Researchers using the James Webb Space Telescope (JWST) have discovered the most distant active supermassive black hole known to date. The black hole is located within the galaxy CEERS 1019 and existed about 570 million years after the big bang. What makes this black hole unique is its relatively small size, weighing around 9 million solar masses. In addition to CEERS 1019, the researchers identified two other smaller black holes that existed 1 billion and 1.1 billion years after the big bang. JWST also detected eleven galaxies that existed when the universe was 470-675 million years old. These groundbreaking findings have the potential to change our understanding of early black hole formation and galaxy evolution.
