Titan in three different wavelenghts: the strange Titan (3)

Caption NASA originale:"This false-color composite was created with images taken during the Cassini spacecraft's closest flyby of Titan on April 16, 2005.
It was created by combining 2 infrared images (taken at 938 and 889 nnmts) with a visible light image (taken at 420 nnmts). Green represents areas where Cassini is able to see down to the surface. Red represents areas high in Titan's stratosphere where atmospheric methane is absorbing sunlight. Blue along the moon's outer edge represents visible violet wavelengths at which the upper atmosphere and detached hazes are better seen.

A similar false-color image showing the opposite hemisphere of Titan was created from images taken during Cassini's first close flyby of the smoggy moon in October 2004 (see PIA06139). At that time, clouds could be seen near Titan's South Pole, but in these more recent observations no clouds are seen. North on Titan is up and tilted 30° to the right".
