The Elusive Wow tells the story of the Wow! signal—one of the most intriguing radio signals ever seen by searches for broadcasts from the stars. Author Robert Gray reports on the original detection and tells of his searches for the signal, showing examples of what searchers see with interstellar radios. In addition to telling the tale of the elusive signal, Gray surveys the Search for Extraterrestrial Intelligence, also known as SETI—explaining why many scientists think Others might exist on other worlds and how we might find them. Gray´s scientific work has appeared in journals such as Astrophysical Journal and Icarus, and in magazines like Sky & Telescope.
