A special episode of How On Earth with Dr. Seth Shostak, the Senior Astronomer at the SETI Institute.
From the site: "We’ve been listening for their tell-tale signal for 50 years with no luck, but Seth says that he’ll bet a cup of coffee we’ll hear from them in the next few decades. We explore what might happen if we find these brainy aliens or if we don’t find them at all. It’s part of the Conference on World Affairs."
