I'll reveal what it is after the contest. This is a macro picture.

It’s looks like a monster’s hand, isn’t it?

The remarkable islands of the strange blue planet circling Canopus Zeta. That's one really strange planet - it's parabolic! Those are actually ice crystals clustered around the airhole in an airplane window; the picture was turned on its side for effect

Atolls and reefs in the green seas of Mare Supercilius, Menoxil 5.

Tree bark, green from algae. The tiny waves are minute ridges in the wood catching the oblique sunlight. Oh, and the picture was turned sideways for effect. Some of the other trees in the neighborhood looked like tiny farms with fields, but I prefer seas to farmland.
