The Vela Supernova Remnant is a an exceptionally large structure (spanning ca. 8° of the night sky) which resulted from a Type II supernova explosion approximately 11.000 years ago. Being only 900 light years away it is one of the closest supernova remnants. The details in the image result from hydrogen-alpha (red), sulphur-II (yellow) and oxygen-III (blue) emissions. The image was completed using data from a remote hosting facility in Chile.
