Soft swirls seen by Cassini
From 700,000 miles above the planet's surface, Cassini photographed subtle, multi-hued bands of swirling clouds in Saturn's northern hemisphere at the end of August 2017. "This view looks toward the terminator — the dividing line between night and day — at lower left. The sun shines at low angles along this boundary, in places highlighting vertical structure in the clouds. Some vertical relief is apparent in this view, with higher clouds casting shadows over those at lower altitude," NASA explains.
