'Black Hole Police' Spot Extragalactic Black Hole (ESOcast 255 Light)

The black hole police, a team of astronomers known for debunking black hole discoveries, reported finding a "needle in a haystack". After searching nearly 1000 stars outside our galaxy, they found that one of them has a stellar-mass black hole as a companion. This short video summarises the discovery.
