Now, two prominent scientists have published a paper suggesting that although we have an entire universe to seek out the proverbial alien needle in a haystack, perhaps looking in our own backyard would be a good place to start.
Paul Davies and Robert Wagner of Arizona State University have suggested a crowd-sourcing effort to find artificial structures on the moon. After all, lunar missions like NASA's Lunar Reconnaissance Orbiter are returning some dazzling, high-resolution imagery of the moon's surface. If aliens have been there, perhaps we could spot evidence of their presence.
They raise perfectly logical points. The moon is close enough to be reached, evidence would be preserved because of the lack of atmosphere. If aliens decided to check us out, the moon would make an excellent place to play peek-a-boo. Unless they went through extraordinary lengths to cover their footprints something would remain.
It's intriguing, and I would happily donate processor time to lend a hand. As it sometimes happens, the logical starting place was right in front of us all along.
