With its thick, distended atmosphere, Titan's orange globe shines softly,
encircled by a thin halo of purple light-scattering haze.
Images taken using blue, green and red spectral filters were used to
create this enhanced-color view; the color images were combined with an
ultraviolet view that makes the high-altitude, detached layer of haze
visible. The ultraviolet part of the composite image was given a purplish
hue to match the bluish-purple color of the upper atmospheric haze seen in
visible light.
Small particles that populate high hazes in Titan's atmosphere scatter
short wavelengths more efficiently than longer visible or infrared
wavelengths, so the best possible observations of the detached layer are
made in ultraviolet light.
The images in this view were taken by the Cassini narrow-angle camera on
May 5, 2005, at a distance of approximately 1.4 million kilometers
(900,000 miles) from Titan and at a sun-Titan-spacecraft, or phase, angle
of 137 degrees. Image scale is 8 kilometers (5 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European
Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory,
a division of the California Institute of Technology in Pasadena, manages
the mission for NASA's Science Mission Directorate, Washington, D.C. The
Cassini orbiter and its two onboard cameras were designed, developed and
assembled at JPL. The imaging operations center is based at the Space
Science Institute in Boulder, Colo.
