Scientists at Kitt Peak National Observatory near Tucson say they have spotted a “super-cluster” of galaxies that is believed to be the largest known entity in space. The cluster of galaxies is 1 billion light-years long, said Jack O. Burns, a University of New Mexico astronomer. A light-year is almost 6 trillion miles. Scientists believe that formation of such a cluster would require more gravitational force than has previously been attributed to all the galaxies and stars known to humans, Burns said. The largest cluster previously found was about 700 million light-years long and was reported in 1982.
