Depicted in this artist’s rendering is the central black hole, V404 Cygni (black dot), in the process of consuming a nearby star (orange body at left), while a second star (upper white flash) orbits ...

But in a new study, published Wednesday (Oct. 23) in the journal Nature, researchers discovered that one of these known binary systems, which contains the black hole V404 Cygni feasting on a ...

In the constellation of Cygnus, some 7,800 light-years from Earth, lurks a real space oddity. There, a black hole in a system named V404 Cygni repeatedly engages in behavior that has simultaneously ...

Astronomers have discovered a third star in the V404 Cygni system, now a rare triple black hole system 8,000 light-years away. This finding challenges existing black hole formation theories ...

An artist's rendition of the black hole X-ray binary V404 Cygni. This is the first time a black hole triple has been discovered. An artist's rendition of the black hole X-ray binary V404 Cygni.

The black hole named V404 Cygni at the beginning seemed to be the same, with a small star that spiraled around it every 6.5 days. However, after a closer look it became obvious that this black hole is ...

The system, called V404 Cygni, was thought to be a black hole and a companion star, but a second star billions of kilometres away was also found to be gravitationally connected to the duo.

The team now believes that contrary to being born following a violent explosion of a dying star (a supernova), V404 Cygni was formed through a more gentle process some four billion years ago.

"Overall, it's not surprising that black holes should be in triples, but what's surprising is that this system held onto the outer star after forming the black hole." Astronomers have discovered ...

Out of curiosity, Burdge reviewed an image of V404 Cygni -- a black hole about 8,000 light years from Earth that was one of the very first objects ever to be confirmed as a black hole, in 1992.
