Cosmic Company (with Alex Barnett) [2003]

In Cosmic Company, Seth Shostak and Alex Barnett ponder the possibility of aliens visiting the Earth, as well as the consequences of receiving a signal from the cosmos proving we're neither alone, nor the most intelligent life forms. They explain why scientists think life might exist on other worlds, and how we might contact it. Seth and Alex, experienced writers of popular astronomy, provide an accessible overview of the science and technology behind the search for life in the universe.
