A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that exploded millions of years ago.

Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, ...

The light from the explosion did not reach Earth till June 29, 2025, when the All-Sky Automated Survey for Supernovae detected it.

Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova -- a red supergiant star cloaked in thick, dust-rich shrouds that ...

This artist's impression shows, about 22 million light-years away, the supernova SN 2024ggi exploding in the galaxy NGC 3621. (ESO/L. Calçada via SWNS) By Dean Murray Scientists have revealed for the ...

WASHINGTON (Reuters) -The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks as it unfolds has remained mysterious. Scientists ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

Astronomers report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.

DS1, collapsed into a black hole without exploding, revealing how stars die in silent “failed supernova” events.
