The star used to be one of the brightest star in the neighboring Andromeda galaxy.

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

In the nearby Andromeda Galaxy, a massive star bright enough to stand out for years has gone dark. Not in a blaze of glory.

Their research was guided by a prediction from the 1970s: if a star collapses directly into a black hole, it should briefly ...

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 ...

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

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

Astronomers have witnessed a rare cosmic event: a massive star that didn’t explode in a spectacular supernova, but instead ...

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.

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

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to ...

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 ...
