Asteroid: Doomsday or Payday?

Season 40 Episode 24 | 53m 49s | CC

The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range.

In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves.
