When imaged by NASA Cassini spacecraft at infrared wavelengths that pierce the planet upper haze layer, the high-speed winds of Saturn atmosphere produce watercolor-like patterns. With no solid surface creating atmospheric drag, winds on Saturn can reach speeds of more than 1,100 miles per hour (1,800 kilometers per hour) -- some of the fastest in the solar system. This view was taken from a vantage point about 28 degrees above Saturn's equator. The image was taken with the Cassini spacecraft wide-angle camera on Dec. 2, 2016, with a combination of spectral filters which preferentially admit…
