The Search for Extraterrestrial Intelligence — or SETI — goes beyond hunting for E.T. and habitable planets. Scientists in the field are using telescopes and satellites looking for signs of outright civilizational intelligence. One of the founding pioneers in this search is astronomer Jill Tarter. She is a cofounder of the SETI Institute and was an inspiration for Jodie Foster’s character in the movie Contact, based on the novel by Carl Sagan. To speak with Tarter is to begin to grasp the creative majesty of SETI and what’s relevant now in the ancient question: “Are we alone in the universe?”
