On Earth, CI chondrites make up only 1% of all meteorites that have been collected, but they may be far more common on the moon.

This new analysis could be used to test the physics of quantum chromodynamics in the future.

The destroyed planet has spewed material onto the white dwarf's surface, with astronomers detecting 13 different elements originating from the rocky body.

The super-Earth exoplanet is "one of the best candidates in the search for an atmospheric signature of life."

The new technique could one day be used to create less expensive astronomical sensors.

At the end of October Europa Clipper will fly in line with 3I/ATLAS’ ion tail — but will any of the charged particles reach the spacecraft, and will the spacecraft be ready to receive them?

Titan's chemical inventory is believed to bear some resemblance to the prebiotic soup on the early Earth.

V883 Orionis is a young star that formed in the Orion Nebula half a million years ago.

The so-called tidal disruption event also produced two puzzling delayed outbursts.

Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational waves that date back to inflation at the moment of the Big Bang.

Three new ORCS – "odd radio circles" – have been found associated with giant, active galaxies, giving astronomers clues as to how these immense, enigmatic structures form.

The discovery of what is potentially the smallest clump of dark matter ever seen strengthens the case for cold dark matter.

The isotopic ratio of sulfur-33 on the moon differs from that of Earth. Did the moon's sulfur instead come from the impactor that formed it?

As part of World Space Week, which is highlighting the theme of living in space, we look at one scientist's dream of gigantic space habitats.

After marking the 30th anniversary of the discovery of the first exoplanet around a sun-like star, we now look forward to what the next 30 years might offer.

JWST's detection of phosphine on a brown dwarf, also known as a "failed star," could have repercussions for the claimed detection of the molecule on Venus.

The discovery of the "hot Jupiter" exoplanet 51 Pegasi b on Oct. 6, 1995 changed the course of astronomical history.

The discovery strengthens the case for a new mission to orbit and land on Enceladus and search for evidence of life.

What about those previously studied plumes of methane and meteorites potentially stuffed with the fossils of Martian microbes?

The JWST has studied the chemical composition of a moon-forming disk circling a giant planet 625 light-years away.

Scientists are testing prototypes of tumbleweed rovers in a wind tunnel that show that Mars' winds are strong enough to push them.

The algorithm has already been tested on images from the Subaru telescope and will now be used on the Vera C. Rubin Observatory once science results begin to flood in.

The small chunk of rock could be telling us that many of the moon’s largest impacts happened over 4.25 billion years ago.

The star-forming region called Sagittarius B2 contains half of the galactic center's stars, yet only 10% of the gas.

Two galaxies connected by a bridge of hydrogen gas are falling into the Virgo Cluster.
