7 supermassive black hole quasars from 'Cosmic Dawn' discovered
Astronomers have discovered seven supermassive black hole-powered quasars surrounded by dust from the "Cosmic Dawn", when the universe was less than a billion years old. Using Subaru Telescope and James Webb Space Telescope, this marks the first discovery of such hidden yet bright quasars in the early universe. The finding suggests that dust-shrouded quasars are as common as visible ones.
