Astronomers have discovered the most luminous galaxy ever found, shining with the equivalence of three hundred trillion suns from the far side of the visible universe.
This is Scientific American 60 Second Science. I'm Lee Billings. Got a minute?
Almost all of that light is being produced by the galaxy's central supermassive black hole, not by its stars.
The enlightening finding is in the astrophysical journal.
Black holes are black because light itself cannot escape once fallen in. But a feeding black hole is surrounded by a whirling white-hot disc of glowing debris, material heated to millions of degrees as it spirals down to oblivion.
The black hole in this faraway galaxy is on a feeding frenzy. The activity produces enough light to warm up most of the galaxy's dust which gives the whole galaxy an infrared glow that we can detect from more than twelve and a half billion light years away.
Considering we're seeing this giant black hole's activity from a time when the universe is only a tenth of its present age, astronomers are puzzled about how it could have grown so big and bright so fast.
A young hungry black hole usually takes an occasional break from feeding. Its ??????? can get so intense it pushes incoming material further away. Think of the baby burping mid-meal.
But this particular galaxy's black hole seems to have circumvented this limitation. If it's burping, the burps seem to be few and far between. One theory is that it must be spinning very slowly. The slower a black hole spins, the weaker its repulse of burps may be and longer it can gorge uninterrupted.
Study co-author Andrew Blain of the University of Leicester says that a slow spin may be how this black hole sustained its binge. Which he calls the equivalent of (quote) ' Winning a hot dog eating contest lasting hundreds of millions of years. And if there any mustard with those dogs, rest a shirt, it's hot.
