Term Definition
Vela The Sail
A large southern constellation, which is one of the four parts into which Nicolas L. de Lacaille divided the ancient constellation Argo Navis. It lies in part of the Milky Way rich with faint nebulosity and contains ten stars brighter than fourth magnitude. The stars Delta δ and Kappa κ, together with Iota ι and Epsilon ε Carinae, make an asterism known as the false cross since it is sometimes confused with the constellation Crux, the true Southern Cross.
