Mocha Swirls in Jupiter's Turbulent Atmosphere

During its 36th low pass over Jupiter, NASA's Juno spacecraft captured this view of striking cloud bands and swirls in the giant planet's mid-southern latitudes. The dark, circular vortex near the center of the image is a cyclone that spans roughly 250 miles (about 400 kilometers). The color at its center is likely to be the result of descending winds that cleared out upper-level clouds, revealing darker material below.
