Webb Telescope Unveils Extreme Weather on Nearby Brown Dwarfs

New observations provide a detailed 3D look at the atmospheric conditions of two brown dwarfs six light-years from Earth.

The study used the James Webb Space Telescope to observe the closest brown dwarfs to Earth, located six light-years away.
Researchers created the most detailed weather maps to date, showing temperatures around 1,700°F and clouds of silicate particles.
The brown dwarfs' atmospheres are dominated by hydrogen and helium, with trace amounts of water vapor, methane, and carbon monoxide.
Fast rotations of the brown dwarfs, with periods of five and seven hours, drive their dynamic weather patterns.
These findings could help study weather on potentially habitable exoplanets in the future.
