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.
