Mars

This close up was taken by none other than the Mars Raconnaissance Orbiter. Home plate is the general area where Spirit, Opportunity, and any future mission to Mars would land.
I picked this image because of a recent rumor I heard saying that liquid water was found on Mars. Although I doubt that this is all true, if there was liquid on Mars, there's no way it would be water. I think it would be methane or any one of those other gasses.

Spokes in Saturn's Rings

These are the pictures of spokes taken in early 1980s by Voyager. They were not seen by Cassini, and there is no sure theory on what they are. It is believed they are caused by electromagnetic charge caused perhaps by meteors crashing into the rings.
