Web users around the globe will be able to help professional astronomers in their search for Earth-like planets thanks to a new online citizen science project called Planet Hunters.

Planet Hunters, which is the latest in the Zooniverse citizen science project collection, will ask users to help analyze data taken by NASA’s Kepler mission. The space telescope has been searching for planets beyond our own solar system — called exoplanets — since its launch in March 2009.

When users log on to the Planet Hunters website, they’ll be asked to answer a series of simple questions about one of the stars’ light curves — a graph displaying the amount of light emitted by the star over time — to help the Yale astronomers determine whether it displays a repetitive dimming of light, identifying it as an exoplanet candidate.
