NGC2359 Thor's Helmet Nebula 2000x1720

The nebula is in Canis Major approx. 15000ly away and is approx. 30ly wide. The nebula is more like a bubble inflated by fast winds emanating from the Wolf-Rayet star at the center. This star is thought to be in a brief pre-supernova stage of its evolution. The blueish green colour shows that there is a strong oxygen emission from this nebula.
