VDB Ha24 in the Vela SNR – 800 light years distant.
Like a giant cosmic Condor drifting across deep space, this beautiful shockwave of glowing filaments of Ionised Oxygen overlaps the Hydrogen Alpha rich Gum nebula region.
7.2 hrs exposure, using two narrowband filters (Ha & O3) RG & B stars – and Marco Lorenzi Bicolour processing technique.
30mins each RG & B 60 secs

About this Nebula
Within the Eastern section of the Vela Supernova Remnant, the expanding debris cloud is from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago. In addition to the shocked filaments of glowing gas, the cosmic catastrophe also left behind an incredibly dense, rotating stellar core, the Vela Pulsar. Some 800 light-years distant, the Vela remnant is likely embedded in a larger and older supernova remnant, the Gum Nebula. In this narrowband, wide field image, red and blue colours track the characteristic glow of ionised hydrogen (red) and oxygen (blue) atoms. (APOD)
“Supernova remnants are spectacular objects and the Vela SNR is the spectacular showpiece of the region – the remains of a star that blew itself to smithereens around 11,000 years ago.”
