Sloan Great Wall

(SGW)
(large slab of galaxies discovered in SDSS)

The Sloan Great Wall (SGW) is an element of the large scale structure, discovered in 2003 in the Sloan Digital Sky Survey. It is a billion light-years away, is 1.3 billion light-years across and appears in the southern sky, within the constellations Corvus, Hydra, and Centaurus. It includes several superclusters. It displaced the Great Wall as the largest known structure in the universe and was surpassed by the 2013 discovery of the Hercules-Corona Borealis Great Wall. It has been suggested the SGW is not a single structure but three structures in alignment.
