What Is Life?

A dialogue with philosopher and director of the Center for the Study of Origins Carol Cleland, mineralogist and astrobiologist Robert Hazen, and ICE@Dartmouth Director Marcelo Gleiser


“What is life?” Surprisingly, there is no accepted definition. Life is one of those things that is easier to identify than to define. On Earth, living creatures have been found in the most exotic and forbidding environments, from under the Arctic ice sheet to the dark depths of oceans. What about in other worlds? Can we know if we found alien life if we don’t know what we are looking for? Join philosopher and director of the Center for the Study of Origins Carol Cleland, from the University of Colorado at Boulder and SETI Institute Affiliate, and mineralogist and astrobiologist Robert Hazen, from the Carnegie Institution and NASA Astrobiology Institute, in conversation with ICE@Dartmouth director, physicist Marcelo Gleiser, for a fascinating discussion of life known and unknown, here and, maybe, elsewhere in the cosmos.
