If these black holes lie close enough together, they will ultimately collide and form an even more massive black hole. Across the cosmos, many stars can be found in pairs, gracefully circling one ...

Astronomers have found a remarkably powerful jet shooting out from a black hole that formed just 3 billion years after the ...

To detect such high-energy particles, scientists could use observatories already tracking supernovae, massive black hole eruptions, and other cosmic events, Silk said.

Sometimes a black hole is orbited by a neutron star—the dense corpse of a star also formed from a supernova explosion but which contains less mass than a black hole.

Still image from the numerical simulation at around 1.3 seconds after the neutron star merger. The contours in blue and green show the density of the matter around the central remnant black hole.

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA's Chandra X-ray Observatory. This jet exists early enough in the cosmos that it ...

In roughly 4 billion years, our home Milky Way galaxy may collide with the neighboring Andromeda galaxy. We are approaching Andromeda at roughly 250,000 miles per hour, and scientists have ...

A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

A collision between our Milky Way galaxy and the neighboring Andromeda galaxy, long considered inevitable, may be in question, astronomers say.
