    Astrobiologists at NASA Ames Research Center funded by the NASA Astrobiology Institute have recently published a study on the analysis of Polycyclic Aromatic Hydrocarbons, or PAH’s, in the Iris Nebula. Their analyses of individual PAH spectra have allowed them to see how different types of PAH’s map to different areas of the nebula, and also how PAH behavior changes with respect to changes in the local environment.
