๐ญ Webb Found a Planet Where Rock Clouds Form Every Morning and Vanish by Night
Using the James Webb Space Telescope, Johns Hopkins astronomers found that WASP-94A b โ a hot Jupiter orbiting just 5 million miles from its star โ has mornings choked with magnesium silicate clouds (mineral rock) that evaporate into clear skies each evening as the dayside heat takes over. It's the sharpest map yet of a rock cloud cycle on another world, confirming the planet is far more Jupiter-like than expected. The findings were published in May 2026. Would you want to watch a sunrise where the clouds are literally made of vaporized rock?
