The search for extraterrestrial intelligence

Could there be life beyond Earth? Microbial life existing elsewhere in the Universe seems likely, but what about an intelligent civilisation? How are scientists searching for them, and what would it mean for planet Earth if we made contact with an alien species? In this episode, the SETI Institute’s Franck Marchis talks astrobiology, exoplanets and what he really thinks about UFOs. Hosted on Acast. See acast.com/privacy for more information.
