Images from NASA’s DART mission revealed faint streaks on the moon Dimorphos—evidence of slow “cosmic snowballs” drifting from its parent asteroid, Didymos. The discovery provides the first direct visual proof that sunlight can spin asteroids fast enough to shed debris that lands on nearby companions. It also shows that near-Earth asteroids are much more active and constantly reshaped than scientists once believed.

Stretching across 650 light-years, the survey maps the hidden fuel for star formation in remarkable detail and reveals a surprisingly complex chemical brew. This extreme region hosts some of the galaxy’s most massive, short-lived stars. The findings could help explain how stars — and even entire galaxies — formed under the universe’s most chaotic conditions.

An international team of scientists modeled how complex organic molecules—essential building blocks for biology—could have formed in the swirling disk of gas and dust around the young Sun and later been carried into Jupiter’s own moon-forming disk. Their results suggest that up to half of the icy material that built moons like Europa, Ganymede, and Callisto may have delivered freshly made organic compounds without being chemically destroyed.

Located 300 million light-years away in the Perseus galaxy cluster, it was discovered in an unusual way: not by its stars, but by four tightly packed globular clusters acting like cosmic breadcrumbs. Sat, 21 Feb 2026 01:57:52 EST https://www.sciencedaily.com/releases/2026/02/260221000307.htm https://www.sciencedaily.com/releases/2026/02/260217005751.htm Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our galaxy’s core. Pulsars act like incredibly precise cosmic clocks, and finding one in this extreme environment could open a rare window into how space-time behaves under intense gravity.

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/2026/02/260211073047.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/2026/02/260211073026.htm Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove of organic molecules using the James Webb Space Telescope. Peering through the cosmic veil in infrared light, researchers detected an extraordinary mix of carbon-rich compounds — including benzene, methane, and even the highly reactive methyl radical, never before seen outside the Milky Way. Thu, 12 Feb 2026 00:48:01 EST https://www.sciencedaily.com/releases/2026/02/260211073026.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/2026/02/260206012206.htm Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of material far beyond. This dark matter structure would have a compact core that pulls on nearby stars like a black hole, surrounded by a broad halo shaping the galaxy’s outer motion. Sat, 07 Feb 2026 11:26:18 EST https://www.sciencedaily.com/releases/2026/02/260206012206.htm https://www.sciencedaily.com/releases/2026/02/260203020205.htm Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA’s James Webb Space Telescope, the research shows how dark matter gathered ordinary matter into dense regions, setting the stage for galaxies like the Milky Way and eventually planets like Earth. Tue, 03 Feb 2026 03:48:13 EST https://www.sciencedaily.com/releases/2026/02/260203020205.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. Sat, 31 Jan 2026 10:28:57 EST https://www.sciencedaily.com/releases/2026/01/260131084138.htm https://www.sciencedaily.com/releases/2026/01/260131084135.htm A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. 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. Sat, 31 Jan 2026 10:16:06 EST https://www.sciencedaily.com/releases/2026/01/260131084135.htm https://www.sciencedaily.com/releases/2026/01/260128075355.htm JWST has revealed a strange early universe filled with ultra-bright “blue monster” galaxies, mysterious “little red dots,” and black holes that seem far too massive for their 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. Wed, 28 Jan 2026 10:05:20 EST https://www.sciencedaily.com/releases/2026/01/260128075355.htm https://www.sciencedaily.com/releases/2026/01/260127112135.htm A repeating fast radio burst has just given up one of its biggest secrets. Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn’t alone, but part of a binary system. The finding strengthens the case that magnetars interacting with stellar companions can generate repeating cosmic flashes. Tue, 27 Jan 2026 11:21:35 EST https://www.sciencedaily.com/releases/2026/01/260127112135.htm https://www.sciencedaily.com/releases/2026/01/260127112129.htm For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. 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. Wed, 28 Jan 2026 01:24:54 EST https://www.sciencedaily.com/releases/2026/01/260127112129.htm https://www.sciencedaily.com/releases/2026/01/260126075846.htm Webb’s latest image of the Helix Nebula reveals a dramatic close-up of a dying star shedding its outer layers. 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. Mon, 26 Jan 2026 08:32:26 EST https://www.sciencedaily.com/releases/2026/01/260126075846.htm https://www.sciencedaily.com/releases/2026/01/260124003822.htm A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering both star-forming regions and the remains of ancient stellar explosions. Scientists can now better distinguish where stars are being born versus where they’ve met dramatic ends. The discovery opens powerful new ways to study the life cycle of stars and the shape of our galaxy. Sat, 24 Jan 2026 03:56:41 EST https://www.sciencedaily.com/releases/2026/01/260124003822.htm https://www.sciencedaily.com/releases/2026/01/260124003813.htm A distant Sun-like star suddenly went dark for months, stunning astronomers who quickly realized something massive was passing in front of it. 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. Sat, 24 Jan 2026 22:45:03 EST https://www.sciencedaily.com/releases/2026/01/260124003813.htm https://www.sciencedaily.com/releases/2026/01/260121034125.htm New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. 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. Wed, 21 Jan 2026 03:41:14 EST https://www.sciencedaily.com/releases/2026/01/260121034114.htm https://www.sciencedaily.com/releases/2026/01/260120000311.htm Astronomers have captured the most dramatic view yet of a planet losing its atmosphere, watching the ultra-hot gas giant WASP-121b for an entire orbit with the James Webb Space Telescope. 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.

