In the lab, scientists have pinpointed a specific wavelength of infrared light absorbed when molecules of carbon monoxide and nitrogen join together and vibrate in unison. Individually, carbon monoxide and nitrogen ices each absorb their own distinct wavelengths, but the tandem vibration of their mixture absorbs at an additional, distinct wavelength. Now, astronomers using the 8-m Gemini South Telescope in Chile have recorded this same unique signature...
