Forty-two radio dishes of the Allen Telescope Array at the Hat Creek Radio Observatory in Hat Creek, Calif. point to the skies collecting scientific data in the search for signs of intelligent life in the universe on April 29, 2008. Each dish is about 20-feet in diameter. The dishes at right are pointed straight up. Scientists can control the direction of each individual dish. (Gary Reyes/Mercury News)
