Astronomers sometimes find conflicting data when trying to answer a question. This is a normal part of the scientific process, and it simply means that more data is needed to prove or disprove the theory they are trying to test. One prominent example of conflicting data in recent exoplanet research was that of planet GJ 1132 b, which either had or didnt have an atmosphere, depending on which data set was being used. A new paper from researchers using more observational time on the James Webb Space Telescope (JWST) can now definitively say that, most likely, GJ 1132 b doesnt have an atmosphere - and that finding has wider implications for exoplanet research more generally.
