The most profound question asked by mankind is: are we alone? So the second most profound question must be: where should we look if we're not alone?
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.
"Although there is only a tiny probability that alien technology would have left traces on the moon in the form of an artifact or surface modification of lunar features, this location has the virtue of being close, and of preserving traces for an immense duration," Davies and Wagner say in their paper published in the journal Acta Astronautica (doi:10.1016/j.actaastro.2011.10.022).
