What is a puzzle is the scale of the black hole driving this quasar. It has a mass two billion times that of the Sun.
Its detection is one of a number lately that have indicated the presence many super-massive objects in the early cosmos. Scientists are struggling to explain how these objects could have evolved so big, so fast.
"It is safe to say that the existence of this quasar will be giving some theorists sleepless nights," observed Chris Willott from the Canadian Astronomy Data Centre in a News and Views article in Nature."
