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

And, scientists with the National Aeronautics and Space Administration (NASA) have detected what they like to call a ...

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.

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 ...

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 ...

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 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.

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.

This would then result in a rogue interstellar black hole just roaming through space. "There also could be a black hole on the edge of the solar system ," Smethurst said.

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.
