Cosmic Hazards — How Dangerous is Your Cosmic Neighborhood?

Over the last few decades humans have not only learned that we are traveling through space on our own very special spacecraft called Planet Earth but that the journey we take around the Sun each year is actually a very hazardous journey. In some ways we are playing Russian roulette with a random set of rock and metal bullets that were first fired at our small six sextillion-ton planet millions of years ago.
