Astronomers have stumbled upon a pair of massive black holes in a distant galaxy that are triggering unusual bursts of light.

Astronomers have witnessed a rare cosmic event a billion light-years away: two supermassive black holes orbiting each other ...

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 ...

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 black ...

into a black hole, no mess, no fuss. The astrometry of V404 Cygni, with a Pan-STARRS image of the system, the trajectories of the stars in the field, and a zoom of the inner binary. (Burdge et al., ...

The tidal event theory is still on the table, only it is now attributed not to an exploding star, but to a gas cloud that's bigger than the binary black hole system itself. The theory belongs to a ...

Black holes are some of the most mysterious and awe-inspiring celestial objects in science, and while pairs of black holes or a black hole orbiting another object like a star, known as binary black ...

A "black hole triple" system has been discovered for the first time, scientists announced. Black holes have only been spotted on their own or in a binary until this discovery, with a single star ...

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

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 ...

There, a black hole in a system named V404 Cygni repeatedly engages in behavior that has simultaneously baffled and delighted scientists. Now it's whipped a brand new trick out of its seemingly ...
