The above image is a 3-colour composite of the molecular gas within our Galaxy, showing a tiny part of “The Three-mm Ultimate Mopra Milky Way Survey” (ThrUMMS) . Red, green, and blue correspond to the molecules; 12 CO, 13 CO, and C 18 O, respectively (Barnes, Muller et al. 2015). Green or blue are cooler and more opaque regions, while the red is warmer and more translucent. The full-scale map produced by this survey is 5.5 m long when printed a typical printing resolution of 75 dpi.