Astronomers observed a relatively weak but restless jet blasting outward from the galaxy’s core, wobbling like a spinning top as it plows through surrounding gas. Using a powerful mix of space- and ground-based telescopes, the team showed that this jet heats, ionizes, and flings gas out of the galaxy at a surprisingly high rate. Mon, 19 Jan 2026 22:45:26 EST https://www.sciencedaily.com/releases/2026/01/260119215510.htm https://www.sciencedaily.com/releases/2026/01/260118064633.htm A huge bar of iron has been discovered lurking inside the iconic Ring Nebula. 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.

New research shows they are young black holes hidden inside dense clouds of gas, glowing as they devour their surroundings. These black holes are smaller than expected but grow rapidly, shedding light on how supermassive black holes appeared so early in cosmic history. The finding reveals a violent and messy phase of the universe’s youth. Fri, 16 Jan 2026 03:13:00 EST https://www.sciencedaily.com/releases/2026/01/260115022801.htm https://www.sciencedaily.com/releases/2026/01/260112001037.htm Scientists observing the red giant star R Doradus have found that starlight isn’t strong enough to drive its stellar winds, overturning a long-standing theory. 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. Mon, 12 Jan 2026 05:41:03 EST https://www.sciencedaily.com/releases/2026/01/260112001037.htm https://www.sciencedaily.com/releases/2026/01/260110211158.htm Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA’s James Webb Space Telescope pierced through thick dust to reveal this violent outflow. The process is so intense it’s robbing the galaxy of star-forming gas at a staggering rate. Sat, 10 Jan 2026 23:02:00 EST https://www.sciencedaily.com/releases/2026/01/260110211158.htm https://www.sciencedaily.com/releases/2026/01/260109235153.htm Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. 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.

By monitoring this effect for 10 months, researchers watched the pattern slowly evolve as gas, Earth, and the pulsar all moved. Those changes create minuscule delays in the signal, but measuring them helps keep pulsars incredibly precise. The findings also aid SETI scientists in spotting signals that truly come from beyond Earth.

The event was first signaled by a gamma-ray burst and later confirmed using the James Webb Space Telescope, which was able to isolate the blast from its faint host galaxy. Surprisingly, the explosion closely resembles supernovae linked to gamma-ray bursts in the modern universe. Sun, 28 Dec 2025 11:27:21 EST https://www.sciencedaily.com/releases/2025/12/251228074453.htm https://www.sciencedaily.com/releases/2025/12/251227082708.htm New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams colliding almost immediately, while another shockingly delayed its eruption for more than 50 days before unleashing a powerful blast. These complex outflows create shock waves that produce intense gamma rays, confirming long-standing theories with direct visual evidence. The findings reveal novae as evolving, multi-stage events rather than single, instant explosions.

Known as NGC 2264, this distant star-forming region sits about 2,700 light-years away and is filled with newborn stars lighting up clouds of gas and dust. The stars form a triangular shape called the Christmas Tree cluster, crowned by the dramatic Cone Nebula and wrapped in the swirling Fox Fur Nebula below. Together, these features create a festive cosmic scene spanning nearly 80 light-years, showing how young stars shape their surroundings on a truly galactic scale.

The star, which quietly orbits a dormant black hole, appears to be spinning far faster than it should—and its internal “starquakes” suggest it may have once collided and merged with another star. Even more puzzling, its chemical makeup makes it look ancient, while its internal structure reveals it’s relatively young.

These bright arcs and faint clouds reveal where tiny planet-building bodies collide, break apart, and reshape their systems. Some disks contain sharp edges or unusual patterns that hint at massive planets still waiting to be seen, while others resemble early versions of our own asteroid belt or Kuiper belt. Together, the images form one of the most complete views yet of how newborn solar systems evolve and where undiscovered worlds may be hiding.

With sweeping spiral arms, rapid star formation, and an orderly disk resembling our Milky Way, it defies long-held theories about how slowly galaxies should assemble. Thanks to JWST and gravitational lensing, researchers could examine the galaxy in remarkable detail, revealing that the early Universe was far more capable and dynamic than expected.

Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and change their orbital behavior. This leads the stars to interact much sooner than expected, potentially triggering dramatic cosmic events. The new model may offer clues about the origins of type Ia supernovae.
