Astronomers are already searching for signs of microscopic alien life on Mars and elsewhere but is there intelligent life in the universe? Are there advanced, technological civilizations like our own on other planets? Many astronomers believe the answer is yes and we may be on the verge of discovering it. Some scientists even think we may have discovered it already! Radioastronomy offers us a chance to listen for alien signals in the cosmos. But how will we prepare for a call from E.T.? And when E.T. does call, should we call back?
