Vela
Vela is visible in the southern evening sky in the months around February. The Milky Way runs through it and so it is home to numerous open clusters, including fifteen which are brighter than tenth magnitude.
The stars δ-Vel and κ-Vel, together with Avior and Tureis, form the False Cross, an asterism which is easily mistaken for the nearby Southern Cross in Crux.
Until the eighteenth century, Vela was part of the much larger ancient constellation of Argo Navis, listed by Ptolemy among his 48 constellations in the second century. Argo Navis covered over 4% of the sky, an area 25% larger than the biggest modern constellation, Hydra.
In 1763, Nicolas Louis de Lacaille divided it up into three parts: Carina, Puppis and Vela. As a result of this relatively recent subdivision, the Bayer designations (α, β, γ, etc) are split between the stars of the three constellations.
In classical mythology, Argo Navis was the ship sailed by Jason and the Argonauts on their voyage to recover the golden fleece. Vela represents the ship’s sail.
In Indian astronomy, Vela is known as ನೌಕಾಪಟ (Naukapata)
