Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe。 A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait usually seen only in much older, evolved galaxies。 This challenges current theories that young galaxies

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

Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber。 Using tiny semiconductor quantum dots that emit single particles of light on demand, the team achieved one of the highest secure key rates yet for t

A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater。 The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel。 Even more impressive, it could replace costly titanium parts used

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 labora

The Rivian Assistant is available for both Gen1 and Gen2 hardware

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 creat

Distinct form of tooth protein in Homo erectus shows up in Denisovans—and us

The type of bar matters when it comes to how it bends and recoils, but why is still a mystery

NASA’s Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed “Atacama” — the entire chunk ripped loose from the ground and stayed stuck to the rover’s drill。 Engineers watched as Curiosity shook, vibrated, tilted, and spun the drill over several days in an effort to free the rock, while cameras captured the

Early galaxy has elements produced by the Universe's first supernovae

"Very painful": Altman relives his Muskian reaction to losing control over OpenAI

A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions。 By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challeng

Scientists may have found a powerful new way to hunt for alien life — not by searching for specific molecules, but by looking for hidden patterns in how those molecules are organized。 Researchers discovered that living systems leave behind a kind of chemical “fingerprint” in the statistical distribution of amino acids and fatty acids, one that cons

Cumberland, B。 is reimagining its coal mining past as a clean energy opportunity。 Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions

A new study suggests AI chatbots may do more than spread misinformation — they can actively strengthen a user’s false beliefs。 Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy theories, or delusions feel more believable and emotionally real。 Researchers warn that AI companions may be

Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space。 The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going。 Despite the shutdown, it continues to send back unique data from beyond our solar system
