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 ...

A stellar black hole is one that’s created from the gravitational collapse of particularly massive stars, typically greater than eight solar masses. For context, one solar mass is about equivalent to ...

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 that theorized that when a star underwent direct collapse, it would leave ...

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.

Indian astronomer Kishalay De led study revealed one of the clearest cases of a massive star collapsing directly into a black hole without a supernova, based on NASA NEOWISE data.

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

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

A star in the Andromeda galaxy ran out of nuclear fuel and collapsed into a black hole, without first violently exploding in a supernova. For the first time scientists have studied this process in ...
