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).
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. Pisces–Cetus Supercluster Complex (1987) 1,000,000,000
Aquila also holds some extragalactic objects. One of them is what may be the largest single mass concentration of galaxies in the Universe known, the Hercules–Corona Borealis Great Wall. It was discovered in November 2013, and has the size of 10 billion light years. It is the biggest and the most massive structure in the Universe known.
In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...
The Sloan Great Wall is between 1.8–2.7 times longer than the CfA2 Great Wall of galaxies (discovered by Margaret Geller and John Huchra of Harvard University in 1989). [2] It also contains several galactic superclusters, the largest and richest of which is named SCl 126. This is located in the highest density region of the structure. [3] [4]
Boötes is a constellation bordered by Virgo to the south, Coma Berenices and Canes Venatici to the west, Ursa Major to the northwest, Draco to the northeast, and Hercules, Corona Borealis and Serpens Caput to the east.
The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies [4] some 500 million light-years distant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies. [5] The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure. [6]
Abell 2162 in the nearby constellation Corona Borealis is also a member. [6] The Hercules Superclusters are near the Coma Supercluster, helping make up part of the CfA2 Great Wall. [7] In the 1930s, Harlow Shapley studied the structure of the distribution of galaxies in the constellation of Hercules, and was probably first to discover the ...
