Scientists using observations from NASA’s Neil Gehrels Swift Observatory have discovered, for the first time, the signal from ...

However, a study published Oct. 23 in Nature has found that the black hole binary system V404 Cygni, which contains a black hole and a small star, has an additional friend — a second star that ...

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a ...

Black holes have only been spotted on their own or in a binary until this discovery, with a single star, neutron star or other black hole companion orbiting tightly around them. Now, according to ...

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.

Most of the black holes that scientists have detected appear to be part of a pair called a binary system. These systems are made up of the black hole and a secondary object like a star ...

Here's how the process unfolds. The story begins with two black holes orbiting far from each other in long, lazy circles. They could have been born as a binary pair of stars, or they may have just ...

This so-called "X-ray binary" of the black hole and its victim star were previously known, and the system has been well-studied. However, a deeper investigation performed by a team led by Kevin ...

The new system holds a central black hole in the act of consuming a small star that's spiraling in very close to the black hole, every 6.5 days—a configuration similar to most binary systems.

An X-ray binary system composed of a black hole and a star in the process of being consumed turns out to have a third member circling. Unless some unlikely scenarios occurred, the existence of ...

A surprising discovery about the black hole V404 Cygnus is expanding our understanding of black holes, the objects they can host, and the way they form. Many black holes detected to date appear to ...
