Story summary

Researchers at McGill University mapped the atmosphere of SIMP 0136, a free-floating brown dwarf 20 light-years away in Pisces.
Using the James Webb Space Telescope, they observed weather patterns and identified at least three atmospheric layers.
The study found north-south asymmetry, indicating chaotic weather similar to Jupiter.
The findings advance understanding of brown-dwarf atmospheres and support future exoplanet weather studies.
