If a pair of black holes coalesce into one, much of that vast energy can be released in a few seconds.

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

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

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 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 ...

Astronomers suspect that the flare is a a burst of radiation that occurs when a black hole consumes a hapless star, ripping it apart and swallowing it. Astronomers are continuing to monitor the black ...

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