New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Black holes are mysterious objects, and one theory posits that our universe exists inside of one. It sounds strange, but ...

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

A massive star roughly 2.5 million light-years away in the Andromeda Galaxy has quietly disappeared, and the best explanation is that it collapsed directly into a black hole without producing a ...

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 ...
