Thor's Helmet is a
complex nebula illuminated by a bright rare Wolf-Rayet type star
located about 15,000 light years from Earth. High-velocity
stellar winds from this energetic star compress, excite, and
illuminate surrounding gas and dust to create a bubble of
illumination, similar to the process seen in the Bubble Nebula.
