The brightest known object in the universe, a quasar 500tn times brighter than our sun, was "hiding in plain sight," researchers say. From a report: Australian scientists spotted a quasar powered by the fastest growing black hole ever discovered. Its mass is about 17bn times that of our solar system's sun, and it devours the equivalent of a sun a day. The light from the celestial object travelled for more than 12bn years to reach Earth. Australian National University scientists first spotted it using a 2.3-metre telescope at the university's NSW Siding Spring Observatory in Coonabarabran. They then confirmed the find using the European Southern Observatory's (ESO's) Very Large Telescope, which has a primary mirror of 8 metres. The findings by the ANU researchers, in collaboration with the ESO, the University of Melbourne, and France's Sorbonne Universite have been published in Nature Astronomy.
