Universe's Most Distant Quasar

July 17, 2011
This brilliant and rare beacon is powered by a black hole with a mass two billion times that of the Sun. The quasar, named ULAS J1120+0641, lies at a redshift of 7.1, which corresponds to looking back in time to a Universe that was only 770 million years old--only five percent of its current age. Prior to this discovery, the most distant quasar known has a redshift of 6.4, the equivalent of a Universe that was 870 million years old. Its discovery could help further our understanding of a universe still in its infancy following the Big Bang.
