A Pretend Trip Under a Sunspot

This movie takes us on a pretend flight under the "surface" of the Sun. Looping magnetic field lines "break" through the Sun's surface. Dark sunspots form around these bunched up magnetic fields. One loop is split apart. It gives off huge amounts of energy as it causes a "solar storm".
