In one paper, Einstein and Nathan Rosen showed that general relativity predicted that black holes (which were not yet known by that name) could form in pairs connected by shortcuts through space ...

Black holes are messy eaters—not unlike a five-year-old with a bowl of spaghetti. A star starts out as a compact body but gets spaghettified: stretched to a long, thin strand by the extreme tides of ...

Traditionally thought to go silent after a brief flare of activity, some black holes are now being observed emitting new ...

Even more surprisingly, both the disk and black hole were rotating at a 90-degree angle relative to the rest of the galaxy, meaning both features are essentially "lying on their sides," NASA said.

While black holes are often described as sucking everything, including time, into a point of nothingness, in the paper, white holes are theorised to act in reverse, ejecting matter, energy and ...

Supermassive black holes usually lurk unseen, but when an unlucky star drifts too close they ignite titanic outbursts ...

This illustration depicts a star being torn apart by a supermassive black hole during a tidal disruption event. ESO/M. Kornmesser "It's very much a new phenomenon that we're getting to grips with.

A massive Wolf-Rayet star in the Cygnus X-3 system is speeding toward its destruction, torn apart by the powerful gravitational forces of what may be a black hole. This system, located 32,000 ...

New research has looked at an alternative idea for what black holes are, suggesting that they might not be what we thought. Black holes are an enormous source of gravity, "bubbles", and headaches.

This suggests that NGC 5084 is host to a supermassive black hole tipped on its side, and scientists think it could be evidence of a galactic collision in NGC 5084’s recent past. Sometimes being ...

Scientists have got a peek at what is happening inside of black holes. A new model – built on gravitational waves that were first detected almost 10 years ago – indicates what is going inside ...
