- Assertion
- Four new JWST NIRSpec transit observations robustly detect CH4 and CO2 and indicate a water-rich planet. The spectrum contains only marginal DMS signals, below about 2 sigma without a strong haze. Photochemical models show DMS may form without life in massive hydrogen-rich atmospheres of high metallicity.
