Antlia

Antlia is a constellation in the southern sky. Its name means "pump" and it specifically represents an air pump. The constellation was created in the 18th century from an undesignated region of sky, so the stars comprising Antlia are faint. Antlia is bordered by Hydra the sea snake, Pyxis the compass, Vela the sails, and Centaurus the centaur. This group of constellations is prominent in the southern sky in late winter and spring. NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy lie within Antlia's borders.

According to some, the most prominent stars that now comprise Antlia were once included within the ancient constellationArgo Navis, the Ship of the Argonauts, which due to its immense size was split into several smaller constellations by Lacaille in 1763.However, given the faintness and obscurity of its stars, most authorities do not believe that the ancient Greeks included Antlia as part of their classical depiction of Argo Navis.

Because it occupies a part of the celestial sphere that faces away from the Milky Way, Antlia contains very few deep-sky objects. It contains no globular clusters, no planetary nebulae, and no open clusters. However, it does contain several galaxies.[1]


The Antlia Cluster, also known as Abell S0636, is a cluster of galaxies located in the Hydra-Centaurus Supercluster. It is the third nearest to our Local Group after the Virgo Cluster and Fornax Cluster.
