DMS and DMDS Hints in K2-18 b’s Atmosphere from JWST MIRI Data

Recent research paper published by the American Astronomical Society – New Constraints on DMS and DMDS in the Atmosphere of K2-18 b from JWST MIRI – digs into the atmosphere of K2-18 b, which is the exoplanet people have been calling a “Hycean World,” meaning it might have a hydrogen-rich atmosphere and liquid water oceans. This study is based on data from JWST’s MIRI (Mid-Infrared Instrument), and it’s the first time we’ve gotten a mid-infrared transmission spectrum of a habitable-zone exoplanet like this.
