Vela (the Sail) is a rather large constellation on the southern hemisphere, and together with Carina (the Keel), Puppis (the Stern), and Pyxis (the Compass), it forms the compound constellation Argo Navis.

It has no alpha or beta stars (meaning the brightest stars in a constellation), as it was once part of Argo, and none of the stars have been assigned new names after the separation.

It looks roughly like this:

        _ _ -o _
    o -          O - _
                 |     -O  
                |      | 
 _o             |      |
O _ _          |   _ -o   
      - -o - - O -
