General Information：
Science Documentary hosted by Eric Meyers, published by National Geographic broadcasted as part of NG Earth Investigated series in 2007- English narration

Information
A powerful series that gives real answers to some of the most provocative questions facing mankind today. Using carefully-researched CGI reconstructions and expert contributions, this program examines major events and phenomena.
Planet Science goes on journey through the Solar System and beyond, examining some of the most extreme characteristics of our planetary neighbours.
Comets, distant travellers from the outer parts of our solar system, have long been shrouded in mystery. Now, through Earth-based observations and space probes, their origins and nature are unveiled.
Scientists are only now starting to unravel the secrets of comets. Often referred to as dirty snowballs, they contain ice and elements from the very start of the universe. Some theorize that a comet, crashing into our planet, brought with it the organic material that started life on Earth. Spacecraft continues to offer new information on their makeup, from bringing back samples from a comet's tail to direct contact when a NASA-launched craft slammed into the comet Tempel-1.
Produced by Pioneer Productions for National Geographic Channel
