JWST Detects Highly Reflective Clouds on Exoplanet TOI-561 b

The James Webb Space Telescope (JWST) has observed highly reflective clouds, possibly composed of silicates, on the scorching lava exoplanet TOI-561 b, located 280 light-years away. These clouds reflect approximately 75% of the incoming starlight, which helps moderate the extreme temperatures. This discovery suggests a continually replenished atmosphere, potentially originating from a molten rock ocean on the planet.
