Using the James Webb Space Telescope, scientists have charted billions of years of galactic evolution, finding that galaxies near the dawn of time were much more chaotic than they are today.

NASA's OSIRIS-APEX mission, which was one of 19 designated to be canceled by the Trump administration, has been saved from the chopping block in a last-minute decision. There will be a significant change to its structure, however.

A stunning new video, made from Mars Express orbiter data, allows you to soar over a gigantic maze on the Red Planet in incredible detail.

A giant 'wave' is rippling through the Milky Way, pushing thousands of stars across the galaxy, and scientists don't know what triggered it.

The potential 'city killer' asteroid 2024 YR4 has a small chance of hitting the moon in 2032. In a new paper, scientists probe the logistics of destroying it — possibly with nuclear weapons — before it comes too close.

The polarization pattern around M87* — the first black hole to be directly imaged by the Event Horizon Telescope — has changed direction, and scientists aren't sure why.

A near-Earth asteroid lurked undetected for decades until a telescope in Hawaii spotted it earlier this year. It may be Earth's newest quasi-moon.

Black holes get bigger as they merge, the LIGO Collaboration confirmed with a new observation that could finally prove a decades-old Stephen Hawking theory.

Astronomers using the James Webb Space Telescope have discovered a planet-forming disk that almost entirely lacks water, challenging prevailing theories.

Early Earth may not have had the right ingredients for life — until a nearby Mars-size planet crashed into it, two new studies hint.

The near-Earth asteroid Bennu contains stardust that is older than the solar system and clues about its violent history, three new studies of the asteroid's sample materials show.

With help from AI, astronomers have spotted a never-before-seen kind of supernova that seems to have been blowing up just as it was trying to gobble down a black hole.

We know little about how young galaxies and their black holes grew up.

Alpha Centauri may have a "disappearing planet', new James Webb Space Telescope observations hint. If confirmed, it could be the closest alien planet to Earth that orbits in its star's habitable zone.

The very first stars in the universe may have been much smaller than scientists thought — potentially explaining why we can't find evidence of them today.

Astronomers have used a novel technique to find evidence of a secret "buddy" star orbiting Betelgeuse, one of the brightest objects in the night sky — but this sun-size companion may not survive for long.

Astronomers spotted a baby star displaying the very first signs of planet formation in the zone surrounding it, similar to how our own solar system was born.

Canada will soon roll a rover onto the moon, and you can help name the pioneering machine.

A North Korean ICBM flew 4,350 miles high on Oct. 30, media reports stated. It comes amid growing concern by the U.S. and NATO about North Korean military activities.

Troubleshooting the leaking ISS is ongoing, with NASA and Russia now identifying 50 "areas of concern" and four cracks, according to a media report.

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power.

The moon's glow meets a stunning aurora in a new astronaut image taken from space.

Kepler's sun drawings are the oldest sunspot records with known dates.

The cameras aboard the International Space Station may be ready, but it's still not clear where to point them in order to capture the April 8 total solar eclipse.
