Thor's Helmet Nebula
NGC 2359 in Canis Major
is fueled by a rare Wolf-Rayet star. W-Rs are incredibly hot, and expel their outer layers of gas at tremendous velocities.
Thor's star HD 56925 has blown multiple bubbles of ionized gas, resulting in a 'helmet' of both OIII (Oxygen 3) teal and Ha (Hydrogen alpha) pink.
Thanks to Martin Pugh for acquiring and calibrating this fine data.
