NASA’s Parker Solar Probe touched the Sun's atmosphere, flying within 3.8 million miles (around 6.1 million kilometers) from the surface of the Sun on Tuesday, Dec. 24, at 6:53 a.m. EST. 



During its closest approach, also called perihelion, mission operations will be out of contact with the spacecraft. 



Parker will transmit another beacon tone on Friday, Dec. 27, to confirm its health following the close flyby.



<h2 class="wp-block-heading" id="h-going-where-no-human-made-object-has-gone">Going where no human-made object has gone</h2>



This approach is unlike anything previously accomplished by a human-made spacecraft, marking a landmark in solar science that may rewrite much of what we know about our star.



Arik Posner, <a href="https://parkersolarprobe.jhuapl.edu/" target="_blank" rel="noreferrer noopener">Parker Solar Probe</a> program scientist at NASA Headquarters in Washington, sees this effort as a new window into solar research. “This is one example of NASA’s bold missions, doing something that no one else has ever done before to answer longstanding questions about our universe,” said <a href="https://science.nasa.gov/people/dr-arik-posner/" target="_blank" rel="noreferrer noopener">Arik</a>. The Johns Hopkins Applied Physics Laboratory (<a href="https://www.jhuapl.edu/" target="_blank" rel="noreferrer noopener">APL</a>) in Laurel, Maryland, manages mission operations and is keeping a watchful eye on every step as Parker speeds by.



<h2 class="wp-block-heading" id="h-breathtaking-pace-of-the-parker-solar-probe">Breathtaking pace of the Parker solar probe</h2>



The spacecraft is moving at approximately <a href="https://www.nasa.gov/feature/goddard/parker-solar-probe" target="_blank" rel="noreferrer noopener">430,000 miles per hour</a>. At that velocity, Parker could zip from New York to Los Angeles in about 20 seconds. 



By <a href="https://www.earth.com/news/parker-solar-probe-will-fly-through-suns-atmosphere-tomorrow-for-the-first-time/" target="_blank" rel="noreferrer noopener">approaching the Sun</a> so closely, mission teams hope to retrieve data that no earlier craft could access. Particles in the corona -- where temperatures can exceed a few million degrees -- tend to behave in puzzling ways. 



Scientists aim to see how these intense conditions might shape <a href="https://science.nasa.gov/sun/what-is-the-solar-wind/" target="_blank" rel="noreferrer noopener">solar wind</a>, which jets out at more than one million miles per hour.



Engineers designed Parker’s trajectory with careful flybys of Venus to shrink its orbit gradually around the Sun. This path has taken years to perfect since launch in 2018. 



Each loop demanded detailed calculations to ensure the craft can survive the approach, collect the right measurements, and keep sending updates back to Earth.



<h2 class="wp-block-heading" id="h-solar-probe-battling-extreme-heat">Solar probe battling extreme heat</h2>



Because the Sun’s heat is punishing at such a short distance, Parker Solar Probe relies on a <a href="https://parkersolarprobe.jhuapl.edu/Spacecraft/index.php#Extreme-Environments" target="_blank" rel="noreferrer noopener">carbon-composite shield</a> 4.5 inches thick.



This protective layer keeps sensitive instruments near room temperature while the shield’s front side can face extreme temperatures above 2,500 degrees Fahrenheit.



Sophisticated cooling systems also channel heat away from the core of the <a href="https://www.earth.com/news/meet-the-fastest-human-made-object-ever-nasas-parker-solar-probe/" target="_blank" rel="noreferrer noopener">spacecraft</a>, helping to sustain the electronics that record measurements of plasma, magnetic fields, and solar wind particles.



Inside, the instruments are scanning for clues to explain the corona’s unusual temperatures, which skyrocket to levels far higher than the Sun’s visible surface. 



Those same instruments are also watching for charged particle bursts and fluctuations in magnetic fields that might help answer big questions about what accelerates the solar wind.



<h2 class="wp-block-heading" id="h-crucial-timing-and-limited-contact">Crucial timing and limited contact</h2>



Today’s perihelion means Parker is currently skimming the outer atmosphere of the <a href="https://www.earth.com/news/solar-orbiter-spacecraft-sees-the-sun-through-three-different-lenses/" target="_blank" rel="noreferrer noopener">Sun</a> while in autonomous mode, out of immediate radio contact.



This window of silence is standard because powerful solar emissions prevent reliable communication. Mission operators anticipate a beacon tone on December 27, which should confirm Parker has survived.



