A powerful space telescope, due for launch from Europe’s Spaceport in French Guiana on 17 December 2019, will give scientists a new insight into the nature of planets outside our Solar System.

Cheops, the 'Characterising Exoplanet Satellite', will study known exoplanets that are orbiting bright stars.
More than 4000 exoplanets have been discovered and Cheops will be targeting known planets between the size of Earth and Neptune, to find out more about their composition, internal structure and whether they might be able to support life.

Cheops' mission is a partnership between ESA and Switzerland with additional contributions from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the UK.

This film examines the nature of exoplanets, the challenge of exoplanet exploration and features the Cheops Science Operations Centre in Geneva, it includes interviews with Didier Queloz, Chair of the Cheops Science Team and 2019 Nobel Physics Laureate, University of Geneva; Willy Benz, Cheops Principal Investigator, University of Bern; and Matthias Beck, Cheops Ground Segment Manager, University of Geneva).
