Astronomers have uncovered something surprising while looking 13 billion years into the past using the James Webb Space Telescope (JWST). They’ve spotted supermassive black hole-powered quasars that appear to be hanging out in isolation. This is odd because, according to current theories, black holes need to be surrounded by a lot of material to grow […]
James Webb Space Telescope sees lonely supermassive black hole-powered quasars in the early universe
Using the James Webb Space Telescope, astronomers have peered back 13 billion years to discover surprisingly lonely supermassive black hole-powered quasars. The James Webb Space Telescope’s (JWST) observations are confusing because isolated black holes should struggle to gather enough mass to reach supermassive status, especially just a few hundred million years after the Big Bang. […]
Supermassive black holes are, as you might expect, rather large – millions and sometimes billions of times as massive as the sun. They lurk at the centre of all large galaxies, including our Milky Way, shaping the growth of these cosmic structures. And yet we can say precious little for certain about how they form […]
