Astronomers find 'truly black' black hole lurking in a nearby star system Scott Sutherland mercredi, 6 mai 2020 à 17:30 - This discovery of a black hole hiding in a star system so close to us was quite the surprise for astronomers. An international team of astronomers has located the closest known black hole to Earth, hidden in a star system just 1,000 light-years away. The discovery of this nearby black hole was not only a welcome surprise, but it may help astronomers to find more of these lurking out in space. It may come as quite the surprise to stargazers in the southern hemisphere, but a black hole has been hiding in plain view to them, every night.
