There was a bang. A big one. It was the beginning of everything, but for several hundred million years, all was darkness. Then, lights started flickering to life, stars and gases and galaxies all coming online.
One of the brightest lights during that dawn had a dark and hungry hole at its heart. More massive than 800 million suns, the black hole existed just 690 million years after the Big Bang, when the universe was still an infant.
Researchers, including Eduardo Bañados, reported the existence of the black hole and it’s accompanying bright quasar in a paper in Nature this week. The astronomers were looking for evidence of black holes in these early days of the universe, but they were still surprised at the sheer size of this one, named J1342+0928.
