This annotated composite image depicts the movement of the polar and circumpolar cyclones of Jupiter's south pole between 2016 (left) and 2021 (right) as seen by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA's Juno spacecraft. In both images, five cyclones are arranged as a pentagon, with a sixth cyclone in the center (south pole).

JIRAM "sees" in infrared light not visible to the human eye. It was designed to capture the infrared light emerging from deep inside Jupiter, probing the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiter's cloud tops.
