The Thor’s Helmet Nebula (NGC 2359) in the constellation of Canis Major (The Great Dog)

This chart shows the location of the Thor’s Helmet Nebula (NGC 2359, marked with a red circle). This unusual object was observed using the VLT on the occasion of ESO’s 50th Anniversary, 5 October 2012, with the help of Brigitte Bailleul — winner of the Tweet Your Way to the VLT! competition. The observations were broadcast live over the internet from the Paranal Observatory in Chile. It can be seen as a large, but faint, glow in moderate-sized amateur telescopes.
