Finding Life Beyond Earth: Are We Alone?
Take a spectacular trip to distant realms of our solar system to discover where secret forms of life may lie hidden. Combining the latest telescope images with dazzling animation, this program immerses audiences in the sights and sounds of alien worlds, while top astrobiologists explain how these places are changing how we think about the potential for life in our solar system. We used to think our neighboring planets and moons were fairly boring—mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than we ever imagined.
