Massive stars play an important role in many astrophysical environments, such as star formation and the structure of the interstellar medium in galaxies. However, the structures and mass loss of massive stars are still mysteries. Global radiation hydrodynamic simulations of an 80 solar mass star envelope were performed on Mira to find the answers. Convection around the iron opacity peak region causes the turbulent structures seen here. Density is highest in the yellow region near the core of the star. Low density wind is launched near the surface. Credits: Science: Yan-Fei Jian, Lars Bildsten and Omer Blaes, University of California at Santa Barbara. Matteo Cantiollo, Flatiron Institute.
