There are hundreds of billions of stars in our galaxy. And in the last year, scientists have discovered thousands (yes, thousands!) of planets beyond our solar system orbiting many of those stars. So is it reasonable to assume some of those worlds support intelligent life - intelligent life that’s trying to find company in the cosmos? That’s what scientist Jill Tarter hopes. She’s the outgoing director of the Mountain View, California-based Center for the Search for Extraterrestrial Life, or SETI. Tarter has spent much of her adult life planning efforts to find signals from a distant civilization. I talked to her about her work and why she remains so hopeful that humanity will eventually find intelligent life out there despite decades of looking.
