The Sloan Great Wall (SGW) is a cosmic structure formed by a giant wall of galaxies (a galaxy filament). Its discovery was announced from Princeton University on October 20, 2003, by J. Richard Gott III , Mario Jurić , and their colleagues, based on data from the Sloan Digital Sky Survey .
Contains about 56,000 galaxies, located 820 million light years away. BOSS Great Wall (BGW) (2016) 1,000,000,000: Structure consisting of 4 superclusters of galaxies. The mass and volume exceeds the amount of the Sloan Great Wall. [22] Perseus–Pegasus Filament (1985) 1,000,000,000: This galaxy filament contains the Perseus–Pisces Supercluster.
This was the first super-large large-scale structure or pseudo-structure in the universe to be discovered. The CfA Homunculus lies at the heart of the Great Wall, and the Coma Supercluster forms most of the homunculus structure. The Coma Cluster lies at the core.

Nevertheless, when compared to several other chain structures, such as the Sloan Great Wall, the BOSS Great Wall's superclusters are far richer, containing more dense, high stellar mass galaxies. [4] The BOSS Great Wall's discovery, and the data gained therein, should prove very beneficial for astronomers who study the overall structure of the ...
The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).

The Sloan Great Wall, discovered in 2003, has a length of 423 Mpc, [11] which is marginally larger than the homogeneity scale as defined above. The Huge-LQG is three times longer than, and twice as wide as the Yadav et al. upper limit to the homogeneity scale, and has therefore been claimed to challenge our understanding of the universe on ...