Scientists believe that data from this flyby could provide <a href="https://www.earth.com/news/parker-solar-probe-will-fly-through-suns-atmosphere-tomorrow-for-the-first-time/" target="_blank" rel="noreferrer noopener">unprecedented detail on solar activity</a>. Periods of heightened activity, known as solar maxima, produce more flares and coronal mass ejections. These events can spawn auroras at unexpected latitudes and threaten satellites with bursts of charged particles. 



By collecting data from close range, Parker might reveal new insights into how these explosive happenings form and evolve.



<h2 class="wp-block-heading" id="h-visionary-behind-the-parker-solar-probe">Visionary behind the Parker solar probe</h2>



This trailblazer of solar research is named after <a href="https://news.uchicago.edu/story/eugene-parker-legendary-figure-solar-science-and-namesake-parker-solar-probe-1927-2022" target="_blank" rel="noreferrer noopener">Dr. Eugene N. Parker</a>, the late astrophysicist from the University of Chicago who proposed the existence of the solar wind back in the 1950s.



He changed our understanding of how stars interact with their surroundings. In 2018, he became the first person to witness the launch of a spacecraft bearing his name. 



Though he passed away in 2022, his legacy lives on in every close pass the probe completes.



<h2 class="wp-block-heading" id="h-a-closer-look-at-solar-wind">A closer look at solar wind</h2>



One of the main motivations behind Parker Solar Probe mission is to figure out how <a href="https://www.earth.com/news/strong-solar-storm-warning-issued-as-two-cmes-will-hit-earth-tomorrow/" target="_blank" rel="noreferrer noopener">solar wind</a>, that stream of charged particles racing from the Sun, accelerates to incredible speeds. Scientists hope Parker will pinpoint where and how energy is transferred to these particles. Such information could refine space weather forecasts, which are critical for protecting satellites, power grids, and astronauts in orbit.



<a href="https://www.plasmacoalition.org/plasma_writeups/solar_plasmas.pdf" target="_blank" rel="noreferrer noopener">Plasma</a> behavior at these altitudes can also inform theories about stellar physics beyond the Sun. 



Many stars release similar particle streams, so unraveling the inner workings of the solar wind could offer a template for understanding events happening light-years away.



<h2 class="wp-block-heading" id="h-high-stakes-data-for-space-weather-predictions">High-stakes data for space weather predictions</h2>



Operators know that space weather can have major effects here on Earth. Sudden geomagnetic storms have been known to disrupt radio signals, damage satellites, and even cause power outages. By studying the Sun’s activity from the inside, Parker could lead to more accurate warnings for regions of the world vulnerable to blackouts. 



Air traffic, GPS services, and communication infrastructure may all benefit from improved predictions of <a href="https://science.nasa.gov/science-research/heliophysics/space-weather/solar-flares/what-is-a-solar-flare/" target="_blank" rel="noreferrer noopener">solar flares</a> and <a href="https://www.swpc.noaa.gov/phenomena/solar-radiation-storm#:~:text=Solar%20radiation%20storms%20occur%20when,of%20the%20speed%20of%20light." target="_blank" rel="noreferrer noopener">particle storms</a>.



<h2 class="wp-block-heading" id="h-a-milestone-for-parker-solar-probe">A milestone for Parker Solar Probe</h2>



Now that the probe is at perihelion, mission managers will hold their breath for a few days.



“No human-made object has ever passed this close to a star, so Parker will truly be returning data from uncharted territory,” explained <a href="https://parkersolarprobe.jhuapl.edu/News-Center/Show-Article.php?articleID=205" target="_blank" rel="noreferrer noopener">Nick Pinkine</a>, Parker Solar Probe mission operations manager at <a href="https://www.jhuapl.edu/" target="_blank" rel="noreferrer noopener">APL</a>. 



He added that the team is eager to see how Parker managed the flyby when the link reopens.



This moment is a milestone for solar science. If everything goes as planned, Parker will maintain its orbit for future close passes, each offering a renewed chance to investigate the corona’s strange properties.



Researchers anticipate more discoveries that will fill in knowledge gaps about the Sun’s extreme environment.



Far from being an isolated phenomenon, the Sun’s behavior plays a significant role in shaping conditions on Earth. 



Today’s brush with solar fury signals the continuing progress of human exploration -- and the promise of deeper insight into the star that illuminates our world.

Mission accomplished? Solar Probe just touched the Sun, but we don't know if it survived

NASA’s Parker Solar Probe touched the Sun's atmosphere, flying within...

Star formation takes center stage this holiday season as space telescopes unveil breathtaking images of stellar nurseries. Among these discoveries is a dazzling star cluster known as NGC 602, which resembles a festive wreath floating in the cosmos.



