Deadly ImpactDVD - 2003
Asteriods and comets streak through the skies by the millions, and tons of small meteorites strike the earth. Scientists believe the dinosaurs died 65 million years ago as a result of a massive cosmic collision. Join Eugene and Carolyn Shoemaker who 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?
