Bright clouds circumscribe Titan's north polar region—a frigid land
of methane seas.
The clouds seen in this image and other recent Cassini spacecraft views
are at higher latitudes than similar streak-like clouds observed in the
southern hemisphere (see PIA08966). Scientists are working to understand
why such clouds appear preferentially at certain latitudes on Saturn's
largest moon.
While the streaks that grace Titan's southern hemisphere are often seen at
40 degrees south latitude, similar to Wellington, New Zealand, the streaks
in the northern hemisphere are farther from the equator, near 56 degrees
north latitude, which is similar to Glasgow, Scotland.
North on Titan (5,150 kilometers, 3,200 miles across) is up and rotated 16
degrees to the right.
The image was taken with the Cassini spacecraft narrow-angle camera on Sept. 30, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 938 nanometers. The view was obtained at a distance of approximately 1.2 million kilometers (776,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 71 degrees. Image scale is 7 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.
