Astronomers discover 83 supermassive black holes in the early universe

Subaru Telescope spots 13-billion-year-old quasars powered by black holes Princeton University Astronomers from Japan, Taiwan and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the universe was less than 10 percent of its present age. “It is remarkable that such massive dense objects were…
