NASA's Hubble Helps Astronomers Uncover the Brightest Quasar in the Early Universe

Summary
Zoom Lens in Space Gives Hubble a Peek into the Era of Galaxy Birth
Less than a billion years after the big bang, a monster black hole began devouring anything within its gravitational grasp. This triggered a firestorm of star formation around the black hole. A galaxy was being born. A blowtorch of energy, equivalent to the light from 600 trillion Suns, blazed across the universe. Now, 12.8 billion years later, the Hubble Space Telescope captured the beacon from this event. But Hubble astronomers needed help to spot it. The gravitational warping of space by a comparatively nearby intervening galaxy greatly amplified and distorted the quasar's light, making it the brightest such object seen in the early universe. It offers a rare opportunity to study a zoomed-in image of how supermassive black holes accompanied star formation in the very early universe and influenced the assembly of galaxies.

Astronomers have discovered the brightest object ever seen at a time when the universe was less than one billion years old, with the help of NASA's Hubble Space Telescope. The brilliant beacon is a quasar, the core of a galaxy with a black hole ravenously eating material surrounding it. Though the quasar is very far away — 12.8 billion light-years — astronomers can detect it because a galaxy closer to Earth acts as a lens and makes the quasar look extra bright. The gravitational field of the closer galaxy warps space itself, bending and amplifying the distant quasar’s light. This effect is called ...Visit NASA Science to view the full news release including article text and associated Hubble imagery, graphics, scientific visualizations, videos, captions, text descriptions, and other information.
