Rémy Indebetouw, Geneviève de Messières, and the SAGE team look into the Large Magellanic Cloud to explore 30 Doradus, the closest super star cluster. They are using infrared spectral maps from the Spitzer Space Telescope, since features in the spectra can probe the different phases of the interstellar medium.
Bottom: zoom in on three details from the IRS spectral maps of 30 Doradus. Blue = sulfur emission (10.5 microns); green = PAH emission (11.3 microns); red = molecular hydrogen emission (12.4 microns).
