(PhysOrg.com) -- University of Pittsburgh planet hunters based at the Allegheny Observatory were one of nine teams around the world that tracked a planet 190 light-years from Earth making its rare 12-hour passage in front of its star. The project resulted in the first ground-based observation of the entire unusually drawn out transit and established a practical technique for recording the movement of other exoplanets, or planets outside of Earth`s solar system, the teams reported in The Astrophysical Journal.
