Story summary

The study led by Professor Eliza Kempton suggests that some sub-Neptunes may possess solid surfaces due to atmospheric pressure and temperature.
NASA's Kepler spacecraft, launched in 2009, initiated a wave of exoplanet discoveries, revealing the prevalence of mini-Neptunes.
The findings have implications for JWST observations to deepen understanding of these planets and their evolution.
The work underscores the complexity of planetary formation beyond our Solar System.
