Two Storm Views on Saturn

Two false-color views of Saturn show detailed patterns that change during one Saturn day within a huge storm in the planet's Northern Hemisphere. The dramatic colors arise from a false-color combination of images taken by the Cassini spacecraft narrow-angle camera: images filtered at 889 nanometers are projected as blue, images filtered at 727 nanometers are projected as green, and images filtered at 750 nanometers are projected as red.

Cassini scientists study the fine details contained in these mosaics to learn about wind speeds and cloud depths in the storm. For example, a red curlicue that indicates a deep cloud is present in the top mosaic, but it does not appear in bottom mosaic taken 11 hours later.
