The Sloan Great Wall is a giant wall of galaxies which may be 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 (over 8 sextillion miles) 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.
