James Webb Spots Earliest Known Pair of Quasar Black Holes, Deepening the Mystery of Rapid Cosmic Growth
Astronomers using the James Webb Space Telescope have identified what appears to be the earliest known compact pair of black hole-powered quasars, a discovery that pushes the timeline of supermassive black hole formation deeper into the universe’s infancy. The finding raises a major puzzle: how two enormous black holes could have grown so quickly and so close together less than a billion years after the Big Bang.
