Plume Composition : Comet 67P vs Enceladus

Gases common to plumes of comet 67P & Saturn's moon Enceladus. Sources of info can be seen by clicking on the names & are different for both bodies. 

For multiple sources to same info, just search for object name & ingredient name. For example, search for "comet 67P oxygen" or "Enceladus argon". Some links have already been incorporated into the table, click number next to name to see it.

6 most critical elements needed for life are known collectively by the acronym CHNOPS : carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. All 6 are present on both comet 67P & Enceladus moon.
