Researchers using the James Webb Space Telescope spotted huge stars leaking nitrogen in an early galaxy, hinting that such 'monster stars' might have been the source of ancient supermassive black holes.

Scientists hunted dark matter and solar neutrinos with one of the largest experiments yet. While the neutrinos likely appeared, dark matter results couldn't be confirmed.

New James Webb telescope observations of the 'super-puff' planet WASP-107b show that the exoplanet's runaway atmosphere is frantically escaping into space.

A new study says observations from the NASA Fermi space telescope suggest a halo of dark matter around the center of our galaxy, but more information is needed to confirm the result.

Twin Mars spacecraft were due to launch on Blue Origin's New Glenn rocket on Nov. 12, but an active sun prompted NASA to delay its mission until Thursday (Nov. 13).

In a small blow to the search for extraterrestrial life, a nearby star shot out a strong enough coronal mass ejection to strip away the atmosphere of any rocky planets that could have been in the way.

The James Webb Space Telescope may have discovered Population III stars, the universe's first generation of stars. They may tell us more about how galaxies form.

Astronomers spotted a flaring black hole that may be consuming a star at least 30 times more massive than the sun. At its peak, the flare was brighter than 10 trillion stars.

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.

Physicists have analyzed two enormous black hole mergers that happened one month apart and have come up with tantalizing evidence that rare "second-generation" black holes were involved.

Scientists have spotted elusive "magnetic waves" in the sun's atmosphere that may explain why the sun's corona is much hotter than its surface.

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.
