NASA’s Interface Region Imaging Spectrometer, or IRIS, peers into a lower level of the Sun’s atmosphere — called the interface region — to determine how this area drives constant changes in the Sun’s outer atmosphere.

The interface region feeds solar material into the corona and solar wind: In this video, captured on Sept. 10, 2017, jets of solar material appear like tadpoles swimming down toward the Sun’s surface. These structures — called supra-arcade downflows — are sometimes observed in the corona during solar flares, and this particular set was associated with the X8.2 flare of the same day.
