Are we alone in the universe?

So far, the only intelligent life we know of is right here on Earth — us! But could there be life on other planets just waiting to be discovered? In this episode, Tai goes deep in the cosmos to explore how scientists are searching for signs of life beyond our little blue dot, and what their work can tell us about our place in the universe. In this episode Tai talks to: - Nathalie Cabrol, astrobiologist and director of research at the SETI Institute - Jacob Haqq-Misra, senior research investigator at the Blue Marble Space Institute of Science - Heidi White, astrophysicist at the University of Toronto
