Helioseismology In 1962, physicists at Cal Tech discovered that the surface of the Sun vibrates due to the violent nuclear reactions that roil within its core. This has led to a new field of solar science known as helioseismology. Atypical vibration of the Sun is shown in the figure(Figure 1): it has a period of 5.8 minutes.
