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.
