Which quasar is the most distant known?

J0313−1806 is one of the most distant quasars ever found and has been reported at a redshift of about 7.64. That means we see it as it was only around 670 million years after the Big Bang. It hosts a supermassive black hole with a mass of roughly 1.6 billion Suns, already enormous for such an early era. Discoveries like this help astronomers study how black holes grew so quickly in the young universe. Because the universe is expanding, the light from such objects has been stretched dramatically on its way to Earth.
