Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest observational record yet of a massive star fading ...

Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

Astronomers watching the Andromeda Galaxy have now seen something they had only theorized before: a massive star that simply vanished, apparently collapsing straight into a black hole instead of ...

An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered ...

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like ...

While that light and dust creates an artistic shape, the image is also giving researchers clues to what’s happening to the pre-planetary nebula. The shape of the dust, NASA explains, hints at gravity ...

It is easy to observe when stars explode in a supernova and become a black hole. It is different when they simply collapse.

Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but ...

NASA’s NEOWISE archival data tracks a massive star in Andromeda fading quietly into a black hole, providing detailed observations of stellar collapse and gas expulsion from 2005 to 2023.
