Life zones around three stars, artwork
Life zones around three stars, artwork. The star types are, from top: hotter stars, sunlike stars, and cooler stars. The colours show the habitable zones (green), the zones that are too hot (red) and the zones that are too cold (blue). Earth, Venus and Mars are shown orbiting the sunlike star in the middle diagram. In 2009, NASA launched its Kepler Mission to discover Earth-like planets orbiting other stars. The mission is named in honour of German astronomer Johannes Kepler.
