## Researchers Develop a Way to Check the Weather on a Exoplanet Using data from the James Webb Space Telescope (JWST), an international team of researchers decoded the weather on a distant exoplanet. The target in question was SIMP J0136+09 (or SIMP 0136), a well-studied brown dwarf located about 20 light-years from Earth in the constellation Pisces. The method they used employs Principal Component Analysis (PCA), a statistical technique that simplifies complex data by keeping the variables that change together while discarding the rest. The results showed that weather on SIMP 0136 is driven…
