JWST reveals metal-rich atmosphere on GJ 1214b.

Scientists have used the James Webb Space Telescope (JWST) to study the atmosphere of exoplanet GJ 1214b and found it to be reflective and metal-rich. The planet, which is about 40 light-years away from Earth, is a "super-Earth" with a radius about 2.7 times that of Earth. The findings suggest that GJ 1214b's atmosphere is unlike any other known exoplanet and could provide insights into the formation and evolution of planets.
