Triple star systems are very common in the universe, but now astronomers have found a system where one of the stars is a black hole. They're located in the V404 Cygni system, about 8,000 light-years away. At the center is a black hole consuming a small star, while a third star is orbiting the black hole every 70,000 years or so. Astronomers had spotted this third star a long time ago, but only recently discovered that it's part of the system thanks to Gaia.
