Story summary

Researchers using the James Webb Space Telescope study SIMP-0136, a rogue planet 20 light-years from Earth, revealing extreme weather.
Temperatures near 1,500°C and auroras heat its stratosphere.
Observations show temperature variations under 5°C and magnetic forces drive complex atmospheric dynamics.
SIMP-0136 has cloud coverage of iron and silicate particles, and magnetic and thermodynamic processes dominate its weather, challenging L-T theories.
