Astronomer Tomotsugu Goto from the Japan Aerospace Exploration Agency(JAXA) has used the Subaru telescope to identify a distant quasar powered by a massive black hole. The quasar is almost 12.7 billion light-years away from Earth in the direction of the constellation Cancer the Crab. It is the most distant one ever found by a Japanese researcher and the eleventh most distant quasar currently known.
