Ben: Do you believe in extra-terrestrials?
Seth Shostak: "Well, Ben, if I didn't, I wouldn't continue to do this work. It would be very frustrating to think that we're looking for something
that doesn't exist."
Duncan: How do you use radios to listen for aliens?
Seth Shostak: "The scheme that we use is to point very large antennas in the directions of sun-like stars, and look for signals that are clearly
produced by a transmitter, and not natural cosmic static."
Sara: What type of signals do you expect aliens to make?
Seth Shostak: "Well, Sara, I expect aliens to make all kinds of signals, but the kind that we look for are so-called narrow-band signals. These are
at one particular spot on the radio dial. These are the types of signals that would be most easy to detect from great distances."
