There's evidence out there for the supernova model of black hole formation. This is when a dying star erupts in a colossal ...

A third, tenuously held companion to the known binary V404 Cygni may signal that at least some black holes form "gently." ...

Astronomers have stumbled upon something truly remarkable: a black hole that's not just part of a binary system, but part of ...

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 ...

"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." ...

The black hole, V404 Cygni, was already known to be circled by a nearby star every 6.5 days. It is likely stripping this stellar companion of matter. (Image credit: NASA's Scientific Visualization ...

which only occurs in the final stages of a star's life. "We've never been able to do this before for an old black hole," Burdge said. "Now we know V404 Cygni is part of a triple, it could have ...

Researchers have discovered something groundbreaking in the world of astrophysics—an incredible system where not one, but a ...

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.
