Dr. Stephen Kane (San Francisco State University) Over 1500 new planetary systems have been discovered, many of which include planets quite different from those in our own Solar System. A key step towards finding “Earth 2.0” will be to identify rocky planets that occupy the “Habitable Zone” of their stars. Dr. Kane describes what the idea of a Habitable Zone means and shows examples of planets that lie in their star’s Habitable Zone (even if the star is not like our Sun.)
