New research sheds light on how a pair of unusual black holes may have been able to keep their companion stars alive — and at a distance.

Black holes exert a tremendous influence on their surroundings, meaning that when they spin, they literally drag the very fabric of space and time around with them. That means nothing can sit still ...

A third, tenuously held companion to the known binary V404 Cygni may signal that at least some black holes form "gently." ...

Some stars may transform into black holes without exploding into supernovae. Now, astronomers have finally spotted it as it ...

Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, ...

The gravitational field of a rotating black hole is powerful and strange. It is so powerful that it warps space and time back ...

Researchers have discovered something groundbreaking in the world of astrophysics—an incredible system where not one, but a ...

“Black Holes Colliding” could be a topic for a disaster movie. Albert Einstein predicted their existence back in 1915, when ...

The outward force from its fusion can no longer counteract the star's powerful gravity, and the star collapses in on itself.

The first is the outer boundary known as the event horizon where the gravitational ... a region that becomes infinitely ...

Many black holes detected to date appear to be part of a pair. These binary systems comprise a black hole and a secondary ...
