Are we alone in the universe?

Astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie Cabrol takes us to the frontiers of the search for life. The odyssey begins with how life began on Earth in order to understand what’s necessary for life to exist elsewhere. What role did our Moon play? And could life on Mars, or another world, have seeded life on Earth?

Cabrol illuminates the likeliest places for life in our neighborhood, then seeks life beyond our Solar System, looking at the recent revolution in the night sky: the realization that there are more than 300 million exoplanets in the habitable zone of our galaxy. Cabrol shares the deepest insights and most provocative theories on if we may ever find an advanced alien civilization.
