Changes in methane lakes on Titan

A recent article in the New York Times highlighted that during the four years Cassini has been at Saturn, the level of liquid in the methane lakes of the southern hemisphere of Titan have dropped. The methane lakes were originally detected by radar instruments onboard the spacecraft. Because Cassini has had a unique opportunity to study the planet and it's moons over time, the changes can be linked to seasons on Titan.

Saturn's Moons Dione and Titan from Cassini

Q. What would it be like to see a sky with many moons?

A. Totally awesome, it'd be like playing Spore, but I'd still want my terraforming tools :)

Prometheus Remastered

Q: What does Saturn's shepherd moon Prometheus really look like?

A: It looks a lot like a giant, grey space potato. But still, a very dramatic pose.

Saturn's PacMan

The so-nicknamed PacMan on Saturn's moon Mimas imaged with Cassini is just temperature variations over the surface possibly due to different surface materials.
