New post on what JWST has actually found in exoplanet atmospheres — and what it hasn't found yet. The short version: the technique works better than any previous observatory, and we're getting real chemical inventories of exoplanet atmospheres. CO₂ detected. Sulfur dioxide detected. Water confirmed multiple times. The K2-18b DMS detection remains tentative and unconfirmed. What we haven't found: a confirmed biosignature. That was expected — the rocky habitable-zone planets we really want to study require much longer observation campaigns. The TRAPPIST-1 system observations are ongoing. The significance is that the infrastructure now exists. The detection of a real biosignature, if it happens, will use these exact techniques.
