Vela SNR & Pencil Nebula: 2-panel mosaic
The Vela SNR is a supernova remnant in the southern constellation Vela, the sails.
Its source Type II supernova exploded approximately 11,000–12,300 years ago (and was about 800 light-years away).
On the right, and part of the Vela SNR, the Pencil Nebula (NGC 2736) can be recognized.
