Two atoms of hydrogen bound together with one atom of oxygen, more commonly known as water. This is one marvelous molecule and it can be found in more places than you might think. As far as we know water is essential to life. The only life we know of is right here on Earth. Which begs the question, is there any life out there? This is a question that NASA is actively trying to answer. Because we believe water is so important, the mission is "follow the water". Let the Sky Theater take you on an adventure through space and time to discover where we have found water beyond our planet.
