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 twin spacecraft, Vela 6A and 6B, were launched on 8 April 1970. Data from the Vela 6 satellites were used to look for correlations between gamma-ray bursts and X-ray events. At least two good candidates were found, GB720514 and GB740723. The X-ray detectors failed on Vela 6B on 27 January 1972 and on Vela 6A on 12 March 1972.
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
HR 3562 (HD 76566) is a visual binary consisting of a bluish-white hued variable star and a Sun-like secondary star in the southern constellation of Vela. It has the variable-star designation IY Velorum (abbreviated to IY Vel). With an apparent magnitude of 6.26, the brighter primary is near the limit for naked eye visibility.
HR 3831, also known as HD 83368, is a triple star system in the southern constellation of Vela at a distance of 233 light years. This object is barely visible to the naked eye as a dim, blue star with an apparent visual magnitude of 6.232. It is approaching the Earth with a heliocentric radial velocity of 4.0 ± 0.3 km/s. [5]
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 ...
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.
