Cassini: Rings are remants of Secessionist Moons!

Just wanted to laugh at my own preoccupations and post a cool picture from the Cassini probe around Saturn.



Saturn's Rings, Cold and Colder
September 2, 2004

The varying temperatures of Saturn's rings are depicted here in this false-color image from the Cassini spacecraft.

This image represents the most detailed look to date at the temperature of Saturn's rings. The image was made from data taken by Cassini's composite infrared spectrometer instrument.

The data show that the opaque region of the rings, like the outer A ring (on the far right) and the middle B ring, are cooler, while more transparent sections, like the Cassini Division (in red just inside the A ring) or the inner C ring (shown in yellow and red), are relatively warmer.
