(Phys.org)—Studying planets around other stars will be the focus of the new small Science Programme mission, Cheops, ESA announced today. Its launch is expected in 2017. Cheops – for CHaracterising ExOPlanets Satellite – will target nearby, bright stars already known to have planets orbiting around them. Through high-precision monitoring of the star's brightness, scientists will search for the telltale signs of a 'transit' as a planet passes briefly across its face.
