ATA On The Case

The SETI Institute's Allen Telescope Array is now scanning the star system that could conceivably contain an alien megastructure, searching for possible intelligent radio signals.

The leading explanation for the odd set of transits documented by the Kepler spacecraft is a clump of giant comets, but the alien option must be ruled out, if possible.  ATA won't do that, of course-- the absence of radio signals would not mean a structure is not there-- but the discovery of signals would be quite something.
