Cosmic Collisions is a Discovery Channel documentary series that takes you up into the vast stretches of outer space to examine the constant movement of cosmic objects, the likelihood of a collision between them, and the projected aftermath of such collisions. Asteroids, comets, planets, and more are constantly hurtling through outer space. Should the paths of two objects intersect, the impact could cause a spectacular amount of damage. In this series, scientists discuss the probability of cosmic objects colliding with Earth, and the measures scientists have taken to prevent such an event. We know asteroids have been colliding with Earth since the dawn of time, as Earth's many craters indicate. Watch as scientists examine these craters to reveal clues about the nature of the impacts and the devastation they caused on the planet. Cosmic Collisions is an informative and educational series about the dangers in the skies above us and the methods we employ to protect our planet.
