IRIS Movie of the Day
At least once a week a movie of the Sun taken by NASA's Interface Region Imaging Spectrograph (IRIS) is posted by one of the scientists operating the instrument.

At the edge of the Sun, IRIS peers into many small-scale dynamic effects. Thousands of jets are seen "jumping" up and down from the surface. Suddenly, a larger jet towers above all the others, extending far from the surface for only a few minutes. Most of this material then falls back into the surface, part of a mystifying cycle of matter and energy between the solar surface and the extended atmosphere.
