These dark, starless worlds may have had stable oceans for billions of years — long enough for complex life to potentially emerge. Fri, 29 May 2026 02:05:08 EDT https://www.sciencedaily.com/releases/2026/05/260528082509.htm https://www.sciencedaily.com/releases/2026/05/260527023212.htm A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed. Wed, 27 May 2026 06:24:22 EDT https://www.sciencedaily.com/releases/2026/05/260527023212.htm https://www.sciencedaily.com/releases/2026/05/260525000455.htm Scientists believe a dust-filled ring just outside Jupiter acted like a cosmic “planetesimal factory,” producing multiple generations of early space rocks with very different compositions. The discovery may finally explain the origins of several mysterious meteorite types that have survived since the birth of the Solar System. Tue, 26 May 2026 01:48:02 EDT https://www.sciencedaily.com/releases/2026/05/260525000455.htm https://www.sciencedaily.com/releases/2026/05/260522023120.htm NASA scientists were stunned when a strange radio signal from the Sun refused to fade away. Instead of lasting a few hours or days like normal solar radio bursts, this one persisted for an astonishing 19 days — shattering the previous record. Using a fleet of spacecraft spread across the solar system, researchers tracked the mysterious signal to a massive magnetic structure on the Sun called a helmet streamer. Sat, 23 May 2026 08:06:50 EDT https://www.sciencedaily.com/releases/2026/05/260522023120.htm https://www.sciencedaily.com/releases/2026/05/260521072359.htm Mysterious red auroras spotted over Japan were found reaching astonishingly high altitudes, even during space storms considered relatively mild. The discovery suggests hidden solar activity may be stronger than scientists realized — with potential consequences for satellites orbiting Earth. Thu, 21 May 2026 23:02:27 EDT https://www.sciencedaily.com/releases/2026/05/260521072359.htm https://www.sciencedaily.com/releases/2026/05/260521072355.htm Astronomers using NASA’s James Webb Space Telescope have uncovered a rare world unlike anything in our solar system — a giant planet about the size of Saturn with surprisingly Earth-like temperatures and an atmosphere packed with methane. The planet, TOI-199b, sits more than 330 light-years away and is one of the first known “temperate” gas giants ever studied in detail. Thu, 21 May 2026 22:41:53 EDT https://www.sciencedaily.com/releases/2026/05/260521072355.htm https://www.sciencedaily.com/releases/2026/05/260520093753.htm Scientists have discovered a bizarre planetary system where a rocky world orbits farther out than giant gas planets, defying long-standing theories of planet formation. The finding hints that some planets may form much later than expected — and that our Solar System might not be as typical as we thought. Thu, 21 May 2026 02:09:31 EDT https://www.sciencedaily.com/releases/2026/05/260520093753.htm https://www.sciencedaily.com/releases/2026/05/260515002130.htm NASA’s Roman Space Telescope could expose a vast hidden population of neutron stars lurking unseen across the Milky Way. By detecting subtle shifts in starlight caused by gravity, the mission may identify and even weigh isolated neutron stars that are otherwise impossible to see. Scientists hope the discoveries will reveal how these extreme objects are born and why they are blasted through space at incredible speeds. Fri, 15 May 2026 03:33:51 EDT https://www.sciencedaily.com/releases/2026/05/260515002130.htm https://www.sciencedaily.com/releases/2026/05/260513221818.htm Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations. The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE. The findings suggest the Sun was far more active at the time, with unusually short solar cycles. Thu, 14 May 2026 01:55:09 EDT https://www.sciencedaily.com/releases/2026/05/260513221818.htm https://www.sciencedaily.com/releases/2026/05/260511213151.htm Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before. Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side. The disk contains enough material to potentially create multiple giant planets, making it a fascinating new laboratory for studying how planetary systems are born. Tue, 12 May 2026 00:42:10 EDT https://www.sciencedaily.com/releases/2026/05/260511213151.htm https://www.sciencedaily.com/releases/2026/05/260508003117.htm A mysterious comet from beyond our solar system is giving astronomers a rare glimpse into alien worlds — and it may have formed in a place far colder and stranger than anything around our Sun. The interstellar visitor, called 3I/ATLAS, contains an astonishingly high amount of “heavy water,” far exceeding anything seen in our own solar system. Fri, 08 May 2026 02:25:28 EDT https://www.sciencedaily.com/releases/2026/05/260508003117.htm https://www.sciencedaily.com/releases/2026/05/260508003115.htm The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated smashups inside incredibly crowded star clusters. These violent chain reactions appear to create a distinct class of rapidly spinning black holes that stand apart from ordinary ones formed by dying stars. Fri, 08 May 2026 02:16:10 EDT https://www.sciencedaily.com/releases/2026/05/260508003115.htm https://www.sciencedaily.com/releases/2026/05/260506225132.htm A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked even closer to the star, a setup once thought nearly impossible. Thu, 07 