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. 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.
