Are Earth's inhabitants the only intelligent life forms in the universe? If life exists elsewhere, would attempts to communicate be discerned across the millions of light years? What means are scientists using to try to reach intelligent life in outer space? Practical Guide to the Universe: Calling All Planets addresses these issues, as host Tom Selleck discusses the possibilities of life throughout the universe. High-powered instruments, such as radio telescopes, continually listen for signals that might indicate a message originating in deep space.
