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

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 ...

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.

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 ...

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 ...

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.

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

The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study.

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 ...

The paper argues that if one supermassive black hole was smaller than the other, their one-sided wrestling mach may have spun weaker gravitational waves out in one direction than the other.

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.

Black holes—areas of space where gravity is so strong that not even light can escape—have long been objects of fascination, with astrophysicists, theoretical physicists and others dedicating ...
