GNz7q
Galaxy in the constellation Ursa Major
From Wikipedia, the free encyclopedia
GNz7q is a starburst galaxy with a candidate proto-supermassive black hole in the early Universe, at a redshift of 7.1899 ± 0.0005,[2] estimated to have existed only 750 million years after the Big Bang. It was discovered in the Great Observatories Origins Deep Survey-North (GOODS-North) field taken by the Hubble Space Telescope.[3]

The discovery is "the first observation of a rapidly growing black hole in the early universe" and is thought to help explain the growth of supermassive black holes less than a billion years after the Big Bang.[4]
