"Astronomers have discovered a cavalcade of monster galaxysuperclusters, incredibly massive collections of galaxies and galaxy clusters in the universe.
The most striking example of these 662 new superclusters is located around 3 billion light-years away from Earth and has been named the "Einasto Supercluster." It contains the same mass as around 26 quadrillion suns (26 followed by 15 zeroes)."
