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.

On 17 July 2017, IRIS observed an active region at the solar limb. Many bright eruptions are seen at the bottom of the movie, as large amounts of energy are released during a complex solar flare. At the same time, beyond the solar limb many loops are seen, mostly made of plasma that is cooling down and falling back into the surface, a phenomenon know as "coronal rain".
