Temperate Rocky Exoplanets: First Results from the JWST and Future Perspectives

The investigation of atmospheres and surfaces of temperate rocky planets has, until recently, been confined to bodies within our own solar system (e.g., Earth, Mars, Venus). Over the past 2.5 years, however, the James Webb Space Telescope (JWST) has markedly advanced this field by delivering unprecedented data on nearby rocky exoplanets.

After a review of the first results obtained by JWST on rocky planets through transmission and emission observations, I will focus more specifically on two particularly promising systems: TRAPPIST-1 and LHS 1140b, which currently represent our two best opportunities for studying temperate rocky planets.

Finally, I will discuss medium- and long-term perspectives to deepen our understanding of their atmospheres and, ultimately, assess their potential habitability.
