CHEOPS

The most stable source of light

The most stable source of light

To test the accuracy and stability of the CHEOPS photometer, a light source with a variability of less than the 20 ppm is required for the satellite. Since this type of source does not exist on the market, a team of engineers and technicians of the NCCR PlanetS and the University of Geneva has developed […]

Hot and stormy at high altitudes

Studying the atmosphere of an exoplanet, astronomers of the NCCR PlanetS derived a temperature profile with unprecedented precision. Their results are based on data collected with a relatively small ground-based telescope. This opens completely new perspectives for the characterization of remote exoplanetary atmospheres. High up in the atmosphere of the exoplanet named HD 189733b it […]

Test chamber for CHEOPS is installed

An outstanding vacuum chamber in a brand new laboratory is now waiting for the space telescope CHEOPS at the Center for Space and Habitability (CSH) of the University of Berne. Space experts will put the completely assembled flight instrument in the chamber and calibrate it therein under space conditions. At five and a half tones, […]

The CHaracterizing ExOPlanet Satellite (CHEOPS) has been selected in 2012 as the first S-class mission in ESA’s Science Programme. It is the first mission dedicated to search for planetary transits by means of ultrahigh precision photometry on bright stars already known to host planets. CHEOPS is a joint ESA-Switzerland mission. Watch a short video describing CHEOPS […]
