Oldest observed black hole in the universe courtesy of the Chandra observatory and Webb telescope.

This is 470 million years after the Big Bang. It has an estimated mass of between 10 and 100 million suns. Its mass is comparable to the mass of its host galaxy in contrast to the black holes in the local universe that are about 0.1% of their host galaxy mass. Such a black hole is believed to form from the collapse of a massive gas cloud.
