Astronomers from NASA and the European Space Agency have discovered a once-in-a-rare ring in the universe. The black hole is located in the heart of a near-Earth constellation 6,<> light-years away.
Scientists believe the discovery will help expand our knowledge about the origins of black holes and the evolution of galaxies. Black holes form after the collapse of huge stars and have such a huge gravity that they attract anything that comes close to them, even light.
