The Huge Large Quasar Group is a celestial structure composed of 73 Quasars, that’s about 4 billion light-years in diameter. At the time of its discovery, it was identified as the largest and most massive object in the observable universe, until The Hercules-Corona Borealis Great Wall dethroned it. It was discovered by a team of colleagues led by Roger G. Clowes from the University of Central Lancashire in Preston, UK, reported on January 11, 2013.
