Approached by Die Zeit to create a visualization that displayed the latest discoveries from Kepler. 20 plus years ago, astronomers thought that planets had only formed in our solar system. Today we know this to be completely untrue and there are billions of planets in the Milky Way of all types. In fact there have been over 1000 exoplanets identified.
As of 4 November 2013, the Kepler mission space telescope has detected 3,568 candidate planets, of which about 11% may be false positives. There are at least 100 billion planets in the Milky Way, with at least one planet on average per star. The most recent planet found with a potential for holding life is Kepler-186-f.
