Thor's Helmet is one of the most interesting nebulas in canis Major is Thor's Helmet. This nebula is 15,000 light-years away from us, approx 30 light-years across. The helmet part is more like a bubble expanding from a massive star near the center.  This star, known as a Wolf-Rayet star, a pre supernova star fluffing off an incredable amount of material.  This nova is a 12.5 in magnitude.  We're very pleased we could get it.
