This is the catalogue designation for a newly discovered quasar that is the most powerful yet seen from the time of the early universe. Data from the Hubble Space Telescope indicates that the quasar could be producing 10,000 stars per year. This compares with just one or so a year in our galaxy.
The statistics for this object are staggering. The quasar has the luminosity of 600 trillion suns, and its super-massive black hole powering the quasar is several hundred million times as massive as the Sun.
Hubble was able to detect the object through the gravitational lensing caused by a dim galaxy positioned between the quasar and Earth. The effect made the quasar look three times bigger and fifty times brighter than it is.
The discovery could provide astrophysicists with new information about the formation of galaxies in the early universe.
