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 ...
In solar physics, a prominence, sometimes referred to as a filament, [a] is a large plasma and magnetic field structure extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the much brighter photosphere , and extend outwards into the solar corona .
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: Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member ...
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.
The word filament, which is descended from Latin filum meaning "thread", is used in English for a variety of thread-like structures, including: Astronomy [ edit ]
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a ...
A massive galaxy filament, called the Norma Wall (also called Great Attractor Wall [11]) is located at the center of the supposed position of the Great Attractor. The Norma Wall contains the clusters Pavo II , Norma , Centaurus-Crux and CIZA J1324.7−5736 .
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. [1]
