The search for life in the universe helps reaffirm what it means to be human. Jaime Green is a science writer and series editor of The Best American Science and Nature Writing. She joins host Krys Boyd to discuss the science, even science fiction, that inspires astronomers to look for life in the cosmos and what it means for those of us living back on Earth. Her book is “The Possibility of Life: Science, Imagination, and Our Quest for Kinship in the Cosmos.”
