Not to be confused with the SITE Institute.

The SETI Institute is a not-for-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations. It aims for discovery and for sharing knowledge as scientific ambassadors to the public, the press, and the government. SETI stands for the "search for extraterrestrial intelligence". The Institute consists of three primary centers: The Carl Sagan Center, devoted to the study of life in the universe, the Center for Education, focused on astronomy, astrobiology and space science for students and educators, and the Center for Public Outreach, producing "Big Picture Science," the Institute's general science radio show and podcast, and "SETI Talks" weekly colloquium series.
