Kepler Mission and Exoplanet Discovery

NASA's Kepler mission provides a comprehensive data set to help researchers discover Earth-sized planets in our galaxy. The Planet Candidate Catalog, using four years of Kepler observations, includes 219 new planet candidates, with ten in habitable zones. Kepler data reveals two size classes of small planets: Earth/Super-Earth and mini-Neptune. Over 4,000 planet candidates have been identified, with 2,335 confirmed. Kepler's search continues, aiming to reveal planet demographics and aid the search for life.
