A team of international experts have found a stellar-mass black hole. They found it in the Large Magellanic Cloud, a neighbour galaxy to our own. The system, which is located in the Tarantula Nebula, is composed of a hot, blue star with 25 times the Sun's mass and a black hole which is at least nine times the mass of the Sun. The discovery was made thanks to six years of observations obtained with the European Southern Observatory's (ESO's) Very Large Telescope (VLT). The find surprised the team who discovered it - led by Amsterdam University's Tomer Shenar as they are more used to debunking black hole discoveries. Despite the team's nickname the 'black hole police', the team actively encourages scrutiny, and hopes that their work published Monday in Nature Astronomy, will enable the discovery of other stellar-mass black holes orbiting massive stars thousands of which are predicted to exist in Milky Way and in the Magellanic Clouds.
