The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years away.

Quantum gravity seeks to unify the theory of general relativity with quantum physics to describe how gravity works at very small scales. But there's a big puzzle surrounding the idea.

The molecules are building blocks of the chemical precursors of things such as RNA.

The interstellar comet 3I/ATLAS will make its closest pass to the sun on Oct. 30, and various spacecraft will be watching, seeking clues about the icy wanderer's chemistry and composition.

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.

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 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.
