JWST ruled out thick carbon dioxide atmosphere on potential Venus analog TRAPPIST-1 c

Star system: TRAPPIST-1 | Distance from the Sun: 40.7 light years

The exoplanet was thought to be similar to Venus. However new observations with James Webb Space telescope ruled out thick atmosphere with dominant carbon dioxide.
