Some 65 million years ago, dinosaurs were wiped off the face of the Earth - in what many believe was the aftermath of a massive cosmic collision. Could something like this happen again? Scientists believe that the impact of an asteroid only a mile wide would be globally catastrophic. Join renowned geologist Eugene Shoemaker and his wife, Carolyn, who together have remapped the heavens with their discoveries of more than 30 comets and hundreds of asteroids. Now that we know what's out there, how can we defend ourselves? Special Feature: Interactive Quiz Standard Version / Not Rated / 60 Minutes / Color
