One of two maps showing the distribution of carbon monoxide molecules in our Milky Way galaxy. This map is coded for intensity, from white (highest concentration of carbon monoxide), through yellow and red to blue (lowest concentration). The galactic centre is in the middle of the map. The two maps were made at a wavelength of 2.6mm with twin 1.2-metre radio telescopes, one in New York City, the other in Chile. (See R800/119 for the second map).
