SH2_2 298 - Thors Helmet Nebula

The Thor’s Helmet Nebula (SH2-298) is a distinctive emission nebula located approximately 15,000 light-years away in the constellation Canis Major. Its unique shape, resembling the mythical helmet of Thor, is formed by the interaction between the strong winds and radiation from a central, dying star and the surrounding gas and dust. The nebula is a site of active star formation and features intricate structures of ionized gas, providing valuable insights into the life cycle of stars and the dynamics of nebulae. SH2-298 is a notable example of a stellar remnant nebula, offering key information on the processes that shape the evolution of such regions.
