Here’s a look back at some of the space telescope’s discoveries.
The newly discovered "mega-Earth" Kepler-10c appears in the foreground of this artist's illustration. Its sibling in red, the lava world Kepler-10b, is in the background. Both orbit a sunlike star. Kepler-10c has a diameter of about 18,000 miles, 2.3 times as large as Earth, and weighs 17 times as much. Comprised of all solids, it may possess a thin atmosphere shown here as wispy clouds.David A. Aguilar/Harvard-Smithsonian Center for Astrophysics