May 2026 16:53:58 EDT https://www.sciencedaily.com/releases/2026/05/260506225132.htm https://www.sciencedaily.com/releases/2026/05/260504154012.htm A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets. Using the James Webb Space Telescope, researchers studied LHS 3844 b—a tidally locked “super-Earth” with a permanent dayside hot enough to melt metal—and discovered it’s a dark, barren rock with no atmosphere. Tue, 05 May 2026 20:57:44 EDT https://www.sciencedaily.com/releases/2026/05/260504154012.htm https://www.sciencedaily.com/releases/2026/05/260502233926.htm Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way. By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new worlds, and identified thousands more promising candidates. What makes this especially exciting is the discovery of rare and extreme planets, like those that whip around their stars in less than a day and others lurking in the mysterious “Neptunian desert,” where planets are thought to be scarce. Sun, 03 May 2026 00:56:52 EDT https://www.sciencedaily.com/releases/2026/05/260502233926.htm https://www.sciencedaily.com/releases/2026/04/260428045553.htm Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a telltale U-shaped pattern showing that star formation drops sharply around 35,000–40,000 light-years from the center. Beyond that, stars are mostly migrants, slowly drifting outward rather than forming in place. The discovery gives a long-sought answer to where our galaxy’s stellar nursery really ends. Wed, 29 Apr 2026 02:33:19 EDT https://www.sciencedaily.com/releases/2026/04/260428045553.htm https://www.sciencedaily.com/releases/2026/04/260423031532.htm A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium. But just days later, the signal shifted, behaving more like a supernova, leaving researchers puzzled. Now, some think they may have witnessed something never seen before: a “superkilonova.” Fri, 24 Apr 2026 10:02:52 EDT https://www.sciencedaily.com/releases/2026/04/260423031532.htm https://www.sciencedaily.com/releases/2026/04/260423031528.htm Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly. Thu, 23 Apr 2026 03:15:28 EDT https://www.sciencedaily.com/releases/2026/04/260423031528.htm https://www.sciencedaily.com/releases/2026/04/260422044618.htm Scientists have discovered unexpected water-ice clouds on a distant, Jupiter-like exoplanet, challenging current atmospheric models. By directly imaging Epsilon Indi Ab with the James Webb Space Telescope, they found less ammonia than expected—likely hidden by thick, patchy clouds. The finding reveals new layers of complexity in giant planets and shows how much we still have to learn. Wed, 22 Apr 2026 05:24:39 EDT https://www.sciencedaily.com/releases/2026/04/260422044618.htm https://www.sciencedaily.com/releases/2026/04/260421042812.htm Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways. Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid phase—part solid, part fluid—where hydrogen atoms spiral through a rigid carbon framework. This unusual “superionic” structure could reshape how heat and electricity flow inside these distant worlds, potentially helping explain their mysterious magnetic fields. Tue, 21 Apr 2026 09:24:21 EDT https://www.sciencedaily.com/releases/2026/04/260421042812.htm https://www.sciencedaily.com/releases/2026/04/260417224507.htm Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit is none other than Einstein’s theory of general relativity. Sun, 19 Apr 2026 06:17:19 EDT https://www.sciencedaily.com/releases/2026/04/260417224507.htm https://www.sciencedaily.com/releases/2026/04/260415043607.htm A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time. If life spreads and changes planetary environments, it could leave behind statistical clues linking planets together. These patterns may reveal life even when traditional biosignatures are unclear or misleading. The method could help scientists prioritize which planets are most likely to host life. Wed, 15 Apr 2026 08:17:34 EDT https://www.sciencedaily.com/releases/2026/04/260415043607.htm https://www.sciencedaily.com/releases/2026/04/260406192917.htm Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, phosphorus and nitrogen, to stay where life could use them. Too much or too little oxygen, and those ingredients could be lost or trapped deep inside the planet. This could reshape the search for life by showing that water alone is not enough. Mon, 06 Apr 2026 23:36:59 EDT https://www.sciencedaily.com/releases/2026/04/260406192917.htm https://www.sciencedaily.com/releases/2026/04/260406192905.htm A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere surprisingly poor in heavy elements—even less enriched than its own star, which defies current theories of how giant planets form. Mon, 06 Apr 2026 23:28:14 EDT https://www.sciencedaily.com/releases/2026/04/260406192905.htm https://www.sciencedaily.com/releases/2026/04/260403224454.htm Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many have already been swallowed. The likely cause is a gravitational tug that drags planets inward until they break apart or fall into the star. It’s a dramatic glimpse into the chaotic final stages of planetary systems. Sat, 04 Apr 2026 04:21:18 EDT https://www.sciencedaily.com/releases/2026/04/260403224454.htm https://www.sciencedaily.com/releases/2026/04/260403224450.htm A group of undergraduate students stumbled into a cosmic time capsule—one of