Astronomers have used specialized telescopes, such as the Hubble Space Telescope and the Chandra X-ray Observatory, to identify the oldest and most distant black hole known to exist, formed shortly after the Big Bang. This object, first discovered in 2001, is called the quasar ULAS J1120+0641, and is estimated to be 13 billion light years away and 800 million times more massive than our own Sun. Scientists believe that it formed a mere 690 million years after the Big Bang, and is likely part of one of the earliest generations of quasars in the universe.
