Squiggly Saturnian Clouds
Friday, March 30, 2018: Squiggly clouds swirl on Saturn's south polar vortex in this false-color view from NASA's Cassini spacecraft. A ring of high-altitude clouds circles around a dark region where convective storms are raging in Saturn's atmosphere. Citizen scientist Kevin Gill created this colorized image using raw data from Cassini. When Cassini captured the image on July 14, 2008, the spacecraft was approximately 243,000 miles (392,000 kilometers) from Saturn. — Hanneke Weitering
