JWST Detects Reflective Atmosphere on Exoplanet TOI-561b

James Webb Space Telescope observations, detailed in a new preprint, indicate a surprisingly reflective atmosphere on the ultra-short period rocky exoplanet TOI-561b. This finding challenges expectations for such planets, which are typically thought to lack substantial gaseous envelopes due to intense stellar radiation. The preliminary research offers new insights into exoplanetary atmospheric dynamics.
