On the Cover:
Clouds of stars fill the night sky near the center of the Milky Way. Among the hundreds of billions of stars that make up our galaxy, there may be some that have nurtured life-forms similar in technological development to ourselves—that may be aiming radio beacons in our direction. This is the hypothesis behind Project META, The Planetary Society's search for the radio signals that could tell us that extraterrestrial beings exist.
