JWST suggests fewer habitable planets in the universe.

The James Webb Space Telescope has failed to find a thick atmosphere on the exoplanet TRAPPIST-1 c, suggesting that it lacks the ingredients for habitability. This is the second time the telescope has looked for an atmosphere in the TRAPPIST-1 system and failed to find one, reducing the number of potentially habitable planets. However, there is still hope for the other five planets in the system, as some may have thick atmospheres containing geologically and biologically interesting compounds.
