The chemistry of the Universe

When scrutinising selected objects ISO could detect the emission or absorption of infrared rays at particular wavelengths, or "lines" in a spectrum, revealing the presence of identifiable atoms, molecules and solids. The Short Wavelength Spectrometer and the Long Wavelength Spectrometer, along with the photometer ISOPHOT and the camera ISOCAM, provided detailed chemical diagnoses of celestial objects.
