SCIENCE EDITION / BEYOND OUR SOLAR SYSTEM Astronomers have discovered more than 5,000 planets in star systems outside of our solar system. Some of these extrasolar or exoplanets may even have the potential to develop and support life. Host Rick Pantaleo talks with guests from Cornell University’s Carl Sagan Institute and Penn State University’s Center for Exoplanets and Habitable Worlds to talk about the search for alien planets, especially those that may support life.
