Challenging DMS as a Biosignature: New Evidence from Cometary and Interstellar Studies
Recent findings by a research team from the University of Bern reveal the presence of dimethyl sulfide (DMS) in comet 67P/Churyumov-Gerasimenko, challenging its role as a biosignature. Utilizing data from the Rosetta mission, researchers showed that DMS can form through abiotic processes. This discovery, coupled with DMS detection in the interstellar medium, stresses the need for careful evaluation of biosignatures in space.
