The cosmological constant, which describes how our universe expands, may not be constant after all.

A Montana fossil reveals that Nanotyrannus, once thought to be a young T. rex, was actually a full-grown predator and it's fierce rival.

Could the lunar surface hold the key to clean energy—and a new geopolitical order?

Buried for centuries, a teenage boy's body was found eerily intact—and entirely green. What scientists uncovered inside his coffin is rewriting what we thought we knew about mummification and the strange power of metal in the grave.

"What we don't want to see is this turned into a bunch of multi-million dollar homes."

The James Webb and Very Large telescopes spotted a free-floating planet accreting material at a record rate, displaying behavior similar to how stars form. Scientists aren't clear as to why.

A place warmer than the inside of a cooked tomato, the NASA discovery could redefine how we view our universe.

A new study reveals that Earth’s climate “thermostat” may sometimes overreact, turning global warming into an unexpected deep freeze.

The newly-discovered species is being called the “death-ball sponge” for its appendages, which end in orbs and are covered in micro-hooks meant to capture pr...

New photos show that the recently discovered comet C/2025 K1 (ATLAS) developed a surprising golden glow after reaching its closest point to the sun. Until now, the comet has gone under the radar, largely thanks to the more famous interstellar comet 3I/ATLAS.

The ability to make art has often been considered a hallmark of our species.

This 180-sided object cannot fit through another like it, no matter where you bore the hole or how you tilt it.

The object, initially thought to be a meteorite, could actually be Zond 1, a Soviet spacecraft that was destined for Venus 60 years ago.

In fact, flying west (against the rotation of the Earth) takes a little longer than flying east.

NASA's Mars rover just uncovered something buried deep in ancient Martian rock—signals so unusual they’re making scientists rethink what they know about life beyond Earth.

How AI fixed the James Webb Space Telescope's blurry vision

Both NASA and Blue Origin have a lot riding on this flight. You won’t want to miss it.

Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes at the center of the galaxy M87 and our Milky Way, published a few years ago by the Event Horizon Telescope (EHT) collaboration, broke…

Unusual radio signals from beneath Antarctica’s ice continue to defy explanation. Several years ago, scientists using a cosmic particle detector in Antarctica recorded a series of puzzling radio signals, according to an international research collaboration th…

The motions of stars in the Milky Way have revealed a giant outward ripple, set off by a massive event sometime in our galaxy's wild past.

A newly discovered marine reptile from the Jurassic period, nicknamed the "Sword Dragon," sheds light on the evolution of ancient seas and the fascinating world of ichthyosaurs.

James Webb Space telescope spots 'big red dot' in the ancient universe: A ravenous supermassive black hole named 'BiRD'

Satellites detect that Iran's Taftan volcano has risen 3.5 inches, which is an indication of internal pressure and volcanic reactivation.

A theoretical framework predicts the emergence of non-reciprocal interactions that effectively violate Newton's third law in solids using light, report researchers from Japan. They demonstrate that by irradiating light of a carefully tuned frequency onto a ma…
