"Dr. Robert Rubin, of the NASA Ames Research Centre in Moffett Field, California and his collaborators used Spitzer's spectrometer to measure neon and sulphur abundances in 25 star-forming regions across the nearby spiral galaxy M33. For the first time, they found that the ratio of neon to sulphur in all of these areas is relatively constant at about 16. They note that this observational result is not surprising because it is consistent with current models for how these chemical elements are created in the cosmos."
