The event horizon is a boundary that marks the outer edge of black holes. It is the point at which nothing, not even light, can escape.

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

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

Outerspace Explained—The Deadly Power of Black Holes. Posted: April 17, 2025 | Last updated: May 2, 2025. Uncover the terrifying power of black holes lurking in the vastness of outer space.

For the first time, physicists have observed a “black hole triple” in space.This new system is about 8,000 light years away from Earth and is made up of a central black hole that is in the act ...

Black holes are some of the most inscrutable phenomena in outer space. They don't have surfaces, like a planet or star. Instead, they have a boundary called an " event horizon ," or a point of no ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

“We think most black holes form from violent explosions of stars, but this discovery helps call that into question,” said Dr. Kevin Burdge, who is a Pappalardo Fellow in the MIT Department of Physics ...

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture.

In science fiction, space explorers routinely zip through wormholes in space-time that are connected by two black holes — celestial objects so dense that not even light can escape their clutches ...

The answer is no. To feed and grow, black holes actually need a little luck, and a big, bright disk of matter around them. "Often we think of black holes as sucking matter in, like a vacuum cleaner.

A supermassive black hole in the center of the Milky Way galaxy is ... Sagittarius A* is also unique because it is 26,000 light years away from Earth — which is considered close in outer space.
