GNz7q is a starburst galaxy with a candidate proto-supermassive black hole in the early Universe, at a redshift of 7.1899 ± 0.0005, 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. 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.
