CEERS 1019 is a black hole is in the galaxy previously identified as EGSY8p7 or z910_6811 and may be the oldest known black hole as of 2023. The galaxy and its black hole came into existence about 570 million years after the Big Bang, and the black hole in the center of CEERS 1019 seems to be less massive than any other black holes identified in the early universe.[2][3][4] The authors of a 2023 preprint describing it state that "We find that it is difficult to explain a SMBH of this mass ... with a stellar seed",[5] i.e. gravitational collapse into a stellar black hole. Its mass is 106.95±0.37 solar masses.[1]
