Composite image of Saturn
Légende
This false colour composite image of Saturn is constructed from data collected in the near-infrared wavelengths of light: blue is used to indicate sunlight reflected at a wavelength of 2 microns, green to indicate sunlight reflected at 3 microns and red to indicate thermal emission at 5 microns. The heat emission from the interior of Saturn is only seen at 5 microns wavelength in the spectrometer data, and thus appears red.
