Titan, close and in false colour
This image shows Titan in ultraviolet and infrared wavelengths, taken by the NASA/ESA/ASI Cassini-Huygens spacecraft on 26 October 2004, during the close fly-by.
This image is constructed from four images acquired through different colour filters. Red and green colours represent infrared wavelengths and show areas where atmospheric methane absorbs light.
These colours reveal a brighter (redder) northern hemisphere. Blue represents ultraviolet wavelengths and shows the high atmosphere and detached hazes.
Titan has a gigantic atmosphere, extending hundreds of kilometres above the surface. The sharp variations in brightness on Titan’s surface (and clouds near the south pole) are apparent at infrared wavelengths.
