Discovered Quasar Burns 100 Times Brighter Than Entire Milky Way

Astronomers have found a galaxy whose super-luminous nucleus--called a quasar--is burning 100 times as much energy as the entire Milky Way galaxy.

Though theory has long predicted that quasars this powerful should exist, the newly-discovered object, known as SDSS J1106+1939, is by far the most energetic ever observed. The quasar is powered by a supermassive black hole that lies at its center.

Scientists made the discovery using the X-shooter spectrograph instrument attached to ESO's Very Large Telescope. The spectrograph split light coming from the quasar into its component wavelengths, allowing astronomers to observe the movement of material close to the quasar. The team calculated that the quasar is spewing an annual 400 suns worth of gas and dust, at a velocity of nearly 5000 miles per second. ( via popsci.com )
