The first sequence of this animation shows the Kepler spacecraft as it leaves the Earth to go into orbit around the Sun. The spacecraft soon turns to point to the 100,000 stars in our galaxy that it will monitor for four years looking for planetary transits.
The second sequence shows how a planet in a distant system periodically blocks some of the light bound for the Kepler spacecraft, signaling the presence of a planet.
The animation was created by artist Donald Grahame.