the oldest stars ever discovered—while combing through massive astronomy datasets. What began as a class project quickly turned into a breakthrough when they spotted an extraordinarily “pristine” star made almost entirely of hydrogen and helium, hinting it formed near the dawn of the universe. Sat, 04 Apr 2026 04:07:31 EDT https://www.sciencedaily.com/releases/2026/04/260403224450.htm https://www.sciencedaily.com/releases/2026/04/260403002014.htm Saturn’s magnetic field isn’t the smooth, symmetrical shield scientists see around Earth. Instead, it’s noticeably skewed, and researchers now think they understand why. By analyzing years of data from the Cassini spacecraft, scientists found that a key region where solar particles enter Saturn’s atmosphere is consistently shifted to one side. This distortion appears to be driven by the planet’s rapid spin combined with a thick cloud of charged particles coming from its moon Enceladus. Fri, 03 Apr 2026 20:44:51 EDT https://www.sciencedaily.com/releases/2026/04/260403002014.htm https://www.sciencedaily.com/releases/2026/03/260326075618.htm Scientists have uncovered a surprising way to study the harsh space weather around young M dwarf stars. Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ magnetic fields. These structures act like built-in space weather monitors, revealing how energetic particles affect nearby planets. The findings could reshape how we think about whether planets around these common stars can survive—or even host life. Fri, 27 Mar 2026 04:53:17 EDT https://www.sciencedaily.com/releases/2026/03/260326075618.htm https://www.sciencedaily.com/releases/2026/03/260325041723.htm A star you can see with the naked eye has kept astronomers guessing for decades with its unusually powerful X-rays. Now, thanks to highly precise observations from Japan’s XRISM space telescope, scientists have finally uncovered the source: a hidden white dwarf companion pulling in material and generating extreme heat. This discovery not only solves a 50-year-old mystery surrounding Gamma Cassiopeiae, but also confirms the existence of a long-predicted type of binary star system. Wed, 25 Mar 2026 04:51:37 EDT https://www.sciencedaily.com/releases/2026/03/260325041723.htm https://www.sciencedaily.com/releases/2026/03/260325005926.htm Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known exoplanets that may have the right conditions to support life. Using new data from ESA’s Gaia mission and NASA archives, researchers pinpointed worlds in the “habitable zone,” where temperatures could allow liquid water to exist. Some of the most intriguing targets include nearby systems like TRAPPIST-1 and Proxima Centauri, offering tantalizing possibilities just dozens of light-years away. Wed, 25 Mar 2026 03:56:19 EDT https://www.sciencedaily.com/releases/2026/03/260325005926.htm https://www.sciencedaily.com/releases/2026/03/260324024300.htm Astronomers have finally cracked a decades-old mystery about red giant stars—how material from their deep interiors makes its way to the surface. Using cutting-edge supercomputer simulations, researchers discovered that stellar rotation plays a powerful role in mixing elements across a previously unexplained barrier inside the star. Tue, 24 Mar 2026 07:52:48 EDT https://www.sciencedaily.com/releases/2026/03/260324024300.htm https://www.sciencedaily.com/releases/2026/03/260322020255.htm Astronomers have uncovered surprising evidence of a thick atmosphere surrounding TOI-561 b, a scorching, fast-orbiting rocky planet once thought too extreme to hold onto any gas. Using NASA’s James Webb Space Telescope, researchers found the planet is far cooler than expected for a bare rock, hinting at a heat-distributing atmosphere above a churning magma ocean. This strange world—where a year lasts just over 10 hours and one side is locked in eternal daylight—may even be rich in volatile materials, behaving like a “wet lava ball.” Sun, 22 Mar 2026 04:19:46 EDT https://www.sciencedaily.com/releases/2026/03/260322020255.htm https://www.sciencedaily.com/releases/2026/03/260317190802.htm Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of sulfur deep inside. Observations from the James Webb Space Telescope revealed unusual sulfur-rich gases in its atmosphere and a surprisingly low density for its size. Tue, 17 Mar 2026 19:13:24 EDT https://www.sciencedaily.com/releases/2026/03/260317190802.htm https://www.sciencedaily.com/releases/2026/03/260317064449.htm Kepler-51d is a giant, ultra-light “super-puff” planet wrapped in an unusually thick haze that’s blocking scientists from seeing what it’s made of. Observations from JWST revealed that this haze may be one of the largest ever detected, possibly stretching as wide as Earth itself. The planet’s low density and close orbit don’t match existing models of how gas giants form or survive. Now, researchers are left with more questions than answers about how such a strange world came to be. Wed, 18 Mar 2026 00:47:28 EDT https://www.sciencedaily.com/releases/2026/03/260317064449.htm https://www.sciencedaily.com/releases/2026/03/260314030452.htm Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA’s twin-spacecraft ESCAPADE mission aims to watch this process in action by measuring how the solar wind interacts with Mars’ fragile magnetic environment. The findings could reveal how Mars lost its habitability—and help prepare humans for future missions there.

