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.
Delta A has a magnitude of 1.99 and is an eclipsing binary composed of two A-type white stars (Delta Aa and Ab) which orbit each other every 45.2 days and lie 0.5 AU from each other, with a resulting drop in magnitude of 0.4 when the dimmer one passes.in front of the brighter. Delta B is a 5.1 magnitude yellow G-class star of similar dimensions ...
eso 263- g 040, am 1026-442, iras 10268-4423, mcg-07-22-015, pgc 30868 [1] NGC 3261 is a barred spiral galaxy in the constellation Vela . The galaxy lies about 110 million light years away from Earth based on redshift, which means, given its apparent dimensions, that NGC 3261 is approximately 130,000 light years across. [ 1 ]
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 .
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.
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.
Vela 1A was a spin-stabilized 124-kg satellite comprising the first launch in a series of six Vela launches. Together with its twin Vela 1B, their objectives were to monitor nuclear weapons explosions in space and to study x-rays, gamma-rays, neutrons, and charged particles as the satellites passed through interplanetary space, the bow shock, the magnetosheath, and the magnetotail.
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.
