Astrophysicist Adam Frankjoins us to discuss his new book, "Light of the Stars: Alien Worlds and the Fate of the Earth." Frank writes about how our planet relates to the billions of other planets that are suitable for intelligent life, and why climate change is a problem that crosses the universe. It's a call to understand our world in context, and to understand the challenge facing our civilization... if we want that civilization to continue for a long time.
