SETI's Jill Tarter has devoted her career to hunting for signs of sentient beings elsewhere, and almost all aspects of this field have been affected by her work. Astronomer Jill Tarter was the long-time director of the SETI (Search for Extraterrestrial Intelligence) Institute's Center for SETI Research, and also holder of the Bernard M. Oliver Chair for SETI. She led Project Phoenix, a decade-long SETI scrutiny of about 750 nearby star systems, using telescopes in Australia, West Virginia and Puerto Rico.
