Story summary

Research on TOI-270 b indicates it may possess a water-rich atmosphere, challenging earlier assumptions.
The JWST transmission spectrum shows potential evidence for water, supporting a steam atmosphere model.
TOI-1203 d is confirmed as a sub-Neptune with a mass of 7.39 M?, alongside the discovery of super-Earth TOI-1203 b at 3.51 M?.
Stability analysis reveals configurations in the TOI-1203 system can remain stable over billion-year timescales.
These findings enhance our understanding of atmospheric retention and evolution in exoplanets.
