NASA’s Webb Spots Swirling, Gritty Clouds on Remote Planet



Weather report: Expect scattered, patchy clouds made up of silicates on planet VHS 1256 b.

Ever had sand hot whip across your face? That’s a soothing experience compared to the volatile conditions discovered high in the atmosphere of planet VHS 1256 b. Researchers using NASA’s James Webb Space Telescope proved that its clouds are made up of silicate particles, ranging from fine specks to small grains. Plus, its near-constant cloud cover is on the move! The team projects that the silicates swirling in these clouds periodically get too heavy and rain into the depths of the planet’s atmosphere. Webb’s observations also show clear signatures of water, methane and carbon monoxide, and provide evidence for carbon dioxide. This is only the beginning of the team’s research – many more findings are expected as they continue to dig in to Webb’s “downpour” of data.
