Almost every star is now thought to form with a planetary system around it. But just how rare a phenomenon are habitable planets? In this podcast, Massachusetts Institute of Technology professor Linda Elkins-Tanton discusses what is currently known about planetary formation—and what is needed to encourage the development of life.

Dr. Elkins-Tanton’s talk, “A Hitchhiker’s Guide to Habitable Planets in Our Galaxy,” was recorded at the Museum on April 11, 2011.