Made up of stars, dust, and cosmic gases, this celestial formation offers not only visual splendor but also a unique opportunity to study the processes that shaped the early universe. 



Scientists at NASA and the Smithsonian Astrophysical Observatory combined data from the Chandra X-ray Observatory and the James Webb Space Telescope to reveal the intricate details of this stunning cluster that is nestled within the <a href="https://www.earth.com/image/open-star-cluster-in-the-small-magellanic-cloud/" target="_blank" rel="noreferrer noopener">Small Magellanic Cloud</a>, a neighboring galaxy located 200,000 light-years away.



<h2 class="wp-block-heading" id="h-a-natural-laboratory-for-star-formation">A natural laboratory for star formation</h2>



This cosmic wreath isn't just pretty to look at - it's a treasure trove of scientific insights that teaches us about the intricate processes behind <a href="https://www.earth.com/news/serpens-nebula-image-reveals-how-stars-are-born/" target="_blank" rel="noreferrer noopener">how stars are born</a> and develop over time.



The stars in NGC 602, with their significantly lower heavy element content (when compared to our Sun), closely resemble the <a href="https://www.earth.com/news/ancient-stars-shakti-shiva-shaped-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">ancient stars</a> that existed billions of years ago in the early universe.



This unique characteristic makes the cluster an unparalleled natural laboratory for astronomers, allowing them to study early star formation under conditions that mirror those of a much younger cosmos.



<h2 class="wp-block-heading" id="h-cosmic-wreath-made-of-stars">Cosmic wreath made of stars</h2>



The wreath shape comes from dense clouds of dust that are visible in the Webb telescope data as orange, yellow, green, and blue colors.



The <a href="https://chandra.harvard.edu/" target="_blank" rel="noreferrer noopener">Chandra X-ray Observatory</a> adds another layer to our view, showing young, massive stars in red. 



These stars send powerful winds and high-energy light into space, creating an extended cloud that glows with X-rays from thousands of young, low-mass stars.



<h2 class="wp-block-heading" id="h-holiday-double-feature-the-christmas-tree-cluster">Holiday double feature: The Christmas tree cluster</h2>



The <a href="https://www.earth.com/news/new-telescopes-can-directly-detect-signs-of-alien-life-in-exoplanet-atmospheres/" target="_blank" rel="noreferrer noopener">space telescopes</a> didn't stop with the festive wreath visual. They also captured fresh images of NGC 2264, which is nicknamed the "<a href="https://www.earth.com/news/cosmic-christmas-tree-captured-by-nasas-chandra-observatory/" target="_blank" rel="noreferrer noopener">Christmas Tree Cluster</a>."



This stellar grouping is much closer to Earth - just 2,500 light-years away - and contains stars that are between one and five million years old.



To put that in perspective, these stars are babies compared to our sun, which is about 5 billion years old.



The new view of NGC 2264 combines Chandra's X-ray data (shown in red, purple, blue, and white) with optical observations in green and violet. 



These optical images were taken by astrophotographer Michael Clow using his telescope in Arizona in November 2024.



<h2 class="wp-block-heading" id="h-the-technology-behind-the-discovery">The technology behind the discovery</h2>



These observations showcase the power of combining different types of telescopes. 



While the Chandra X-ray Observatory operates under NASA's Marshall Space Flight Center in Huntsville, Alabama, its science operations are managed by the Chandra X-ray Center in Cambridge, Massachusetts, with flight operations running from Burlington, Massachusetts.



These stellar formations remind us that, even in the cold vastness of space, we can find familiar shapes that connect with our human experience and help us understand the universe around us.



<h2 class="wp-block-heading" id="h-star-formation-and-evolving-galaxies">Star formation and evolving galaxies</h2>



Star formation is one of the most&nbsp;basic&nbsp;processes&nbsp;for astronomers to understand. It is this process that helps shape evolving galaxies.



Stars are&nbsp;formed&nbsp;in dense clouds of gas and dust, commonly&nbsp;referred to as stellar nurseries, where gravitational forces cause the materials to collapse and instigate nuclear fusion in their cores.



This process not only&nbsp;produces&nbsp;light and heat but also forges the&nbsp;heavy elements that will become building blocks for planets and life itself.



By studying star formation in clusters like NGC 602, scientists can trace the cosmic history of element creation and distribution throughout the universe. 



Observing these processes in regions with varying conditions, such as low-metallicity environments, allows astronomers to refine their models of how stars form, evolve, and influence their surroundings over time.



