Astronomers using the James Webb Space Telescope have found that Ariel, a moon of Uranus, has some of the most carbon dioxide-rich deposits in the solar system, hinting at a buried water ocean.

Citizen scientists have discovered what may be a brown dwarf racing through the cosmos at around 1.2 million miles per hour. Now astronomers want to know what launched it.

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old?

A "guest star," briefly seen in 1181, was created by colliding dead stars, according to new simulations that may finally solve an 800-year-old cosmic mystery.

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.

Astronomers using the James Webb Space Telescope (JWST) have spotted a previously unseen structure in the atmosphere above Jupiter's famous Great Red Spot.

Using the James Webb Space Telescope, astronomers have discovered an improbably huge black hole near the dawn of time, which doesn't seem to be eating near as much as it should.

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events.

The Gaia space telescope has spotted the dim companions of eight bright stars, suggesting we can expect new glimpses of distant planets.

A low-mass star has been discovered racing through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

Fast radio bursts erupt in the sky around 10,000 times a day, but scientists still struggle to explain them. New research could put astronomers one step closer to a solution.

Two million years ago, an encounter with a cold cloud of gas and dust could have caused our planet's "protective giant bubble" to draw back, potentially cooling our planet, new research claims.

Stephen Hawking suggested nothing lasts forever, including black holes. Scientists may have a way to prove it at last.

New research shows that a planet spotted around the real-life star 40 Eridani A, famous for hosting Dr. Spock's fictional home world in 'Star Trek', may have been an optical illusion all along.

The exoplanet Gliese 12 b is tantalizingly close and moderately warm, situated just 40 light-years away around a red dwarf star. The potentially habitable planet could be a good place to search for alien life, scientists say.

Researchers using NASA's Chandra X-ray telescope have found that a group of "Death Star black holes are swiveling around and pointing at new targets, like the fictional space station in Star Wars."

Scientists have calculated the speed of a spinning supermassive black hole by studying the 'spaghettified' remains of a star it destroyed.

Huge "tiger stripe" fault lines seen on Saturn's moon Enceladus raise hopes that a "long-lived" ocean containing potential alien life may lurk beneath the moon's icy shell.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.

JWST's surprise discovery of methane emissions and likely aurorae over a distant brown dwarf could indicate this "failed star" is orbited by an active moon.

"For the first time, we have physical evidence showing us what was happening in the moon's interior during this critical stage of its evolution, and that's really exciting."

Two projects using the James Webb Space Telescope will look at the auroras of Uranus and Saturn to discover what processes make them tick.
