Aliens

Description

At the bottom of the Pacific Ocean, a submarine observes extraordinary life forms that thrive without heat or light. Organisms like these have raised expectations about Europa, one of Jupiter's moons. Patterns in Europa's surface ice suggest that, far below, aquatic life is possible. This program also assesses another compelling clue in the search for extraterrestrial biology: if bacteria breathing toxic gas can live in a desolate Mexican cave, could similar creatures also survive in newly-discovered caves on Mars? Despite these tantalizing scenarios, the film culminates in a celebration of life on Earth-in all its beauty, diversity, and sophistication, still the greatest wonder of the solar system.
