DescriptionComa Wall also known CfA2 Great Wall. This Coma Wall is like a firework. The Great Wall (also called Coma Wall), sometimes specifically referred to as the CfA2 Great Wall, is an immense galaxy filament. It is one of the largest known superstructures in the observable universe.

This structure was discovered c. 1989 by a team of American astronomers led by Margaret J. Geller and John Huchra while analyzing data gathered by the second CfA Redshift Survey of the Center for Astrophysics | Harvard & Smithsonian (CfA). The term Great has been added to distinguish it as an even larger type compared to standard galaxy walls.

The CfA2 Great Wall has the maximum dimensions of either 500 million or 750 million light years depending on the figure and the reference used.[citation needed] It is 200 million light years in width and about 16 million light years in thickness. Its nearest point is about 300 million light years from Earth, while its furthest point is 550 million light years away. It consists of three massive galaxy superclusters: Hercules, Coma, and Leo.

The CfA2 Great Wall includes the Coma Filament.
