Dr. Sherwood Githens, a former Sr. Warden at Emmanuel Church, will talk about he methods for first identifying planets that have the right conditions for life as we know it (especially liquid water), some of the possible life-forms that might be encountered (touching on life found in extreme locations on earth, and the history of life on earth), and what signs of life will be sought via telescopes already built and under construction. He will further explore the philosophical and religious meaning of actually finding life on other planets in our solar system or around nearby stars.
