Q0906+6930

From Wikipedia, the free encyclopedia

Q0906+6930 is the most distant known blazar (redshift 5.47 / 12.7 billion light years), discovered in July, 2004. The engine of the blazar is a supermassive black hole approximately 16 billion times the mass of the Sun (roughly 3% the mass of the Milky Way Galaxy). The event horizon volume is on the order of 1000 times that of the Solar System. It is one of the most massive black holes on record.
