Astronomers have discovered the most distant quasar known, which is so far from us that its light has taken more than 13 billion years to reach us. We see this quasar as it was a mere 690 million years after the Big Bang, and its light carries valuable information about the early history of the universe, in particular the reionization phase. At the center of the quasar is a massive black hole with a mass of almost 1 billion solar masses. In addition, the quasar's host galaxy has been found to contain a large amount of gas and dust, challenging models of galactic evolution.
Astronomers have discovered the most distant known black hole: a so-called quasar whose light has taken 13 billion years to reach us. In consequence, the light shows that quasar as it was 13 billion years ago, a mere 690 million years after the Big Bang.

The discovery was part of a concerted, multi-year search for ever more distant quasars led by Fabian Walter and Bram Venemans of the Max Planck Institute for Astronomy. It was made by Eduardo BaƱados, of the Carnegie Institution for Science, using the institution's 6.5 meter Magellan telescopes in Chile, ...
