Notable features

Stars

The brightest star in the constellation, γ Velorum, is a bright 1.75m supergiant star. The star is actually quintuple, and the primary component is famous for being the brightest Wolf–Rayet star in the sky. γ Velorum is also sometimes called Regor, which is Roger backwards.

κ Velorum is also called Markeb.

False Cross

The False Cross is an asterism formed of the stars δ Velorum and κ Velorum and ι Carinae and ε Carinae. It is so called because it is sometimes mistaken for the Southern Cross, causing errors in astronavigation.

Deep sky objects

Of the deep sky objects of interest in Vela is a planetary nebula known as the NGC 3132 (nicknamed Eight-burst Nebula). This constellation has 32 more planetary nebulae.

Also of interest 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.

The Gum Nebula is a faint emission nebula, believed to be the remains of a million-year-old supernova.
