[1] The Southern Supercluster connects to the Telescopium−Grus Cloud through the Cetus-Aries Cloud, a minor filament that was identified and described in 1987 by astronomer Brent Tully with colleague Richard Fisher in his book The Nearby Galaxies Atlas.

[12] In 1847, John Herschel had pointed out the existence of a stream of galaxies or nebulae as they were known at the time in the constellations of Cetus, Fornax, Eridanus, Horologium, and Dorado.

Later in 1953 Gérard de Vaucouleurs recognized this band as a supercluster[1] dubbing it the ''southern supergalaxy'',[13] with many of the groups and clusters being identified by around 1975.

[14] In 1987, astronomer Brent Tully with colleague Richard Fisher identified in his book The Nearby Galaxies Atlas the Cetus-Aries Cloud, a nearby minor filament that was described as being a connection between the Southern Supercluster and the Telescopium−Grus Cloud, another filament that was identified by the same authors that year.

[9] However, Brent Tully considers the Antlia Cloud to be part of the Virgo Supercluster.
