For anyone who is interested in this, I highly recommend listening to the podcast of Richard Pogge's Astronomy 141 course at Ohio State Uni. http://www.astronomy.ohio-state.edu/~pogge/Ast141/#lectures http://www.astronomy.ohio-state.edu/~pogge/Ast141/#lectures (iTunes link: https://itunes.apple.com/us/course/id559775126 https://itunes.apple.com/us/course/id559775126 ) Here's the overview: Astronomy 141, Life in the Universe, is an introduction to Astrobiology. The topics covered in this course lie at the interfaces between astronomy, chemistry, biology, geology, and the earth and planetary sciences. We will learn about scientists' ongoing quest for answers to some of the most fundamental human questions: How did life originate on Earth? Is there life on other worlds? Are we alone in the universe? What is the long-term future of life in the universe?
