| ABSTRACT | NGC 2359, better known as the Thor Helmet nebula, is actually more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble center sweeps through a surrounding molecular cloud. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. It lies about 15,000 light years from Earth in the constellation Canis Major, measuring about 30 light years. This image of the Thor Helmet nebula or NGC 2359 was obtained using the Wide Field Camera on the Isaac Newton Telescope (INT). It is a three-colour composite made from data collected using filters to isolate the light emitted by hydrogen alpha (H-alpha), doubly-ionised oxygen (OIII) and single-ionised sulfur (SII) atoms, and coded in the image as red, green and blue respectively. |
