The Vela-Puppis Supernova Remnant complex – Brian Boyle

The Vela-Puppis supernova remnant (SNR) passes overhead in Otago during late summer. Named after the constellations of the Keel and the Poop Deck in which it lies, this SNR one of the most spectacular regions of the southern sky. The complex actually contains the remnants of the three different supernova whose progenitor stars exploded between 500 and 12000 years ago. The supernova remnant from 12000 years ago is the most extensive in this picture, and is located relatively close to Earth, about 800 light years distant. This image was taken in the light of ionised hydrogen (red), silicon (green) and oxygen (blue) atoms. The diaphanous expanding shells of the supernova remnant are clearly delineated by the ionised oxygen, many of which are sufficiently remarkable to have their own names such the Pencil nebula and the Blue Chilli nebula. Can you spot them?