All&nbsp;this&nbsp;helps&nbsp;in&nbsp;understanding&nbsp;how, during their life cycles, the&nbsp;stars&nbsp;evolve&nbsp;into supernovae, black holes, or neutron stars and assume&nbsp;a&nbsp;very&nbsp;important&nbsp;role in the dynamic interplay of cosmic forces.



<h2 class="wp-block-heading" id="h-broader-implications-of-the-research">Broader implications of the research </h2>



The insights gained from such research go beyond astronomy, influencing other scientific fields like physics and chemistry. 



Understanding how stars and their planetary systems develop can even inform our search for life on other worlds. 



Star formation, therefore, is not just about the birth of stars - it’s a key to unlocking the broader story of the universe itself.

Dazzling star cluster creates a cosmic holiday wreath

Star formation takes center stage this holiday season as space...

Picture a landscape on Mars where frost covers the ground, and the crisp sound of icy surfaces breaking underfoot fills the air. Above, sunlight filters through clouds mixed with ice and dust, creating a warm, golden glow. This is the Australe Scopuli region, located at the southern pole of Mars.



It offers a striking contrast - its alien features are shaped by the Red Planet's unique environment, yet its serene beauty evokes scenes that feel almost Earth-like.



This blend of the otherworldly and the familiar makes it a captivating subject for scientific exploration and visual fascination.



<h2 class="wp-block-heading" id="h-australe-scopuli-unique-polar-landscape-on-mars">Australe Scopuli: Unique polar landscape on Mars</h2>



The High Resolution Stereo Camera (HRSC) aboard the&nbsp;<a href="https://www.esa.int/Science_Exploration/Space_Science/Mars_Express" target="_blank" rel="noreferrer noopener">Mars Express</a>&nbsp;captured stunning images of Australe Scopuli, displaying its distinctive polar deposits.



This region lies near the "cryptic terrain," a puzzling area previously explored by few scientists. Here, layers of carbon dioxide ice and dust swirl together, creating a white, frosty terrain that contrasts sharply with the iconic red <a href="https://www.earth.com/news/how-mars-became-uninhabitable-after-being-life-supporting-ocean-world/" target="_blank" rel="noreferrer noopener">Martian soil</a>.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_frost_ice_Mars-Express_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_frost_ice_Mars-Express_1s.webp" alt="Swirls of light and dark layers mark the boundaries between ice and dust layers exposed in this icy scene from the Australe Scopuli region of Mars.

These layered polar deposits result from seasonal cycles, with ice forming and trapping varying amounts of dust. 



The contrasting light and dark layers are particularly visible on hills and in valleys, painting the landscape with striking textures.



When viewed through 3D glasses, the region’s topography resembles Earthly ski resorts, with smooth slopes, sharp turns, and steep hillsides.



But skiing on Mars would require preparation for extreme cold: temperatures here plunge to a bone-chilling -125°C (-193°F).



<h2 class="wp-block-heading" id="h-changing-seasons-and-martian-spiders">Changing seasons and Martian "spiders"</h2>



The images, taken on June 16, 2022, during the <a href="https://www.earth.com/news/hidden-water-found-on-mars-would-cover-the-planet-over-one-mile-deep/" target="_blank" rel="noreferrer noopener">Martian</a> summer solstice, showcase how Mars’s southern pole transitions with the changing seasons.



Dark patches in the imagery reveal areas where carbon dioxide ice has sublimated, a process where the ice turns directly from solid to vapor without melting.



This sublimation is driven by sunlight, which warms the ice. As the ice evaporates, it leaves behind trails of dark dust spread across the surface. 



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_perspective_Mars-Express_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_perspective_Mars-Express_1s.webp" alt="Perspective view across undulating terrain at the Australe Scopuli region of Mars, with exposed layers of ice and dust.

Numerous dark dusty fan-shaped features follow the pattern of the layers. Credit: Mars Express/ESA</figcaption></figure>



These fan-shaped patterns, sculpted by prevailing winds, provide a remarkable look at the seasonal dynamics in <a href="https://www.earth.com/news/mars-gravity-pulls-earth-closer-to-the-sun-warming-our-climate-scientists-say/" target="_blank" rel="noreferrer noopener">Mars</a>'s polar regions.



As summer progresses, sunlight penetrates the translucent carbon dioxide ice, heating the ground beneath it. This leads to the formation of gas pockets as the underlying ice sublimates. 



When the gas pressure becomes too high, the ice cracks, releasing bursts of gas and dust into the atmosphere. These jets create fan-shaped deposits that can stretch for hundreds of meters.



