With the help of the European Southern Observatory s Very Large Telescope (ESO s VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a radio-loud quasar a bright object with powerful jets emitting at radio wavelengths that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

PHOENIX – A team led by University of Arizona astronomers has discovered the most distant quasar found to date. Researchers hope the quasar, which is more than 13 billion light-years

At the center of the quasar’s galaxy is a black hole that constantly emits matter. J0313-1806 is not only significant for its distance, but it also contains a black hole so heavy that the discovery is making scientists question their hypotheses of how black holes form. “This particular quasar has a black hole of one and a half billion times the mass of the sun, and it is from a time the universe was so young that it barely had time to form these objects,” Fan said. “We’re looking at a big object in a baby universe. So, the question is, how long does it take for these objects to form?”
