Ten Best Pictures From NASA's Cassini Probe
Saturn casts a long shadow across its icy rings in a 2007 picture taken by NASA's Cassini-Huygens spacecraft—an unattainable perspective from Earth's line of sight. The picture is among Cassini's ten best, chosen by National Geographic News photo editors to mark the probe's anniversary.
Jupiter's volcanic moon Io spins against the backdrop of its parent planet in 2001. Cassini snapped the image as the craft swung past the gas giant en route to the Saturnian system.
Saturn's concentric rings—and the gaps in those rings—stand out in unprecedented detail in this 2008 natural-color picture taken by Cassini.
From less than 39,000 miles (63,000 kilometers) away, Cassini snapped the first ever picture of Saturn's highly pitted moon Hyperion (pictured) in 2005.
(on a side note, the first server I ever built up as a professional system admin, I named Hyperion after this moon. It was an Windows NT domain controller)
Saturn's rings cast a razor-thin shadow on the planet in a 2009 Cassini picture.

While cruising by Saturn in February 2007, Cassini captured a series of haze-penetrating infrared images, which were combined to create this false-color mosaic.
Saturn's heavily cratered moon Mimas seems to hover over its home planet in a 2007 Cassini image.
Smoggy, golden Titan, Saturn's largest moon, is set against the backdrop of the giant planet in May 2012.
"Tiger stripes" on Saturn's moon Enceladus (pictured) are seen in an enhanced-color mosaic created with Cassini images taken in 2005.
