Mimas, Dione and the Rings
Cassini continues to send back the most amazing pictures from the Saturn system. Every time I think I’ve seen the most stunning or most beautiful one, they post another one that grabs my attention. This picture shows Mimas (the small dark moon) moving in front of Dione with the rings shown below. You can just make out the curve of the rings at the far right end of the full image (click the image to follow its link to the full version).
The Cassini project also announced yesterday they have strong evidence showing large lakes of liquid hydrocarbons on Titan. I recall one of the more interesting challenges facing the designers of the Hyugens probe was the possbility of landing in a lake. So they made sure the probe could float if required. As it turned out floating wasn’t required, but its nice to think they didn’t waste their time or energy worrying about such a possiblity.
