Searching for extraterrestrial life has created a new scientist: the astrobiologist. Curator of Astrobiology at the Denver Museum of Nature & Science David Grinspoon, NASA’s Shawn Domagal-Goldman and UK astrobiologist and FameLabber Lewis Dartnell explore some mind-blowing discoveries and the future of hunting for life beyond Earth.