This process resembles the formation of <a href="https://www.earth.com/news/marss-space-debris-should-be-regarded-as-historical-artifacts/" target="_blank" rel="noreferrer noopener">Martian</a> "spiders," another fascinating feature observed in recent&nbsp;Mars Express imagery, where similar sublimation mechanisms create spider-like patterns on the surface.



<h2 class="wp-block-heading" id="h-dynamic-australe-scopuli-of-mars">Dynamic Australe Scopuli of Mars</h2>



A detailed look at Australe Scopuli shows that the dust jets typically emerge along the edges of layered polar deposits. These boundaries may act as fragile zones, allowing the jets to break through with less resistance.



This phenomenon, shaped by seasonal temperature changes and the region’s topography, creates a dynamic and evolving <a href="https://www.earth.com/news/air-samples-from-mars-could-reveal-fascinating-secrets/" target="_blank" rel="noreferrer noopener">Martian</a> landscape. 



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_topography_Mars-Express_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/12/mars_south-pole_Australe-Scopuli-region_topography_Mars-Express_1s.webp" alt="A topography map of Australe Scopuli region of Mars color-coded according to relative heights.

The interplay between the shifting ice and dust patterns highlights the complexity of Mars’s natural processes.



Although building a snowman on Mars might not be possible, the Australe Scopuli region captures the essence of the planet’s unique beauty. 



It offers scientists and explorers a fascinating glimpse into the changing polar environment of the Red Planet.



<h2 class="wp-block-heading" id="h-science-behind-the-images">Science behind the images</h2>



The HRSC on&nbsp;Mars Express&nbsp;is a remarkable piece of engineering, designed and developed by the German Aerospace Center (DLR).



After the camera captured detailed images of Mars, the <a href="https://www.dlr.de/en/pf/about-us/departments" target="_blank" rel="noreferrer noopener">DLR Institute for Planetary Research</a> in Berlin-Adlershof processed the data. 



Using this data, the Planetary Science and Remote Sensing group at <a href="https://www.fu-berlin.de/en/index.html" target="_blank" rel="noreferrer noopener">Freie Universität Berlin</a> created the stunning final images we see today.



In conclusion, the images of Australe Scopuli offer much more than just stunning visuals of the Martian southern pole. 



They serve as powerful proof of the intricate and ever-changing processes that sculpt the Red Planet's icy polar regions.



Every layer of ice and dust preserved in these photographs tells a unique story about <a href="https://www.earth.com/news/mars-curiosity-rover-makes-surprising-find-under-martian-rock-sulfur-crystals/" target="_blank" rel="noreferrer noopener">Mars</a>'s geological and climatic history. 



By studying these features in detail, researchers can piece together the planet's evolving climate and uncover the mysteries of its geological past.

White Christmas on Mars and its changing polar landscapes

Picture a landscape on Mars where frost covers the ground,...

Santa,Claus,Sitting,Near,The,Fireplace,And,Christmas,Tree,With

Every December, colorful lights and festive tunes remind kids, and adults, that Santa Claus is on his way. Families fill their homes with decorations, children write wish lists, and a sense of anticipation hangs in the air. 



Parents have long told their kids that if they behave well, Santa will bring them just what they asked for. Until recently, few studies examined whether this belief actually influenced how kids act.



In a new project, researchers decided to see if <a href="https://www.earth.com/news/irregular-bedtimes-disrupt-the-well-being-and-behavior-of-children/" target="_blank" rel="noreferrer noopener">children</a> truly become more considerate when they think Santa is watching. 



They explored whether kids act better because of the story of Santa or because of everything else going on during the holiday season. 



Professor Kapitány from the <a href="https://www.ox.ac.uk/" target="_blank" rel="noreferrer noopener">University of Oxford</a> led the investigation along with colleagues from <a href="https://www.durham.ac.uk/" target="_blank" rel="noreferrer noopener">Durham</a>, <a href="https://www.ed.ac.uk/" target="_blank" rel="noreferrer noopener">Edinburgh</a>, and <a href="https://www.leeds.ac.uk/" target="_blank" rel="noreferrer noopener">Leeds</a>.



<h2 class="wp-block-heading" id="h-kids-santa-and-surprises">Kids, Santa, and surprises</h2>



The study tracked 533 kids between ages four and nine over three separate Christmases and visits from Santa. Families <a href="https://www.earth.com/news/kids-with-behavioral-issues-have-high-cortisol-levels-in-their-hair/" target="_blank" rel="noreferrer noopener">reported on behaviors</a> like sharing, helping others, and following rules. 



Parents also described whether their kids believed in Santa and took part in festive traditions. According to the data, there was no direct link between Santa belief alone and an increase in kindness.



