Scientists say a jet from a previously studied supermassive black hole has grown brighter, becoming one of the most energetic events in the universe.

A new finding of ammonia on the icy surface of Jupiter's moon Europa could have important implications for the search for extraterrestrial life.

AI helped researchers probe the Hubble Space Telescope's archive to find strange celestial objects, including some indescribable by science.

Mars may have been a "blue planet" with an ocean the size of today's Arctic Ocean, a new study suggests.

A supermassive black hole embedded in an early galaxy likely starved the galaxy of gas needed to form young stars, new observations revealed.

Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this is a newly found type of star-forming galaxy.

JWST peered at the glowing trail of stars left behind by a candidate runaway supermassive black hole deep in space, revealing new insights after other telescopes looked at the event.

In its preliminary data release, taken from just seven nights of observations, the powerful Vera C. Rubin Observatory has discovered an enormous, fast-spinning asteroid that sets a new record.

Scientists using the James Webb telescope observed a distant exoplanet with an atmosphere of soot and diamonds, challenging all explanations.

Decades ago, a spacecraft suggested Saturn's largest moon, Titan, had an ocean. New observations suggest that the liquid may look more like slush.

Tracking comets accurately is hard. A new effort with the U.N. and NASA aims to better chart these visitors using 3I/ATLAS.

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.
