Cassini's finely tuned vision reveals seasonal differences in the global
haze that envelopes Titan in this narrow angle camera image taken on Oct.
24, 2004. The picture was taken through a filter sensitive to strong
absorption by methane gas (wavelengths centered at 889 nanometers). Here,
the northern hemisphere of Titan is notably brighter than the southern
hemisphere, because there is more haze in the north. The presence of haze
in the northern hemisphere was also observed in images returned by NASA's
Voyager spacecraft in 1981. The haze distribution was reversed, north to
south, in observations taken by NASA's Hubble Space Telescope from 1994
to 2000.
The image was taken from a distance of 1.08 million kilometers (675,000
miles) from Titan. The image scale is 6.52 kilometers (4.05 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 Cassini-Huygens mission for NASA's Office of Space
Science, Washington, D.C. The Cassini orbiter and its two onboard cameras,
were designed, developed and assembled at JPL. The imaging team is based
at the Space Science Institute, Boulder, Colo.