Instead, good behavior rose as Christmas neared when families engaged in activities such as decorating their homes, singing carols, and enjoying special treats.&nbsp;



The study noted that these experiences led to small but consistent boosts in generous and <a href="https://www.earth.com/news/kindergarten-conduct-childhood-behavioral-problems-will-cost-society-later/" target="_blank" rel="noreferrer noopener">respectful actions</a>. 



This shift also came with a bump in more rowdy moments, highlighting that heightened excitement can show up in many ways.



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



For many families, hanging ornaments or baking Christmas cookies is more than just a fun holiday pastime. 



These rituals offer children a chance to feel a sense of togetherness and excitement that breaks up their usual routine. 



The study suggests that these shared activities have a greater <a href="https://www.earth.com/news/children-consider-their-own-past-actions-before-judging-others/" target="_blank" rel="noreferrer noopener">effect on kindness</a> than the idea of being judged by a mysterious gift-giver in a red suit.



Parents often say they remind kids to be on their best behavior so Santa will reward them. Yet the findings show it’s the holiday atmosphere itself that has the strongest pull. 



One researcher described it by saying “the magic is in the time of year, so to speak, not in the claim over the supernatural big man.”



<h2 class="wp-block-heading" id="h-supernatural-beliefs-and-morality">Supernatural beliefs and morality</h2>



Some scholars point out that Santa is often placed on the same pedestal as other powerful beings in certain cultures. 



Parents treat him as a figure who can watch children from afar, keep track of good deeds, and decide on gifts. 



This study adds to conversations about how belief in unseen forces might shape moral choices.



Other work shows that religious ideas can sometimes bring out prosocial behavior. Hearing about rules or promises of rewards can prompt more cooperation.&nbsp;



In the case of Santa, though, the results suggest that the presence of traditions might play a bigger role in guiding kids toward friendly, generous actions.



<h2 class="wp-block-heading" id="h-contrasting-philosophies-on-kids-and-santa">Contrasting philosophies on kids and Santa</h2>



Philosophers have different views on whether parents should even promote Santa’s story. 



Dr. Joseph Millum from the <a href="https://www.st-andrews.ac.uk/" target="_blank" rel="noreferrer noopener">University of St. Andrews</a> worries it “breaches trust,” calling Santa a “preposterous lie.” Others feel that Santa can be a healthy way to bring joy into children’s lives. 



Tom Whyman, a lecturer in philosophy at the <a href="https://www.liverpool.ac.uk/" target="_blank" rel="noreferrer noopener">University of Liverpool</a>, says that “kids need Santa.” 



These opinions highlight the varying attitudes people have toward a figure whose influence has become an enduring feature of holiday culture.



When parents choose whether to encourage this tale, they grapple with how it shapes their children’s sense of wonder and truth. 



Some families see Santa as <a href="https://www.earth.com/news/pretend-play-builds-the-foundation-for-learning-and-relationships/" target="_blank" rel="noreferrer noopener">harmless make-believe</a>, while others wonder if creating a magical visitor might later undermine a child’s trust. 



The study reminds us that cultural myths carry weight, yet they may not fully explain shifts in children’s behavior.



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



The research shows that singing festive songs, <a href="https://www.earth.com/news/christmas-trees-have-unique-strategies-to-survive-freezing-winters/" target="_blank" rel="noreferrer noopener">placing ornaments on a tree</a>, or preparing traditional foods creates a distinct environment. That environment is linked with both extra kindness and occasional bursts of negative behavior. 



While the belief in Santa himself did not correlate directly with improved conduct, the coordinated celebration of the season proved to be more powerful.



Families can consider how these moments <a href="https://www.earth.com/news/personality-traits-are-not-strongly-inherited-from-parents/" target="_blank" rel="noreferrer noopener">bring the household closer</a>. Children who help bake cookies or watch a classic Christmas movie often feel a greater sense of involvement. 



This sense of participation aligns with the study’s findings that holiday events can be a driving force behind thoughtful gestures, cooperation, and cheer.



<h2 class="wp-block-heading" id="h-bigger-questions-about-childhood-and-culture">Bigger questions about childhood and culture</h2>



Santa’s modern image traces back to a blend of folklore, marketing campaigns, and traditions inspired by Saint Nicholas. 



For countless children, the idea of a kindhearted figure traveling the skies in a single night is a highlight of December. 



This study encourages us to think about how such stories fit into broader questions about parenting approaches and cultural myths. 



Many communities celebrate special figures who reward the nice and ignore or punish the naughty. 



