Greenlit: Are We Alone? Discovery Channel

Are We Alone? – Almost forty years after man first walked on the moon, this documentary takes a fresh look at one of science’s greatest mysteries. Are there life forms existing beyond Earth? Could the bizarre, hellish worlds of our solar system harbor or evolve alien biology? And does Earth itself provide a road map to answers for these age old questions.

It ventures to Earth’s strangest, most extreme regions to uncover clues to the universe’s evolution. From Death Valley, California, to the glaciers of Chile; from the harsh desert climates of Africa to the lush seascapes of the Caribbean, the world’s top astrobiologists and astrophysicists examine the geological record and the biological influence of life forms that created and continue to sustain life on Earth. Could this answer the profound question of whether life is possible in our own universe or beyond?

Geologically and biologically, Earth serves as a virtual science lab, providing many intriguing parallels to the development of life forms elsewhere, while answering many complex questions about how life adapts to and evolves in extremely harsh environments. The challenging conditions for the existence of life on our planet allows experts to posit theories of how alien life could exist or develop on other planets.

Gentry Lee, Chief Engineer for the Solar System Exploration Directorate at the Jet Propulsion Laboratory, narrates. He managed the tremendously successful NASA rover missions to Mars, which recently uncovered astonishing evidence of the existence of water, the key to life in the universe. Lee was also involved in the Viking and Galileo space missions. He also notably collaborated with Carl Sagan on the Emmy® and Peabody® award-winning series, Cosmos, and coauthored popular science fiction works with the esteemed, late Arthur C. Clarke.Channel: Discovery Channel
