The Sloan Great Wall is a giant wall of galaxies (a galactic filament), which is as of 2009 the largest known structure in the Universe. Its discovery was announced on October 20, 2003 by J. Richard Gott III and Mario Jurić, of Princeton University, and their colleagues, based on data from the Sloan Digital Sky Survey.[1] The wall measures 1.37 billion light years in length and is located approximately one billion light-years from Earth.
The Sloan Great Wall is nearly three times longer than the Great Wall of galaxies, the previous record-holder, which was discovered by Margaret Geller and John Huchra of Harvard in 1989.
The Sloan Great Wall is classified as hypercluster SCl 126 in SIMBAD.[2]
