Cosmic Structure ავტორი polyGeek

My God! It's full of stars. Galaxy filaments, also called supercluster complexes or great walls, are, so far, the largest known cosmic structures in the universe, thread-like structures with a typical length of 50 to 80 megaparsecs h-1 that form the boundaries between large voids in the universe.[3] Filaments consist of gravitationally-bound galaxies; parts where a large number of galaxies are very close to each other are called superclusters. http://en.wikipedia.org/wiki/Galaxy_filament
