Astronomers have identified J0313-1806 as the most distant quasar yet discovered, observed just 670 million years after the Big Bang. The quasar is powered by a supermassive black hole exceeding 1.6 billion solar masses, an age and size that challenges current cosmological models explaining how such massive objects formed so early in the universe.
