Illustration depicting asteroseismology - the study of oscillations inside stars. Because a star's
different oscillation modes are sensitive to different parts of the star, they inform astronomers
about the internal structure of the star, which is otherwise not directly possible from overall
properties like brightness and surface temperature. The interior of a Sun-like star is shown, with
some oscillation modes superimposed, along with some sound wave trajectories.
