[Tuesday, November 13, 2007] The auroral radio emission of giant planets are usually used to estimate their rate of internal rotation. But in the case of Saturn, these emissions present important variations at the month scale, which cannot be due to the rotation.

[Wednesday, November 28, 2007] From a low angle above Saturn's rings, the Cassini spacecraft¿s view of an icy moon is partly obscured. The view looks toward Enceladus across the unilluminated side of the rings from less than a degree above the ringplane.

»» Filtering the Sun
[Wednesday, November 28, 2007] Janus coasts past as the Cassini spacecraft takes in a view of the unilluminated side of the rings. Bright regions within the rings appear so because they allow scattered sunlight to filter through.

»» Saturnian Citizens
[Wednesday, November 28, 2007] Cassini spies two icy denizens of the Saturn System as they hurtle past. The view captures Mimas (397 kilometers, or 247 miles across) at bottom, with Epimetheus (116 kilometers, or 72 miles across) about 48,000 kilometers (30,000 miles) farther beyond.

»» Collapsed Rings
[Wednesday, November 28, 2007] A lone moon coasts along in this view, which was taken from less than a degree below Saturn's sunlit ringplane. The rings are squashed into a narrow band from this viewing angle, foreshortening all of their radial features.

»» Dark Belt of Tethys
[Wednesday, November 28, 2007] Around the equator on its leading side, Tethys wears a band of slightly darker surface material. Cassini imaging scientists suspect that the darkened region may represent an area of less contaminated ice.

»» Scratches on Dione
[Wednesday, November 28, 2007] Bright, wispy fractures streak across Dione's trailing side. Following the Voyager flybys of the early 1980s, scientists considered the possibility that the streaks were bright material extruded by cryovolcanism.

»» A Fresh Face
[Wednesday, November 28, 2007] The leading hemisphere of Enceladus displays a remarkably fresh-looking surface in this recent Cassini view. At this resolution, only a few craters can be made out in this wrinkled region of the geologically active moon's surface.

»» Facing Dione
[Wednesday, November 28, 2007] Canyons slink southward on Dione, while bright-walled craters gleam in the sun. The Cassini spacecraft imaged this same region from a more southerly viewpoint during an approach earlier this year.

»» Dark Lowlands on Titan
[Wednesday, November 28, 2007] Through the obscuring haze come glimpses of Titan's dune seas. The dark, equatorial region known as Shangri-la is visible. Radar images show that Shangri-la and other dark regions around the moon's middle are filled with vast stretches of parallel dunes

»» Solar System in Miniature
[Wednesday, November 28, 2007] Saturn's icy satellites wheel about the colorful giant planet, while the rings shine dimly in scattered sunlight. The Ringed Planet is, in many ways, a laboratory for investigating the history of our solar system and how planets form around other stars.
