إكتشاف مكون Dimethyl Sulfide (DMS) على كوكب K2-18B و الذي يتم إنتاجه فقط من طرف الكائنات العضوية الحية مثل الPhytoplanktons
The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b. These initial Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life. The bulk of the DMS in Earth’s atmosphere is emitted from phytoplankton in marine environments.
