This NASA image obtained in February 2011 shows black holes. |
Light from a bright, ancient galaxy with a super-massive black hole at its core, a finding that would help explain aspects of the young Universe. The phenomenon is called a quasar, which are very bright but very distant galaxies with a mighty black hole at their heart.
Measurements show the quasar's black hole has a mass about two billion times that of the Sun, a size hard to reconcile with current theories. Super-massive black holes, according to a common hypothesis, should take billions of years to build up as they gradually suck in matter from their surroundings.
