Great Wall

(Coma Wall, CfA2 Great Wall)
(large slab of galaxies)

The Great Wall is a large scale structure element (a galaxy wall) discovered in 1989 in the CfA Redshift Survey. It is 300 million light-years' distant and spans 500 million light-years by 200 million light-years by 16 million light-years. Across the sky, it is a long area, diagonally spanning hours 8 to 17 and about 0 to +50 degrees declination. It includes the Hercules Supercluster, the Coma Supercluster and the Leo Cluster.

Other larger structures ("great walls") have been discovered since such as the Sloan Great Wall and the Hercules-Corona Borealis Great Wall.
