Vela (pronounced /ˈviːlə/, Latin: sails) is a southern constellation, one of the four parts into which Argo Navis was split (the others being Carina, Puppis and Pyxis).

The brightest star in the constellation, γ Velorum, is a bright 1.75m supergiant star. The star is actually quintuple, the primary component is famous for being the brightest Wolf-Rayet star in the sky.
κ Velorum is also called Markeb.
Of the deep sky objects of interest in Vela is a planetary nebula known as the NGC 3132 (nicknamed Eight-burst nebula). Also of interest within the constellation is the Vela Supernova Remnant. This is the nebula of a supernova explosion which is believed to have been visible from the Earth around 10,000 years ago. The remnant contains a pulsar which was the first pulsar to be identified optically.
Vela is one of the four constellations that made up the old constellation of Argo Navis, the ship of the Argonauts: Vela is the sail.
The False Cross is an asterism formed of the stars δ Velorum and κ Velorum and ι Carinae and ε Carinae. It is sometimes mistaken for the Southern Cross, causing errors in astronavigation.
