Project BETA: The Search Begins

On the Cover: The Andromeda Galaxy is the nearest spiral galaxy to our own, the Milky Way. Only 2.2 million light-years away, it graphically demonstrates the immensity of galaxies, and feeds our wondering if other planets exist on which a technical civilization exists. The various searches being conducted from Earth mostly concentrate on detecting radio signals from another civilization within the Milky Way. The Planetary Society's Project BETA, now online, is able to search a quarter-billion channels at once, making it the most powerful continuing SETI program on Earth.
