PARIS (ESA PR) — ESA’s exoplanet mission  Cheops has revealed a unique planetary system consisting of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star. The sizes and masses of the planets, however, don’t follow such an orderly pattern. This finding challenges current theories of planet formation.

Vaporised Metal Found in the Air of an Exoplanet

BERN, Switzerland (University of Bern PR) — An international team of researchers led by the National Centre of Competence in Research PlanetS of the University of Bern and the University of Geneva studied the atmosphere of the ultra-hot exoplanet WASP-121b. In it, they found a number of gaseous metals. The results are a next step in the search for potentially habitable worlds.

First Results from Cheops: ESA’s Exoplanet Observer Reveals Extreme Alien World

PARIS (ESA PR) — ESA’s new exoplanet mission, Cheops, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates Cheops’ unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.

Launched in December 2019, Cheops (the Characterising Exoplanet Satellite) is designed to observe nearby stars known to host planets. By ultra-precisely measuring changes in the levels of light coming from these systems as the planets orbit their stars, Cheops can initially characterise these planets — and, in turn, increase our understanding of how they form and evolve.

MADRID, 26 March 2020 (Airbus PR) – Airbus has received confirmation from ESA of a successful end to the In Orbit Commissioning (IOC) of CHEOPS after the IOC review yesterday. This critical phase was performed by Airbus in Spain with the support of the Instrument Team (University of Bern), Mission Operation Centre (INTA), Science Operation Centre (University of Geneva) and ESA.
