Vela is bordered by Antlia and Pyxis to the north, Puppis to the northwest, Carina to the south and southwest, and Centaurus to the east. Covering 500 square degrees, it ranks 32nd of the 88 modern constellations in size. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "Vel". [2]
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.
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] It was discovered by John Herschel on March 15, 1836. [3]
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 .
A diagram of a typical nautical sextant, a tool used in celestial navigation to measure the angle between two objects viewed by means of its optical sight. Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the ...
NGC 2736 (also known as the Pencil Nebula) is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula's linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from the Solar System. It is thought to be formed from part of the shock wave of the ...
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 star local neighborhood within 1000 parsecs; the Sun is at the center. The Vela dark clouds is at 270° galactic longitude, bottom-center. The Milky Way in the direction of the Vela Molecular Ridge presents an overlap of objects and structures, all roughly aligned with the galactic plane; situations of this kind may tend to hinder the observation of large nebulae regions, due to the ...
