Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects we can currently study. A team has discovered 63 new quasars from when the universe was only a billion years old, almost doubling the number of ancient quasars previously known.
