Explanation: While cruising around Saturn, be on the lookout for picturesque
juxtapositions of moons, rings, and shadows. One quite picturesque arrangement
[6] occurred in 2005 and was captured by the then Saturn-orbiting Cassini [7]
spacecraft. In the featured image, moons Tethys [8]  and Mimas [9] are visible
on either side of Saturn's thin rings [10] , which are seen nearly edge-on.
Across the top of Saturn [11]  are dark shadows [12]  of the wide rings,
exhibiting their impressive complexity. The violet-light image [13]  brings up
the texture of the backdrop: Saturn's clouds [14] . Cassini orbited Saturn
from 2004 [15]  until September of last year, when the robotic spacecraft [16]
 was directed to dive into Saturn to keep it from contaminating any moons [17]
.