A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they realized the strange dimming was caused by vast clouds of hot dust and debris drifting across the star. The most likely explanation is a violent planetary collision—two worlds smashing together and scattering glowing material throughout the system. Wed, 11 Mar 2026 23:08:41 EDT https://www.sciencedaily.com/releases/2026/03/260311213429.htm https://www.sciencedaily.com/releases/2026/02/260222085206.htm Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes could form without violent collisions tearing them apart. Now researchers at Michigan State University have recreated the process in a powerful new simulation, showing that simple gravitational collapse can naturally produce these cosmic “snowmen.” Mon, 23 Feb 2026 02:47:10 EST https://www.sciencedaily.com/releases/2026/02/260222085206.htm https://www.sciencedaily.com/releases/2026/02/260213223857.htm Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky planets close in and gas giants farther out — the same pattern seen in our own Solar System and hundreds of others. And at first, that’s exactly what they saw. But new observations revealed a surprise: the outermost planet appears to be rocky, not gaseous. Fri, 13 Feb 2026 22:38:57 EST https://www.sciencedaily.com/releases/2026/02/260213223857.htm https://www.sciencedaily.com/releases/2026/02/260213223855.htm A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a slow-motion cosmic fade-out. The leftover debris continues to glow in infrared light, offering a long-lasting signal of the black hole’s birth. The finding reshapes our understanding of how some of the universe’s biggest stars meet their end. Sat, 14 Feb 2026 00:42:40 EST https://www.sciencedaily.com/releases/2026/02/260213223855.htm https://www.sciencedaily.com/releases/2026/02/260212234205.htm A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, the dying star blasts twin beams of light through a polar opening, carving glowing lobes and delicate ripples into the surrounding cloud. These striking, symmetrical arcs hint that unseen companion stars may be shaping the spectacle from within. Fri, 13 Feb 2026 07:48:37 EST https://www.sciencedaily.com/releases/2026/02/260212234205.htm https://www.sciencedaily.com/releases/2026/02/260212025607.htm A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, this icy world could still surprise us. Thu, 12 Feb 2026 08:32:43 EST https://www.sciencedaily.com/releases/2026/02/260212025607.htm https://www.sciencedaily.com/releases/2026/02/260211073047.htm For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s Swift Observatory toward it, they caught the first-ever hint of water from such an object, detected through a faint ultraviolet glow of hydroxyl gas. Even more surprising, the comet was blasting out water at a rate of about 40 kilograms per second while still far from the Sun—much farther than where most comets “switch on.” Wed, 11 Feb 2026 09:08:24 EST https://www.sciencedaily.com/releases/2026/02/260211073047.htm https://www.sciencedaily.com/releases/2026/02/260211073019.htm A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed like Jupiter, by slowly building solid cores. That’s unexpected because these planets are far bigger and orbit much farther from their star than models once allowed. Wed, 11 Feb 2026 07:30:19 EST https://www.sciencedaily.com/releases/2026/02/260211073019.htm https://www.sciencedaily.com/releases/2026/01/260131084138.htm Jupiter’s swirling storms have concealed its true makeup for centuries, but a new model is finally peeling back the clouds. Researchers found the planet likely holds significantly more oxygen than the Sun, a key clue to how Jupiter—and the rest of the solar system—came together. The study also reveals that gases move through Jupiter’s atmosphere much more slowly than scientists once thought. Together, the findings reshape our understanding of the solar system’s largest planet.

