ALMA also revealed that tiny icy grains around the comet are releasing methanol like miniature comets, giving astronomers an unusually detailed look at an object from another star system. Wed, 09 Sep 2026 04:47:39 EDT https://www.sciencedaily.com/releases/2026/09/260909005217.htm https://www.sciencedaily.com/releases/2026/09/260907201556.htm Astronomers have detected an exceptionally faint hydrogen radio signal from billions of light-years away using South Africa’s MeerKAT telescope. Instead of finding galaxies one at a time, the technique measures their combined hydrogen glow across enormous stretches of space. The successful detection shows that astronomers may soon be able to create much larger 3D maps of the Universe. Tue, 08 Sep 2026 23:06:55 EDT https://www.sciencedaily.com/releases/2026/09/260907201556.htm https://www.sciencedaily.com/releases/2026/09/260902234442.htm Star formation across the universe has fallen dramatically over the past 4.5 billion years, but astronomers have uncovered a surprising twist: the supply of neutral hydrogen, a key ingredient for making stars, has barely declined. Using China’s FAST radio telescope and data from roughly 2.5 million galaxies observed by DESI, researchers found that star formation was about 2.5 times higher 4.5 billion years ago, while neutral hydrogen levels were only about 1.4 times higher. Thu, 03 Sep 2026 03:48:14 EDT https://www.sciencedaily.com/releases/2026/09/260902234442.htm https://www.sciencedaily.com/releases/2026/09/260901070523.htm NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares of its youth. Those events may help explain ancient ice ages as well as how early Earth stayed warm enough for liquid water when the Sun was much dimmer. Wed, 02 Sep 2026 00:25:48 EDT https://www.sciencedaily.com/releases/2026/09/260901070523.htm https://www.sciencedaily.com/releases/2026/09/260901010656.htm Astronomers have identified a surprisingly young population of fading radio galaxies whose supermassive black holes have already switched off their powerful jets. The confirmed remnants range from about 8 to 42 million years old, suggesting many may disappear from view much faster than previously recognized. More distant remnants also seem to fade especially quickly, helping explain why they have been so difficult to detect. Fri, 04 Sep 2026 06:07:20 EDT https://www.sciencedaily.com/releases/2026/09/260901010656.htm https://www.sciencedaily.com/releases/2026/08/260829035225.htm Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving researchers a new tool for studying primordial and microscopic black holes. Sun, 30 Aug 2026 11:05:09 EDT https://www.sciencedaily.com/releases/2026/08/260829035225.htm https://www.sciencedaily.com/releases/2026/08/260828082345.htm Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young star to suggest that Earth-like worlds could have appeared far earlier than previously believed. Mon, 31 Aug 2026 01:00:01 EDT https://www.sciencedaily.com/releases/2026/08/260828082345.htm https://www.sciencedaily.com/releases/2026/08/260827010514.htm Astronomers have captured their clearest image yet of Betelgeuse’s long-suspected companion, potentially ending a search that lasted about 100 years. The surprisingly massive hidden star could help explain Betelgeuse’s changing brightness and may influence its future supernova. Thu, 27 Aug 2026 08:43:27 EDT https://www.sciencedaily.com/releases/2026/08/260827010514.htm https://www.sciencedaily.com/releases/2026/08/260827010457.htm Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for a major portion of the signal, offering a surprising new way to investigate cosmic dawn and dark matter. Thu, 27 Aug 2026 06:26:04 EDT https://www.sciencedaily.com/releases/2026/08/260827010457.htm https://www.sciencedaily.com/releases/2026/08/260823015000.htm A faint ribbon of stars around a distant galaxy has become the first globular cluster stellar stream ever identified beyond the Milky Way. Because the stars trace the galaxy’s gravity, researchers used the stream to estimate how much invisible dark matter surrounds it and how that matter is distributed. The breakthrough offers astronomers a promising new way to investigate one of the universe’s greatest mysteries. Mon, 24 Aug 2026 08:19:34 EDT https://www.sciencedaily.com/releases/2026/08/260823015000.htm https://www.sciencedaily.com/releases/2026/08/260822015141.htm Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even harder to explain how enormous, mature galaxies formed so soon after the Big Bang. It could also suggest that planets around low-mass stars were more common in the early universe than scientists realized. Sat, 22 Aug 2026 08:36:23 EDT https://www.sciencedaily.com/releases/2026/08/260822015141.htm https://www.sciencedaily.com/releases/2026/08/260822015119.htm Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with every return. Researchers now think the key may be stars that were already spinning extremely fast before being captured. That rapid rotation could explain both the fading flares and how the stars ended up in such extraordinarily tight black hole orbits. Sun, 23 Aug 2026 00:08:52 EDT https://www.sciencedaily.com/releases/2026/08/260822015119.htm