Known Universe: Cosmic Collisions – National Geographic (2010)

Known Universe: Cosmic Collisions - National Geographic Documentary

Right now, massive meteors and asteroids are orbiting dangerously close to Earth. Some may even be poised to hit us in the foreseeable future! Where are they?

What type of damage will they cause? What can we do stop a caroming asteroid thats headed toward us, or prevent future Near Earth Objects from lining us up in their sites.

They have left deep scars all over the face of our planet and are responsible for one of the biggest extinctions in history. Scientists believe that its not a question of if theyll strike again, but when.

Known Universe: Cosmic Collisions - Could an asteroid impact with Earth wipe out the human race? This National Geographic documentary film explores what is being done to prevent such an Armageddon by heading to the first line of asteroid defense: the Lunar and Planetary Laboratory in Arizona.

Here we see the technologies used to monitor the skies for near-Earth objects, including a football stadium-sized rock that will pass close to Earth on Friday the 13th, April 2029. Scientists predict it may be so close that gravity could cause a catastrophic collision.
