Sub-Neptune exoplanets are intriguing celestial bodies that may exhibit extreme atmospheric conditions. Researchers believe that the atmospheres of these planets could be so dense and crushing that they can vaporize rock.
This vaporization process could lead to the formation of clouds composed of vaporized rock, which would significantly impact the thermal dynamics of the planet's surface.
As a result, the surface of these exoplanets may be dominated by oceans of molten magma, creating a hostile environment unlike anything found on Earth.
