TRAPPIST-1: November 2019

Near-term studies of Venus-like atmospheres with JWST promise to advance our knowledge of terrestrial planet evolution.

The TRAPPIST-1 system, consisting of an ultra-cool host star having seven known Earth-size planets will be a prime target for atmospheric characterization with JWST.

Mass-radius relationships for water-rich terrestrial planets are usually calculated assuming most water is present in condensed (either liquid or solid) form.
