“Thor's Helmet” is copyrighted by CXIELO Observatory. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThor's Helmet is an interstellar bubble blown by a fast wind from a massive, hot star at its center. This star is a Wolf-Rayet star, a rare type that sheds its outer layers quickly. The helmet is about 30 light-years across and sits in the constellation Canis Major. It is considered a pre-supernova stage for the central star.
