Sloan Great Wall
From Wikipedia, the free encyclopedia
The Sloan Great Wall, a giant wall of galaxies, is the largest known structure in the Universe. Its discovery was announced in October 2003 by J. Richard Gott III, and Mario Juric, both of Princeton University, and their colleagues using data from the Sloan Digital Sky Survey[1]. They measured the structure to be 1.37 billion light years in length (over 8 quintillion miles) and approximately one billion light-years distant.
The Sloan Great Wall is nearly 3 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.
