The James Webb Space Telescope detected a hydrogen-rich atmosphere on the super-Earth exoplanet 55 Cancri e. This lava planet, located 41 light-years away, orbits its star closely, resulting in surface temperatures hot enough to melt rock. The atmosphere's composition suggests volcanic outgassing from its molten interior. Researchers observed variations in the atmosphere, possibly due to temporary clouds formed by escaping gases, offering insights into the planet's internal chemistry.
