supermassive



Quasars are luminous objects with supermassive black holes at their centres, visible over vast cosmic distances. Infalling matter increases the black hole mass and is also responsible for a quasar’s brightness. Now, using the W.M. Keck observatory in Hawaii, astronomers led by Christina Eilers have discovered extremely young quasars with […]

Discovery in the early universe poses black hole growth puzzle




Using data from NASA’s Great Observatories, astronomers have found the best evidence yet for cosmic seeds in the early universe that should grow into supermassive black holes. Researchers combined data from NASA’s Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope to identify these possible black hole seeds. They […]

NASA telescopes find clues for how giant black holes formed ...



NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that  fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspected, but difficult to prove until now. This discovery has given astronomers their first opportunity to […]