https://www.sciencedaily.com/releases/2026/08/260815064808.htm Astronomers may finally have a clue to what happens to the mysterious “little red dots” that crowded the early universe. By studying a spiral galaxy nicknamed the “Saguaro,” researchers found a compact, bright red center that closely resembles these distant objects—but with something Webb usually can’t see around them: a full galaxy. When the team simulated what the Saguaro would look like much farther away, its spiral structure essentially vanished, leaving only the bright red core. Mon, 17 Aug 2026 08:56:43 EDT https://www.sciencedaily.com/releases/2026/08/260815064808.htm https://www.sciencedaily.com/releases/2026/08/260814235849.htm Astronomers have witnessed a black hole violently shredding a massive star, creating one of the most energetic stellar explosions ever observed. The event, nicknamed “the Whippet,” briefly released about 400 billion times the Sun’s energy and sent a shock wave racing outward at one-fifth the speed of light. Months later, scientists spotted unexpectedly fast-moving helium, suggesting that some structure may have survived the destruction. Sat, 15 Aug 2026 23:46:46 EDT https://www.sciencedaily.com/releases/2026/08/260814235849.htm https://www.sciencedaily.com/releases/2026/08/260813045541.htm Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal everything from rare stars and glowing nebulae to hundreds of thousands of X-ray sources and supermassive black holes changing over time. Fri, 14 Aug 2026 00:21:15 EDT https://www.sciencedaily.com/releases/2026/08/260813045541.htm https://www.sciencedaily.com/releases/2026/08/260813045538.htm Astronomers using the James Webb Space Telescope have discovered a bizarre object from just a few hundred million years after the Big Bang that looks like an enormous star but shines far too brightly to actually be one. The mysterious red object, dubbed a “black hole star,” may contain a black hole about 100,000 times the mass of the Sun wrapped inside a dense, star-like cocoon of hydrogen roughly the size of our solar system. Thu, 13 Aug 2026 09:03:55 EDT https://www.sciencedaily.com/releases/2026/08/260813045538.htm https://www.sciencedaily.com/releases/2026/08/260812015206.htm James Webb has captured a striking new infrared view of NGC 2392, the Lion Nebula, revealing the dramatic aftermath of a dying Sun-like star. At its center, a scorching white dwarf is blasting radiation into surrounding gas and dust, carving out the nebula’s lion-like face while illuminating a sprawling “mane” of surviving dusty clumps. Wed, 12 Aug 2026 06:15:19 EDT https://www.sciencedaily.com/releases/2026/08/260812015206.htm https://www.sciencedaily.com/releases/2026/08/260811011146.htm Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic “bounce” model suggests the Universe expanded from an earlier contracting phase, allowing ancient black holes to survive the transition as cosmic fossils. These relics could potentially explain dark matter and why surprisingly massive objects appeared so early in cosmic history. Tue, 11 Aug 2026 06:14:58 EDT https://www.sciencedaily.com/releases/2026/08/260811011146.htm https://www.sciencedaily.com/releases/2026/08/260805082457.htm A supermassive black hole has been found lurking about 30,000 light-years from the center of its galaxy—the first dormant black hole detected so far from a galactic core. It revealed itself only after shredding a passing star and producing a brief, brilliant flare. Astronomers think it may be the remnant of a devoured galaxy or a black hole flung outward during a chaotic cosmic encounter. Thu, 06 Aug 2026 08:16:32 EDT https://www.sciencedaily.com/releases/2026/08/260805082457.htm https://www.sciencedaily.com/releases/2026/07/260731034150.htm Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy. Sat, 01 Aug 2026 22:59:35 EDT https://www.sciencedaily.com/releases/2026/07/260731034150.htm https://www.sciencedaily.com/releases/2026/07/260731034127.htm A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star. It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded. The results suggest black holes may continue reshaping their surroundings long after their brightest fireworks end. Fri, 31 Jul 2026 04:18:29 EDT https://www.sciencedaily.com/releases/2026/07/260731034127.htm https://www.sciencedaily.com/releases/2026/07/260729051515.htm Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way. Sat, 01 Aug 2026 09:33:41 EDT https://www.sciencedaily.com/releases/2026/07/260729051515.htm https://www.sciencedaily.com/releases/2026/07/260727214609.htm NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy. The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass. Tue, 28 Jul 2026 01:54:39 EDT https://www.sciencedaily.com/releases/2026/07/260727214609.htm https://www.sciencedaily.com/releases/2026/07/260727012143.htm Young Jupiter’s powerful magnetic field may have created a safe zone where several large moons could survive. Saturn lacked this protection, possibly explaining why Titan stands almost alone among its largest moons. Mon, 27 Jul 2026 06:24:05 EDT https://www.sciencedaily.com/releases/2026/07/260727012143.htm https://www.sciencedaily.com/releases/2026/07/260726015239.htm Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ALMA telescope in Chile, researchers conducted the observatory’s first SETI survey, searching for narrow signals that could indicate advanced technology. No possible alien transmissions were found, but the study revealed that even a handful of telescope observations may quietly include millions of stars. Thu, 30 Jul 2026 01:09:15 EDT https://www.sciencedaily.com/releases/2026/07/260726015239.htm https://www.sciencedaily.com/releases/2026/07/260724061444.htm Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer. Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of sight, making the Universe appear almost empty. Sat, 25 Jul 2026 09:17:03 EDT https://www.sciencedaily.com/releases/2026/07/260724061444.htm https://www.sciencedaily.com/releases/2026/07/260723084052.htm China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars. The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system. Fri, 24 Jul 2026 03:47:42 EDT https://www.sciencedaily.com/releases/2026/07/260723084052.htm https://www.sciencedaily.com/releases/2026/07/260722032111.htm A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust. Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets. Thu, 23 Jul 2026 01:58:04 EDT https://www.sciencedaily.com/releases/2026/07/260722032111.htm https://www.sciencedaily.com/releases/2026/07/260719035942.htm Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision. Mon, 20 Jul 2026 23:36:16 EDT https://www.sciencedaily.com/releases/2026/07/260719035942.htm https://www.sciencedaily.com/releases/2026/07/260718010156.htm Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around stars and how comets, asteroids and meteorites may have carried those ingredients to Earth. Sun, 19 Jul 2026 09:10:21 EDT https://www.sciencedaily.com/releases/2026/07/260718010156.htm https://www.sciencedaily.com/releases/2026/07/260716023601.htm JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, where gas races around at up to 600 kilometers per second. The findings suggest black holes may recycle their own fuel by heating gas with jets and later drawing the cooled material back in. Fri, 17 Jul 2026 23:09:35 EDT https://www.sciencedaily.com/releases/2026/07/260716023601.htm https://www.sciencedaily.com/releases/2026/07/260715083538.htm A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint. Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star. Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists think a massive brown dwarf companion may have helped send the planet on its fatal plunge. Thu, 16 Jul 2026 06:52:02 EDT https://www.sciencedaily.com/releases/2026/07/260715083538.htm https://www.sciencedaily.com/releases/2026/07/260714225528.htm Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm. The findings match long-standing predictions and suggest our corner of the galaxy may contain many more undiscovered white dwarf binaries. Wed, 15 Jul 2026 02:30:25 EDT https://www.sciencedaily.com/releases/2026/07/260714225528.htm https://www.sciencedaily.com/releases/2026/07/260713000757.htm Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO. Mon, 13 Jul 2026 06:41:43 EDT https://www.sciencedaily.com/releases/2026/07/260713000757.htm https://www.sciencedaily.com/releases/2026/07/260711010128.htm Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gravitational lensing. Mon, 13 Jul 2026 22:30:53 EDT https://www.sciencedaily.com/releases/2026/07/260711010128.htm https://www.sciencedaily.com/releases/2026/07/260710003524.htm Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced civilizations could potentially build energy-harvesting swarms around them more easily. These objects would stand out by glowing in infrared light instead of visible light, lacking the dusty signatures of ordinary stars, and possibly flickering in unusual ways. Fri, 10 Jul 2026 02:04:44 EDT https://www.sciencedaily.com/releases/2026/07/260710003524.htm https://www.sciencedaily.com/releases/2026/07/260707025049.htm Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects challenge scientists’ understanding of how such enormous black holes formed so quickly after the Big Bang.

A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new universe inside the dying star. Driven by dark energy, this miniature cosmos would expand and push back against gravity, preventing complete collapse and creating an exotic object known as a gravastar.

They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass and rotation. The results suggest that magnetic fields and formation processes play a major role in determining how fast worlds end up spinning.

Unusual orbits among distant Kuiper Belt objects have fueled the Planet Nine theory, but recent discoveries are challenging the idea by showing more stable motion than expected. If Planet Nine exists, it may be much farther away than originally thought.

Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.

It will look deep into unexplored parts of the Milky Way, helping scientists compare planetary systems across very different galactic environments. The mission will also uncover rare Earth-sized planets, study thousands of exotic alien atmospheres, and provide a treasure trove of data that could reshape our understanding of how planets form.
