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 ...

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

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 ...

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.

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.
