An article published in the journal “Nature Communications” provides an explanation for the presence of oxygen molecules on the comet 67P/Churyumov-Gerasimenko. Konstantinos Giapis, a chemical engineer at Caltech, conducted this research after noting that the chemical reactions that took place on the comet’s surface were similar to those he had been generating for years. The most likely hypothesis initially offered was that it had “survived” since the solar system’s formation but perhaps the correct explanation has now been found.
