Rosetta’s Spectrometer Detects Noble Gas Argon at 67P/Churyumov-Gerasimenko

The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) mass spectrometer aboard ESA’s Rosetta spacecraft has detected the noble gas argon, along with other gases, in the coma of 67P/Churyumov-Gerasimenko. The so-called noble gases rarely react chemically with other elements to form molecules, mostly remaining in a stable atomic state, representative of the environment [...] —> Read More