In each case, children experience stories they can hold onto, if only for a few magical years. The current research suggests that these stories may matter less than the rituals and music, but they still add color to the season.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



Plenty of families continue to share the Santa story, watch Christmas movies, and maintain lively traditions. 



The researchers point out that more studies could explore how different cultural celebrations, and the potential <a href="https://www.earth.com/news/holiday-stress-is-higher-this-year-compared-to-2023/" target="_blank" rel="noreferrer noopener">stress levels surrounding them</a>, ultimately help shape child development. 



From the outside, it might seem obvious that gatherings, songs, and decorations encourage bright and kind behavior, yet measuring these elements takes careful planning.



Some psychologists are curious about whether similar patterns show up around other holidays or special events with strong rituals.&nbsp;



The core message remains that communal practices, family bonding, and joyful anticipation often spark gentler and more considerate behavior in children. 



The Santa myth is part of that puzzle, but it may not be the only factor making kids play nicely.



<h2 class="wp-block-heading" id="h-what-did-we-learn-about-kids-and-santa">What did we learn about kids and Santa?</h2>



The takeaway here is that Christmas is a powerful backdrop for <a href="https://www.earth.com/news/many-parents-use-threats-to-discipline-children-but-its-not-effective-in-the-long-run/" target="_blank" rel="noreferrer noopener">shaping how children behave</a>. 



A lively household filled with festive foods, carols, and colorful decorations can steer kids toward more thoughtful choices, even if the well-known Santa story doesn’t stand alone as a motivator. 



Traditions that families share appear to matter more than the promise of presents under the tree.



These observations offer a new way to think about how myths and rituals come together to create a meaningful holiday experience.&nbsp;



Children may still look forward to Santa’s arrival each year, but the real spark for positive behavior lies in those precious moments spent enjoying the season.

Does believing in Santa really make kids behave better? A new study found out

Every December, colorful lights and festive tunes remind kids, and...

The solar system, billions of years old, holds many secrets about its formation. Among its fascinating residents is Chiron, a centaur orbiting between Jupiter and Neptune. 



New findings by scientists using the James Webb Space Telescope (JWST) shed light on this hybrid of comet and asteroid, revealing unprecedented insights into its surface chemistry and activity.



The study was led by Dr. Noemí Pinilla-Alonso of the University of Oviedo and Dr. Charles Schambeau from the University of Central Florida (UCF). Their findings could reshape our understanding of centaurs and the solar system’s early history.



<h2 class="wp-block-heading" id="h-time-capsules-of-the-solar-system">Time capsules of the solar system </h2>



<a href="https://www.earth.com/news/deep-space-objects-called-centaurs-29p-continue-to-perplex-nasa/" target="_blank" rel="noreferrer noopener">Centaurs</a> are objects with dual characteristics, straddling the line between asteroids and comets. 



Chiron, discovered in 1977, is unique even among centaurs. It exhibits comet-like behavior, including a coma - a cloud of gas and dust - alongside distinct surface and interior features.



Dr. Pinilla-Alonso emphasizes that centaurs act as “time capsules,” preserving information about the solar system’s formation. "All small bodies in the solar system talk to us about how it was back in time,” she explained. 



Chiron’s activity, driven by solar heating, offers a rare opportunity to explore these preserved secrets.



<h2 class="wp-block-heading" id="h-unprecedented-chemical-diversity-in-a-centaur">Unprecedented chemical diversity in a centaur</h2>



Using <a href="https://science.nasa.gov/mission/webb/" target="_blank" rel="noreferrer noopener">JWST</a>, the team discovered that Chiron's surface hosts carbon dioxide and carbon monoxide ice. Its coma contains methane and other gases, marking the first detection of such diversity in a centaur. 



“These results are like nothing we’ve seen before,” noted Dr. Schambeau from <a href="https://www.ucf.edu/" target="_blank" rel="noreferrer noopener">UCF</a>.



JWST’s advanced capabilities allowed the researchers to study Chiron even at its farthest point from the Sun. This distance usually limits the activity of similar objects, such as trans-Neptunian objects (TNOs).



Unlike <a href="https://www.earth.com/news/comet-will-be-visible-for-the-first-time-in-50000-years/" target="_blank" rel="noreferrer noopener">comets</a> closer to the Sun, Chiron’s thinner coma offers clearer insights into its surface chemistry.



<h2 class="wp-block-heading" id="h-chiron-s-ice-and-gas-dynamics">Chiron's ice and gas dynamics</h2>



Dr. Pinilla-Alonso noted that Chiron’s dual nature makes it invaluable for studying processes in both comets and <a href="https://www.earth.com/news/two-large-asteroids-will-pass-near-earth-this-week/" target="_blank" rel="noreferrer noopener">asteroids</a>. 



