Part 4/8:
A groundbreaking revelation came recently when researchers detected particularly high concentrations of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in K218B’s atmosphere. These gases are currently tied to biological processes on Earth, primarily generated by marine phytoplankton. The significance of these findings lies in the fact that no non-biological mechanisms are known to produce such compounds, suggesting the presence of life or at least biological processes.
