I probably noticed the nice photo of Dione when it appeared on the Cassini raw images page two months ago, but I know I didn't notice the little speck below and to the left of the bigger moon. That speck is a small moon, Telesto.

Cassini VIMS sees the long-awaited glint off a Titan lake

Posted by Emily Lakdawalla on 2009/12/17 04:28 CST
