Here’s How the Universe Can Make Dimethyl Sulfide in Interstellar Space. No Life Required.
Dimethyl Sulfide (DMS) has been in the news again, this time for its discovery in the atmosphere of the hycean world K2-18b as a potential biosignature. In an interesting twist, astronomers have also detected DMS in comets and in giant molecular clouds. It shows there must be an abiotic way for this chemical to be produced. A team of researchers have studied DMS and developed different gas phase reactions that could produce this chemical and explain its presence that doesn’t require life.
