When the researchers calculated the black hole's energy output, they were met with an additional surprise. It's about equal to the energy released by a gamma-ray burst (GRB). Since GRB are the ...

Supermassive black holes can be very bright if they are actively eating, usually a brightness that stays there for a very ...

What can dormant black holes teach astronomers about tidal disruption events (TDEs), which is the bright flash observed when a black hole consumes a star that passes too close to it? This is what a ...

A distant black hole tore apart a star and then stayed active for years, emitting powerful energy that continues to grow.

Back in 2024, a system set up to identify objects that suddenly brighten found something unusual. Unfortunately, the automated system that was supposed to identify it couldn’t figure out what it was ...

Black holes are often considered terrors of the known universe. Supermassive black holes are regions of space where the pull of gravity is so intense that even light doesn't have enough energy to ...

Add Yahoo as a preferred source to see more of our stories on Google. These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...

Learn how a shredded star triggered a black hole jet that evolved into a years-long energy surge that continues to intensify.

Tidal disruption events (TDEs) occur when a star ventures too close to a supermassive black hole and is gravitationally torn apart by tidal forces. The resulting stellar debris forms an accretion disc ...
