They are celestial travelers which have forever filled us with fear and wonder. Lurking in the furthest reaches of our solar system, comets sometimes brush the Earth as they orbit our Sun. But could something so potentially destructive hold the key to life? Are the building blocks of carbon-based life forms frozen inside? Might they contain information about the creation of our solar system?
At the conclusion of two spectacular NASA missions, COMETS: PROPHETS OF DOOM examines the scientific and historical record of comets, including man's reaction to them. Did a comet lead the Wise Men to Bethlehem? Did they foretell the death of kings, the destruction of civilizations? How did Halley's Comet provide Isaac Newton with the clues for his theories of gravity? Finally, what are these cosmic snowballs made of, and can we protect ourselves if one takes a collision course toward the earth?
