Young Black Hole Had Monstrous Growth Spurt







” A black hole that grew to gargantuan size in the Universe’s first billion years is by far the largest yet spotted from such an early date, researchers have announced. The object, discovered by astronomers in 2013, is 12 billion times as massive as the Sun, and six times greater than its largest-known contemporaries. Its existence poses a challenge for theories of the evolution of black holes, stars and galaxies, astronomers say.

  Light from the black hole took 12.9 billion years to reach Earth, so astronomers see the object as it was 900 million years after the Big Bang. That “is actually a very short time” for a black hole to have grown so large, says astronomer Xue-Bing Wu of Peking University in Beijing. He led an international collaboration that describes the discovery in Nature.

  For its age, this black hole “is really much more massive than anything else we have seen so far”, says Christian Veillet, director of the Large Binocular Telescope Observatory in Tucson, Arizona.”
