The god of thunder appears to have misplaced his helmet in a new deep-space photo from Ronald Brecher, which captured glorious detail in a nebula scene surrounding a colossal star shining 15,000 light-years from Earth in the constellation Canis Major, the "Great Dog".
A pair of wing-like nebula structures sweep away from NGC 2359's central bubble, giving it the appearance of a vast cosmic helmet remarkably similar to that worn by Thor, the Norse god of thunder.
Article continues belowThe burst of activity that formed NGC 2359 — also known as Thor's Helmet — is merely the precursor to the cataclysmic natural light show to follow, when the ageing Wolf-Rayet star ends its life in a supernova explosion that will reshape the nearby interstellar environment.
ZWO ASI533MC Pro 
The ZWO ASI533MC Pro camera is the best dedicated astro camera out there, in our opinion. It features zero amp glow, 80% quantum efficiency and a 20FPS frame rate. It also features a 9MP sensor and you can check out our ZWO ASI533MC Pro review for a more in-depth look.
Brecher captured the ionized glow of the distant nebula using a Celestron 14-inch EDGE HD telescope with a monochrome astronomy camera fitted with a series of narrowband filters in the skies over the city of Guelph,Canada, from March 8-13, 2026.
A little over 8 hours and 124 camera exposures went into the creation of the gorgeous deep space image, which was carefully stacked and processed using the astronomy software PixInsight. "I didn't think I could capture Thor's Helmet from my location," Brecher told Space.com in an email. "It skimmed the trees through my most light-polluted skies, awash in the glow of the Guelph's Auto Mall. But here we are!"
