The Sculptor Wall is a superstructure of
galaxies A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. ...

Milky Way Galaxy The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked ey ...

The superstructure is also called the Southern Great Wall, the Great Southern Wall, or just the Southern Wall, in reference to the CfA2 Great Wall, Northern Great Wall. The structure is 8000 km/s long (where km/s indicates the