Four massive but extremely low-density worlds orbiting the star appear to be inflated precursors of super-Earths and sub-Neptunes. By watching how the planets subtly tug on one another, scientists measured their masses and confirmed they are far puffier than expected. The system reveals how these planets dramatically shrink and transform as they age.

A new study proposes that dark stars—hypothetical stars powered by dark matter—could tie all these surprises together. These exotic objects may have grown huge very quickly, lighting up the early cosmos and planting the seeds of supermassive black holes.

The radio waves reveal that the star violently shed huge amounts of material shortly before it exploded, likely due to interaction with a nearby companion star. This discovery gives scientists a new tool to rewind the clock on stellar deaths. It also shows that some supernovae are far more dramatic in their final moments than previously thought.

The detailed view highlights glowing knots of gas shaped by fast-moving stellar winds colliding with older material. Changes in color trace a shift from scorching hot gas near the center to cooler regions farther out. The scene captures how stellar death helps supply the building blocks for future worlds.

Observations revealed a gigantic disk of gas and dust filled with vaporized metals, swirling around an unseen companion object. For the first time, scientists directly measured the motion of these metallic winds inside such a disk. The findings suggest that even ancient star systems can still experience catastrophic planetary smashups.

Scientists found that simple amino acids bond into peptides on interstellar dust, long before stars and planets exist. This challenges the idea that complex life chemistry only happens on planets. It also boosts the odds that life-friendly ingredients are widespread across the universe.

The process produced streams of glowing plasma blobs that rained through the Sun’s atmosphere long after the flare itself.

Instead of a single stream of escaping gas, the planet is wrapped in two colossal helium tails—one trailing behind like a comet, the other stretching ahead toward its star.

The structure is enormous, spanning hundreds of times the size of Pluto’s orbit and containing a Mars-sized amount of iron. It was detected using a new instrument that allowed astronomers to map the nebula in far greater detail than ever before. The origin of the iron bar is still a mystery, with one theory suggesting it could be the remains of a vaporized planet.

The dust grains around the star are simply too small to be pushed outward by light alone. This raises new questions about how giant stars spread life-essential elements through space. Researchers now suspect dramatic stellar motions or pulsations may play a key role instead.

Using nearly eight years of observations from NASA’s Hubble Space Telescope and ground-based observatories, scientists detected swirling trails of dense gas created as the companion, called Siwarha, moves through Betelgeuse’s outer layers.

One of these clouds was even mistaken for a planet before slowly fading away. Seeing two such events in just two decades hints that violent impacts may be surprisingly common in young star systems. It’s like watching planets-in-the-making collide before our eyes. Wed, 07 Jan 2026 18:21:49 EST https://www.sciencedaily.com/releases/2026/01/260106224642.htm
