Another exoplanet with no atmosphere

The James Webb Space Telescope has failed, for the second time, to find a thick atmosphere on an exoplanet in the TRAPPIST-1 system, a planetary system that could be hospitable to life. Like its neighbour TRAPPIST-1 b, the planet TRAPPIST-1 c probably never had many ingredients for habitability. There is still a chance that some of the five other TRAPPIST-1 planets might have atmospheres containing geologically and biologically interesting compounds.
