Mars. This year, planetary probes suggest that water was probably present, and some scientists believe that outcroppings like those in the bottom photo hide glaciers of frozen water just beneath the surface near the poles--perhaps a lot of water. This makes life on Mars more of a possibility, at least in its past. Right now, all indications are that it is another dead world.

Have they drilled beneath the surface to discover what conditions existed in the past? Was it always a dead world, I wonder?
