Webb Telescope captures turbulent weather on distant exoplanet.

The James Webb Space Telescope has detected silicate cloud features in the atmosphere of exoplanet VHS 1256 b, which is about 40 light-years away and orbits two stars. The planet's atmosphere is constantly rising, mixing, and moving during its 22-hour day, resulting in dramatic brightness changes. The team also detected water, methane, carbon monoxide, and carbon dioxide, making it the largest number of molecules ever identified on a planet outside our solar system. The researchers used two spectrographs aboard Webb to observe the planet's near- to mid-infrared light emitted and identified silicate clouds, water, methane, and carbon monoxide.
