Our guest is Jaime Green, a science writer, essayist, editor, and teacher; she's also the series editor of The Best American Science and Nature Writing. She joins us to discuss her new book, "The Possibility of Life," which looks at how we as human beings imagine extraterrestrial life -- both in science and in science fiction. As was noted of this work by a critic writing for BookRiot: "A thought-provoking and entertaining read about not just the cosmos, but humanity."
