Kepler Data Tutorial : What can you do?
The Kepler mission was designed to hunt for planets orbiting foreign stars. When a planet passes between the Kepler satellite and its home star, the brightness of the light from the star dips.
That isn’t the only reason for changes in brightness but officially, Kepler has to ignore those other reasons. Unofficially, Kepler has encouraged professional and amateur astronomers to search the Kepler data for other reasons for light curves.
As I mentioned last year, Kepler Telescope Data Release: The Power of Sharing Data, a group of amateurs discovered the first system with four (4) suns and at least one (1) planet.
The Kepler Data Tutorial introduces you to analysis of this data set.
