A bright quasar, powered by a supermassive black hole, emits radiation that pushes clouds of gas away from its surroundings, generating winds at speeds of about 58 million kilometers per hour. Oh, and the quasar is also almost as old as the universe itself. The discovery, made by a team of scientists led by astronomers … Read more
