![]() “This ultraluminous quasar with its supermassive black hole provides a unique laboratory to the study of the mass assembly and galaxy formation around the most massive black holes in the early universe.” “And what is the relationship between this monster black hole and its surrounding environment, including its host galaxy? “How can a quasar so luminous, and a black hole so massive, form so early in the history of the Universe, at an era soon after the earliest stars and galaxies have just emerged?” Fan said. The discovery of this quasar, named SDSS J0100+2802, marks an important step in understanding how quasars, the most powerful objects in the universe, have evolved from the earliest epoch, only 900 million years after the Big Bang, which is thought to have happened 13.7 billion years ago.īut Xiaohui Fan, Regents’ Professor of Astronomy at the UA’s Steward Observatory, said the discovery also presents a major puzzle to the theory of black hole growth at early Universe. ![]() The international team which discovered it was led by astronomers from Peking University in China and from the University of Arizona (UA), which explained the significance of the find. Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole we have ever seen.Įverything about the black hole is unimaginably vast. It has the mass of 12 billion solar masses, emits the energy of 420 trillion Suns, and is at a distance of 12.8 billion light-years from Earth.īy contrast, our own Milky Way galaxy has a black hole which is only four million solar masses at its centre.
