    NASA's Kepler mission is designed to discover planets. It looks for the dimming in a star that occurs as a passing planet blocks a tiny fraction of its star's light. The Kepler team has released new results that suggest that at least one system it examined contains several planets in the habitable zone, the area where water might exist. Water is a necessity for an environment that can sustain life as we know it.
