Vela Super Nova Remnant
Vela Super Nova Remnant: This is the central part of a very extended nebula in a distance of about 1300 LY in the southern constellation of Vela. It was created approx. 11000 years ago, when a giant star blew into pieces in a gigantic super nova explosion relatively near to our solar system. It is embedded in the Gum Nebula and resembles another well known super nova remnant, the Veil Nebula.Like there the shock fronts of the explosion excite interstellar gas to emit radiation.
The image is made up of deep exposures with two narrow band filters for the hydrogen H-alpha and oxygen O[III] emission lines.
The image has been selected as "Astrofoto der Woche" (astrophoto of the week) by astronomie.de
