Vela is a constellation in the southern sky, which contains the Vela Supercluster. Its name is Latin for the sails of a ship, and it was originally part of a larger constellation, the ship Argo Navis , which was later divided into three parts, the others being Carina and Puppis .
The Vela supernova remnant includes NGC 2736. Viewed from Earth, the Vela supernova remnant overlaps the Puppis A supernova remnant, which is four times more distant. Both the Puppis and Vela remnants are among the largest and brightest features in the X-ray sky. The Vela supernova remnant is one of the closest known to us.
For this reason, RX J0852.0−4622 is often referred to as Vela Junior (Vela Jr.). [ 1 ] [ 2 ] There have been a minority of suggestions that the remnant may be a spurious identification of a complicated substructure within the larger and better studied Vela SNR, but most studies accept that G266.2−1.2 is a SNR in its own right.
Psi Velorum, Latinized from ψ Velorum, is a binary star system in the southern constellation of Vela. Based upon an annual parallax shift of 53.15 mas as seen from Earth, it is located 61.4 light years from the Sun. It is visible to the naked eye with a combined apparent visual magnitude of +3.58.

The Vela Supercluster [1] (Vela SCl, VSCL) is a massive galactic supercluster about 265.5 megaparsecs (870 million light-years) [1] away within the vicinity of the Zone of Avoidance, centered on the constellation Vela. It is one of the largest structures found in the universe, covering about 25 × 20 degrees of the sky.
Gamma ray and optical (visible light) light curves for the pulsar, adapted from Spolon et al. (2019) [3]. Vela is the brightest pulsar (at radio frequencies) in the sky and spins 11 times per second [4] (i.e. a period of 89.33 milliseconds—the shortest known at the time of its discovery) and the remnant from the supernova explosion is estimated to be travelling outwards at 1,200 km/s (750 mi ...
Map of the Vela Molecular Ridge. The Vela Molecular Ridge appears as a sequence of bright and dark nebulae, located on the northwestern side of Vela.The main sequence of nebulae that compose it is located a few degrees northwest of the star Lambda Velorum, while some dark ramifications also extend south of it, reaching the central areas of the constellation.
Phi Velorum (φ Vel, φ Velorum) is a star in the constellation Vela. It is a blue-white B-type supergiant with an apparent magnitude of +3.53. It is approximately 1,590 light years from Earth .
