Detailed Cloud Features on Saturn - Universe Today
This image of Saturn shows the giant planet's southwest edge, and a hint of thread-like cloud features. The edge of the planet looks smooth, but right at the terminator (the edge between light and dark), it's possible to see these cloud features. The long shadows make the height differences in the clouds visible. Cassini took this image on October 30, 2005 when the spacecraft was 401,000 kilometers (249,000 miles) from Saturn.
