Ancient Earth, Alien Earths
The implications of studying "Ancient Earth" provides a stepping stone in order to study life in the universe. This NASA panel consists of Chris House, Phoebe Cohen, Tim Lyons, Dawn Summer, and Shawn Domagal-Goldman. Dr. Domagal-Goldman is one of the NASA collaborators for this project. This panel discusses a wide range of topics focusing on Ancient Earth, the beginning of life, and studying life elsewhere in the universe (and how we can use our own planet's past to study exoplanets).
