NASA’s James Webb Space Telescope Detects Possible Atmosphere on Hot Rocky Exoplanet 55 Cancri e

Researchers using NASA’s James Webb Space Telescope have detected potential evidence of atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet located 41 light-years from Earth. This discovery marks the best evidence to date for the existence of a rocky planet atmosphere outside our solar system. The findings, published in Nature, suggest that Webb is pushing the boundaries of exoplanet characterization to include rocky planets.
