Black Holes

New research shows that not only can gas gather itself into planet-size objects, but those objects then are flung throughout the galaxy in a game of cosmic 'spitball.'

The new method will also likely unlock the history of black holes in a little more than a decade.

Original observations suggested that this rare event was a supernova, but new analysis proposes it was an even more rare occurrence.

Two particle jets shot out from the heart of an active galaxy at the speed of light, apparently originating in the vicinity of a massive black hole.

Astrophysicists have broken new ground in ways to observe a star swallowed by a black hole, promising to help paint a clearer picture of this cosmic phenomenon.

When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed -- or "spaghettified" -- as the black hole swallows it.
