Infrared eye on Titan
NASA’s Cassini spacecraft is still springing surprises about the Saturnian system, in particular the system’s largest moon, Titan. Cassini’s Visual and Infrared Mapping Spectrometer (VIMS) instrument gathered 13 years’ worth of infrared data of the 'Earth-like' satellite from which these infrared maps were formed.
Looking at Titan in the visible light wavelength doesn’t reveal much, as the surface of the moon is blocked by an orange, hazy atmosphere. The infrared observations provide a window to the surface, revealing its complex geology.
