https://www.earth.com/news/the-arctic-may-be-ice-free-sooner-than-we-expected/" target="_blank" rel="noreferrer noopener">Arctic</a> don't stay in the Arctic," Schuur said.



The warming Arctic is shaping <a href="https://www.earth.com/news/arctic-warming-influences-us-weather-patterns-ai-machine-learning/" target="_blank" rel="noreferrer noopener">weather patterns worldwide</a>, intensifying droughts, and increasing the likelihood of wildfires worldwide.



The effects of permafrost thaw are already being felt far from the Arctic. Extreme heat events, like the 70 days of 110-degree temperatures in Phoenix last summer, are partially linked to these additional greenhouse gas emissions. 



<h2 class="wp-block-heading" id="h-how-arctic-warming-impacts-the-world">How Arctic warming impacts the world</h2>



The rapid transformation of the Arctic is not just an environmental issue - it is an economic and social challenge that will affect millions of people.



<a href="https://www.earth.com/news/sea-level-rise-will-cost-coastal-cities-over-1-trillion-in-damages/" target="_blank" rel="noreferrer noopener">Coastal cities</a>, which are already vulnerable to rising seas, will face even more frequent flooding as ice sheets continue to melt. 



Fisheries that support millions of livelihoods will struggle to adapt as <a href="https://www.earth.com/news/ocean-warming-broke-records-for-450-straight-days/" target="_blank" rel="noreferrer noopener">ocean temperatures</a> rise and ecosystems shift.



The disappearance of Arctic ice is also reshaping the world’s energy landscape. As previously unreachable oil and gas reserves become accessible, some countries may push to exploit these resources, potentially increasing <a href="https://www.earth.com/news/global-co2-emissions-rise-as-nations-tackle-fossil-fuel-dependence/" target="_blank" rel="noreferrer noopener">fossil fuel production</a> at a time when emissions need to be cut.



Schuur emphasized that the world must recognize this new reality and respond accordingly. The past assumption that global warming could be controlled easily is no longer valid.



The task ahead is twofold: adapt to the inevitable changes that are already happening and work to prevent the worst-case scenarios from unfolding.



<h2 class="wp-block-heading" id="h-preparing-for-an-unavoidable-future">Preparing for an unavoidable future</h2>



The latest projections show that, if current policies remain unchanged, the planet will warm by 2.7 degrees Celsius before 2100. 



That means there will be more extreme weather events, rising sea levels, and ecosystems pushed beyond their limits.



"We can't stop change from happening; it's already happening," Schuur said. "But we can slow the change by reducing <a href="https://www.earth.com/news/worlds-first-greenhouse-gas-detecting-satellite-is-now-in-orbit/" target="_blank" rel="noreferrer noopener">greenhouse gas emissions</a> and managing the change as best as we can so that people and ecosystems are better positioned for the future."



Governments must strengthen infrastructure, improve disaster preparedness, and develop climate-resistant agriculture. 



Individuals can push for policies that prioritize renewable energy, sustainable urban planning, and conservation efforts.



<h2 class="wp-block-heading" id="h-action-is-needed-at-every-level">Action is needed at every level</h2>



While global policies play a crucial role, local action can often have a more immediate <a href="https://www.earth.com/news/first-ice-free-day-in-the-arctic-may-arrive-in-2027/" target="_blank" rel="noreferrer noopener">impact</a> against Arctic warming. 



Schuur encouraged people to engage with their city, county, or state <a href="https://www.earth.com/news/sustainable-food-systems-are-gaining-momentum/" target="_blank" rel="noreferrer noopener">sustainability efforts</a>. Getting involved can mean attending meetings, proposing new policies, or supporting climate initiatives through voting.



Individual actions also matter. Choosing cleaner transportation, reducing energy use, and supporting businesses that prioritize sustainability all contribute to slowing climate change. 



These choices may not reverse <a href="https://www.earth.com/news/global-warming-is-accelerating-beyond-control-as-co2-levels-rise/" target="_blank" rel="noreferrer noopener">global warming</a>, but they can delay its effects and provide communities with more time to adapt.



"Don't give up, even in the face of change," Schuur said. "Instead, change your thinking. Say to yourself: I live in a new, changed world. What can I do to help adapt and slow the change so we have more time to adjust?"



The challenge ahead is immense, but action at every level - global, national, and local - will determine how well the world navigates this new era. 



The time for waiting has passed. Now is the moment to prepare for the world that is already here.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.ads1549" target="_blank" rel="noreferrer noopener">Science</a>.
