We now know there are more planets than stars in the galaxy. Many of them are very different from ours. How would we know if any of them had life? Shawn Domagal-Goldman, astrobiologist at NASA’s Goddard Space Flight Center, discusses these strange and wondrous worlds beyond our Sun. He and others at NASA are working on concepts for future space telescopes that could actually find exoplanets that resemble Earth, and detect chemicals that only life could produce. And what would such a discovery mean? Find out in this episode.
