It has been speculated that near half of the stars in our galaxy have a planet orbiting them. NASA’s Kepler Mission was tasked to search for those planets. Kepler was able to see if a planet was present if a dip in the star’s brightness occurred.
However, NASA needs your help. There is so much data, it is hard for just one astronomer to go through. That is where you can help! Visit the Exoplanet Explorers page for your next steps.
