Every year, millions of asteroids and comets or ''stray bullets'' streak through the skies, and tons of small meteorites strike our planet! 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 extraordinary geologist Eugene Shoemaker and his wife Carolyn who have remapped the heavens with their discoveries of more than 30 comets and hundreds of asteroids.





First and foremost, Asteroids: Deadly Impact is a story about how the world could end. Underlying its premise we find the pillars of asteroidal impact theory, the scientists Eugene and Carolyn Shoemaker. The Shoemakers will go down in the books as codiscoverers of Comet Shoemaker-Levy 9, but their story here is of meteorological sleuthing and, quite frankly, the sheer horror of unpredictable planetary collision. An asteroid slightly more than a mile wide would destroy life on Earth in an unforgiving blast of heat and dust. The funny thing is, there wouldn't be much evidence of this other than a crater (to be mistaken later as volcanic) and a strange mineral called coesite. How do they know? The Shoemakers would say the answer is in the fragments long forgotten. In Asteroids, we follow them from airy theory to cold, hard evidence of asteroids and their deadly havoc on Earth.
