Using the CHEOPS space telescope, researchers from the University of Bern have carried out a detailed study of the exoplanet, dubbed WASP-189b. The planet orbits the star HD 133112, which is one of the hottest stars known to have a planetary system. Ms Lendl said: “Based on the observations using CHEOPS, we estimate the temperature of WASP-189b to be 3,200 degrees Celsius. Instead, the CHEOPS telescope uses high precise brightness measurements to detect planets. Instead, most of the starlight gets absorbed by the planet, heating it up and making it shine."
