NB: Besides being the 226th anniversary of the storming of the Bastille, July 14, 2015 is the date projected for when New Horizons will fly by Pluto. (Full disclosure: I didn't know that; had to Google.)

Yes, the naturally coldest spot ever measured in the solar system is on our moon. But that’s just because we haven’t looked very hard elsewhere.
I expect that to change soon after July 14, 2015 … if not before.

Ice on the closest planet to the Sun? I never even considered the possibility, but it makes sense, in a way. Didn’t recent observations of the Moon show the coldest known spot in the solar system to be in a polar crater?
