A projection of the South Pole Wall in celestial coordinates. The South Pole Wall (SPW or The South Pole Wall) is a massive cosmic structure formed by a giant wall of galaxies (a galaxy filament) that extends across at least 1.37 billion light-years of space, the nearest light (and consequently part) [a] of which is aged about half a billion light-years.
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.
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]
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 .
After 24 years in the Aggie Softball Complex, the Texas A&M University System Board of Regents approved construction of a new home for Aggie Softball in April 2016. This construction took the form of the Davis Diamond complex.
This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3] Due to different techniques, each figure listed on the galaxies has varying degrees of confidence in them.
The BOSS Great Wall is one of the largest superstructures in the observable universe, [2] though there are even larger structures known. This figure shows the superclusters of the BOSS Great Wall, on Cartesian coordinates. The large complex has a mean redshift of z ~ 0.47 (z times Hubble length ≈ 6.8 billion light years). [1]
A team of international astronomers recently announced the largest superstructure in the known universe. The immense structure named "Quipu" is estimated to stretch for an astonishing 1.4 billion ...
