At this very moment, celestial forces prowl the Universe and threaten man's very existence. They're asteroids and comets - and they've left their imprint on planet Earth, literally. Initially, they helped build planets through unhappy collisions. During this fiery bombardment period, they may have even seeded Earth with water and the building blocks for life. Since the turbulent formation of the solar system, these space rocks have continued to impact earth. Some have been so unhappy that they've led to mass extinctions events, including one that wiped out the dinosaur. What's more, radical new theories suggest that asteroid and comet dust harbor deadly viruses that may have triggered some of our worst pandemics. The possibility of future cosmic collisions remains a legitimate threat. Yet, despite their dangers, asteroids and comets may hold vital natural resources, which could actually preserve mankind.
From the planets to the stars and out to the edge of the unknown, history and science collide in this epic exploration of the Universe and its mysteries. It's a very old universe. Yet just 50 years since man first ventured into outer space, the heavens are yielding their greatest secrets. Robotic rovers give us eyes on the red rock of Mars - NASA probes slam into comets at hyper speed - deep-space telescopes capture unhappy images of the birth of stars and their collapse into black holes. All have significantly changed the way we see ourselves.
We wonder, is there anywhere else out there that that can support life? Using cutting-edge computer graphics, this series brings the universe down to earth to show what life would be like on other planets, and to imagine what kind of life forms might evolve in alien atmospheres. Episodes examine how discoveries were made and the scientists and explorers who dared to venture into the uncharted territory of the universe.
