SETI Institute is a non-profit research organization, located in the Silicon Valley close to the NASA Ames Research Center. Our mission is to lead humanity's quest to understand the origins and prevalence of life and intelligence in the universe and share that knowledge with the world.
SETI Institute began small, with just one project – NASA’s SETI program – and two employees, founder Tom Pierson (a former grants administrator at San Francisco State University), and astronomer Jill Tarter. Over the years, other research disciplines have been added to the Institute’s portfolio, all unified by their relevance to the search for, and understanding of, life beyond Earth. Today, the Institute has approximately 100 scientists as well as specialists in administration, education, and outreach.
