This system of seven rocky worlds - all of them with the potential for water on their surface - is an exciting discovery in the search for life on other worlds. 6. The first extra-solar planet detected around a star similar to the Sun was 51 Peg. It has to be a comfortable distance away from a star (Habitable Zone) The stars around it have to be 'stable'. Kepler looked for planets in a wide range of sizes and orbits. Liquid water is essential to all life on Earth, and so the definition of a habitable zone is based on the hypothesis that extraterrestrial life would share this requirement. Nearly all of the oxygen in the earth's atmosphere was originally produced by photosynthesis in the leaves of trees that covered the continents 3.5 billion years ago. Visual Activity Exploring the Habitable Zone around a Central Star. Exoplanet Exploration Program NASA's science, technology and mission management office for the exploration of exoplanets. Around a star, there is a shell-shaped region of space, called the Habitable Zone (HZ), where a planet can maintain liquid water on the surface. Overview.
