The brightest object in the universe—at least, the brightest we’ve seen yet—shines 500 trillion times brighter than the sun, and it eats a sun a day. Objects like these are rare, and despite their ...

Astronomers have used the unique capabilities of NASA's Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic ...

A newly discovered quasar is a real record-breaker. Not only is it the brightest quasar ever seen, but it's also the brightest astronomical object in general ever seen. It's also powered by the ...

Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational ...

The first-ever sighting of starlight from a galaxy hosting one of the most distant quasars known has revealed an astronomical oddity. Quasars — blazingly bright galactic cores — owe their brilliance ...

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a ...
