Description

Thor’s Helmet - The name of this nebula stems from its striking resemblance to the helmet of the famed Norse God of thunder and lightning. It is an emission nebula with an ionized HII region in the constellation Canis Major and lies about 15,000 light-years away from Earth. We can take a closer look at Thor’s Helmet by collecting long exposure images that uncover the bright emission gases in visible light. It is catalogued as NGC 2359 and spans roughly 30 light-years across, appearing as an interstellar bubble that has been inflated by a central Wolf-Rayet star.
