Saturn's Iapetus: Painted Moon- Vast sections of this strange world are dark as coal, while others are as bright as ice. The composition of the dark material is unknown, but infrared spectra indicate that it possibly contains some dark form of carbon. A leading hypothesis is that the dark material is mostly dirt leftover when relatively warm but dirty ice sublimates.

Io: The Prometheus Plume Credit: Galileo Project, JPL, NASA Two sulfurous eruptions r visible on Jupiter's volcanic moon Io in this color composite image from the robotic Galileo spacecraft that orbited Jupiter from 1995 to 2003. @ the image top, over Io's limb, a bluish plume rises about 140 kilometers above the surface of a volcanic caldera known as Pillan Patera. In the image middle, near the night/day shadow line, the ring shaped Prometheus plume is seen rising about 75 kilometers above
South Polar Vortex Discovered on Titan (July 24 2012) Image Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA What's happening over the south pole of Titan? A vortex of haze appears to be forming, although no one is sure why. The above natural-color image shows the light-colored feature. The vortex was found on images taken last month when the robotic Cassini spacecraft flew by the unusual atmosphere-shrouded moon of Saturn. Cassini was only able to see the southern vortex (...) #astronomy
Iapetus – the black-and-white walnut Moon- Iapetus is the third largest moon of Saturn, This is the equatorial ridge that runs along the center of Cassini Regio; in case you were wondering, the ridge has an average height of 13 km, occasionally going up to 20km, a length of 1,300 km and a width of about 20 km. It was discovered when the Cassini spacecraft imaged Iapetus on December 31, 2004, and even in 2013, it has astronomers baffled.
Enceladus: A Tectonic Feast Credit: NASA/JPL/Space Science Institute NASA's Cassini spacecraft has been studying Saturn and its moons since it entered orbit in 2004. This image, taken on Oct. 5, 2008, is a stunning mosaic of the geologically active Enceladus after a Cassini flyby.
