From a distance Saturn seems to exude an aura of serenity and peace.

In spite of this appearance, Saturn is an active and dynamic world. Its atmosphere is a fast-moving and turbulent place with wind speeds in excess of 1,100 miles per hour (1,800 km per hour) in places. The lack of a solid surface to create drag means that there are fewer features to slow down the wind than on a planet like Earth.

Mimas, to the upper-right of Saturn, has been brightened by a factor of 2 for visibility.
