They are very similar, but you made it easy by leaving the filenames alone. Just by hovering my mouse above each picture I could see that the first picture is Mercury and the second one the moon.

D'OH!

well, maybe not everyone will notice that immediately!

ok, now that little problem is fixed... and i may or may not have shuffled the order of the images! so everyone can still guess ;)

The one with the terminator is the Moon; the other is Mercury. (Hint: there are certain features that the Moon has that Mercury does not - at least not in anything we've imaged so far.)

I agree with Kevin. Also, I think you can see things on Mercury that aren't on the Moon, in that photo.

I agree with Kevin. I think you can also see things on Mercury that aren't on the Moon, in those photos.

I agree with Kevin about the second piture, but the first... Maybe the moon or... is it Merccury too? The top of the picture says to me that is the Moon.
I´m sorry for my terrible English.

No clue; I'm confused.

Well, I've just been trolling through pictures of both for my last blog post, but the moon picture has some dark, crater-free mare, and lunar craters are generally deeper and more likely to have central peaks than are mercury craters.

On the image of Mercury, what is up with the image artifact that resembles an out gassing event on the bottom left of the disk?

When do you plan to announce the answer? (Just wondering)

thanks for asking! i plan to announce the answer soon... i've been swamped with job interviews, finalizing my defense date, and teaching... sorry for the delay!!

x-ray... i think the plume-like thing that you identify is actually part of the surface. it looks like the surrounding regions might be lower, so that the only part of the surface receiving sunlight is the little pathway running between the crater rims. anyone else see that?

ANSWERS: the moon is the top image and mercury is the lower image.

Government should support and encourage more such kind of a project in near future.
