Enaiposha defies planetary labels with a hazy, Venus-like atmosphere
Using JWST data, Enaiposha (GJ 1214 b)—a planet about 47 light-years away—emerges as a hazy, Venus-like world that defies its sub-Neptune classification. Its thick, cloud-laden atmosphere may host molecules like water vapor, carbon dioxide and metals, suggesting a metal-rich, hot atmosphere unlike anything in our solar system; the hazes make atmospheric analysis difficult but provide a new lens on thick-atmosphere evolution. Although not habitable, Enaiposha could help scientists reinterpret planetary types and refine models for other exoplanets.
