In a groundbreaking discovery, researchers using NASA’s James Webb Space Telescope (JWST) have detected the first evidence of an atmosphere around the ultra-hot exoplanet 55 Cancri e. Initially believed to be too hot and close to its star to support an atmosphere, new data from JWST has revealed otherwise. By analyzing the planet’s thermal emissions and chemical composition, scientists have uncovered the presence of a carbon-rich ‘secondary atmosphere’ that is replenished by the planet’s interior.
