AI Insight
Astronomers have discovered 31 of the oldest known quasars, with the two earliest dating to when the universe was approximately 670 million years old. These extremely luminous objects are powered by supermassive black holes that are billions of times more massive than the Sun. Their existence at such an early cosmic epoch challenges current theoretical models of how supermassive black holes could have formed and grown so rapidly after the Big Bang.
Why it matters
This discovery requires scientists to reconsider existing theories about black hole formation and growth in the early universe. Understanding how these massive objects formed so quickly could reveal new physics about the conditions and processes present in the first billion years after the Big Bang.
Understand the Science
Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects challenge scientists’ understanding of how such enormous black holes formed so quickly after the Big Bang.
