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 ...

"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 ...

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.

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 ...

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.

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.

But astronomers said finding this new system – comprising a black hole named V404 Cygni and two stars – is “super exciting” ...
