Galaxy

A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. The word galaxy is derived from the Greek galaxias , literally "milky", a...

Galaxy filament

In physical cosmology, galaxy filaments, also called supercluster complexes or great walls, are, so far, the largest known cosmic structures in the universe. They are massive, thread-like structures with a typical length of 50 to 80 megaparsecs h-1 that form the boundaries between large voids in...

 of approximately z=0.03), also known as the Sculptor superclusters.

The superstructure is also called "Southern Great Wall", "Great Southern Wall", "Southern Wall", in reference to the Northern Great Wall, or just "Great Wall" — the CfA2 Great Wall. The structure is 8000 km/s long, 5000 km/s wide, 1000 km/s deep, in redshift space dimensions.
