Puppis-A Supernova Remnant by Eddie Trimarchi
Via Flickr:
The Puppis-A supernova remnant is the small bluish blob near the centre. It’s an expanding shell about 100 light years in diameter and around 7,000 light years away, with the light first reaching Earth about 3,700 years ago, the star exploded around almost 11,000 years ago.. We see it through the Vela Supernova remnant which is four times closer and resulted from a Supernova in the neighbouring constellation of Vela, about 2,000 earlier.
