James Webb Telescope Reveals Supermassive Black Holes of the Early Universe
Peering deep into space and time, two teams using the NASA/ESA/CSA James Webb Space Telescope have studied an exceptionally bright galaxy called GN-z11, which existed when our 13.8-billion-year-old universe was only about 430 million years old. Also studying JWST data, a team of astronomers led by Lukas Furtak and Adi Zitrin of Ben-Gurion University of the Negev were also able to determine the mass of the supermassive black hole. At about 40 million times the mass of the Sun, it is surprisingly massive compared to the galaxy it hosts.
