Seth leads the effort in trying to find evidence of intelligent life in space. He is also committed to getting the public, especially young people, excited about astrobiology and science in general. Seth also is the host of “Big Picture Science,” the SETI Institute’s weekly radio show. The one-hour program uses interviews with leading researchers and lively and intelligent storytelling to tackle such big questions as: What came before the big bang? How does memory work? Will our descendants be human or machine? What’s the origin of humor? Big Picture Science can be found in iTunes and other podcast sites.
