Despite being “black” and a “hole”, a black hole is not a dark, empty space. In his theory of relativity, Einstein predicted how black holes are formed. When a massive star dies, it leaves a smaller, ...

Black holes are dense and scary. They suck up everything in their way. Their gravity is so strong it bends light and warps ...

The nature of black holes has long been shrouded in mystery, but some astronomers believe the answers are a lot closer to home than expected. A fringe astronomical theory known as "black hole ...

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is ...

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...

What kind of physics is happening inside a black hole? Scientists have a lot of ideas, but taking any concrete measurements is borderline impossible—that is, unless you want to be spaghettified or ...

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 ...
