EP14 Astrophysicist Jill Tarter on SETI and Technosignatures

Astrophysicist Jill Tarter talks with host Jim Rutt about the Search for Extraterrestrial Intelligence (SETI), technosignatures + related projects. Starting with the Fermi Paradox and the Drake Equation, they discuss the hunt for life in the universe. While discussing the SETI protocol for determining when a credible signal has been received, Jill Tarter describes the "false positive" incident in 1998 that nearly lead to the announcement that Earth had been contacted by aliens. The two scientists then discuss the state of the art in astrophysics, including extremophiles, exoplanets, Breakthrough Listen, PANOSETI and Laser SETI -- a camera array in 12 locations with 8 cameras per location that should be able to observe the entire sky 100% of the time!
