Over 30 years of helioseismology observations from space have revealed how the Sun's magnetic field is created and moves from deep inside to the surface. Scientists found that surface flow patterns, called torsional oscillations, actually begin deep in the Sun, supporting a key theory about the solar magnetic cycle. These findings help explain the Sun’s 22-year activity cycle and show how flows and heat near the surface also change over time. Continued long-term observations are important to improve our understanding of the Sun.
