New JWST/MIRI phase curves of TRAPPIST-1 b and c. We directly constrain both dayside and nightside emission of temperate Earth-sized planets for the first time. The strong day–night contrast rules out thick atmospheres. www.exotic.uliege.be/cms/c_136702... www.nature.com/articles/s41...
First Thermal Mapping of Temperate Earth-sized Exoplanets
The James Webb Space Telescope has, for the first time, mapped the temperature distribution of the temperate, Earth-sized rocky exoplanets TRAPPIST-1 b and c, showing that they are likely devoid of th...
