Looks like false color. The picture shows different angles/positions. Made from a spacecraft orbiting a moon with a quite thin atmosphere. It's not Titan since Titan has a dense atmosphere. I was thinking of Europe, but there is too much detail. A panorama 180 degree picture. Looks like false color. The picture shows different angles/positions.

However it would be methane. On Titan methane exists simalir to water on Earth. Titan is in a spot in the solar system where it has a tempature where methane can exist in liquid, solid, and gaseous states. It would be very intresting to see if there is life that uses methane much like we use water. Most people though have counted out Titan for the search for life in think they should send a probe to see if the is som sort of bacterial or multi-celluler sort of life. Sorry for the ranting. ,Tim DrBill,

I'd rate this as "Average Difficulty". I'm lovin' this feature! Give us a tough one! (The Rachat Structure in Northwestern Africa would snow most.)

An image from Mars would've probably shown better surface resolution. But Titan? Wow - good one. I guessed Venus as well, one of the many Magellan sent back.

Looks like snow on a rocky landscape, but I'm sure it must be something much more exotic. Anybody know what the light and darker areas are made of?

Know how this little game would be even more interesting? If you didn't tell us right away what we're looking at. Let it rest for a few hours, let us sweat down here. And then explain, either in a new post of throug an edit in these. LLDIAZ, the problem with Venus is that we have a very limited stock of surface photos from there, and the topography is wrong for those. Limited stock is also a problem with Titan, of course, but in this case the topography is just right... ;) Oh, and sorry for the double post; I just thought of this.

This was way too easy. If you showed us a picture of Dione, though, or Rhea, or some generic rocky crater field, that would be a real challenge.