"What is unique about Chiron is that we can observe both the surface and the coma,” she said.



This dual observation provides critical information about the ice layer's thickness, porosity, and chemical properties.

JWST’s observations revealed the coexistence of primordial ices, such as methane and water, and newer compounds formed through surface processes. 



“Every active centaur we observe shows some peculiarity,” said Dr. Pinilla-Alonso. Understanding these peculiarities may uncover patterns across these <a href="https://www.earth.com/news/once-in-a-lifetime-comet-will-be-easily-visible-this-month/" target="_blank" rel="noreferrer noopener">enigmatic objects</a>.



<h2 class="wp-block-heading" id="h-an-oddball-among-centaurs">An oddball among centaurs</h2>



Chiron stands out due to its unusual behavior, including comet-like activity and potential rings of debris. 



Dr. Schambeau describes it as “an oddball” with a unique thermophysical process. He analyzed methane in Chiron’s coma, linking its outflow to sun-heated regions on its surface.



These findings deepen our understanding of <a href="https://www.earth.com/wp-content/uploads/2024/12/2060-chiron_debris-disk_asteroid-comet-hybrid_credit-USF_1big.jpg" target="_blank" rel="noreferrer noopener">centaurs’ evolution and behavior</a>. 



Chiron’s dynamic environment provides clues about how solar heating influences its surface and subsurface, offering a glimpse into processes shaping similar bodies.



<h2 class="wp-block-heading" id="h-origins-and-future-of-chiron">Origins and future of Chiron</h2>



Chiron likely originated in the TNO region before moving into its current orbit. Gravitational interactions with giant planets alter the paths of centaurs, exposing them to varied environments.



Dr. Pinilla-Alonso explained that centaurs typically remain in the giant planets’ region for about a million years before being ejected. “They may end their lives as Jupiter Family comets or return to the TNOs region."



Chiron’s journey across the solar system exposes it to solar radiation, driving surface changes and creating its unique chemical composition. 



Understanding this evolution provides valuable insights into the early solar system.



<h2 class="wp-block-heading" id="h-broader-implications-of-chiron-s-discovery">Broader implications of Chiron’s discovery</h2>



The study’s implications extend beyond Chiron. Identifying gases and ices on distant objects enhances our understanding of the solar system’s building blocks. 



These findings could also inform future research on centaurs and other icy bodies.



Dr. Pinilla-Alonso noted that JWST’s spectra revealed intricate details about Chiron’s ices and their interactions. "Based on our new JWST data, I’m not so sure we have a standard centaur."



Further studies may uncover shared traits among centaurs, offering a clearer picture of their origins and diversity.



<h2 class="wp-block-heading" id="h-learning-more-about-centaurs">Learning more about centaurs</h2>



The researchers from <a href="https://www.uniovi.es" target="_blank" rel="noreferrer noopener">University of Oviedo</a> and UCF plan to continue observing Chiron as it approaches the Sun.



Closer proximity will enable more detailed studies of its surface and coma, potentially uncovering new chemical and physical properties.



Future research may also explore seasonal variations and illumination effects on Chiron’s ice reservoir. Such studies could refine our understanding of how centaurs interact with their environments and evolve over time.



<h2 class="wp-block-heading" id="h-unveiling-the-mysteries-of-the-solar-system">Unveiling the mysteries of the solar system</h2>



The JWST, an international collaboration led by NASA, has revolutionized space science. 



Its ability to observe distant objects like Chiron is solving long-standing mysteries about the solar system and beyond. These discoveries highlight the telescope’s transformative impact on planetary science.



“JWST has made these detections accessible. These results enhance our understanding of Chiron’s interior composition and its unique behaviors,” concluded Dr. Schambeau.



<h2 class="wp-block-heading" id="h-new-chapter-in-solar-system-exploration">New chapter in solar system exploration</h2>



Chiron’s unique chemistry and activity mark a significant milestone in understanding the solar system’s origins. 



The ongoing research, powered by JWST’s capabilities, promises to unravel more secrets about this enigmatic centaur and its <a href="https://www.earth.com/news/its-official-earth-now-has-two-moons-captured-asteroid-2024-pt5/" target="_blank" rel="noreferrer noopener">counterparts</a>.



Through Chiron, scientists are not just uncovering the past - they are laying the groundwork for future exploration of icy bodies across the solar system.



“The analysis of Chiron’s gases and ices opens new frontiers and opportunities for exciting research,” said Dr. Pinilla-Alonso.
