CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Hazy Halo

Cassini reveals Titan's upper-most atmospheric hazes, creating the appearance of a halo around Saturn's largest moon.

For a color view of the atmosphere's upper layers from another viewing geometry, see PIA 11468. Also visible in this image are hints of atmospheric banding around Titan's north pole. The north pole lies near the terminator about a quarter of the way inward from planet's limb at the top of this image. To learn more about the northern bands, see PIA 08928.

Most of the lit terrain seen here is on the anti-Saturn side of Titan (5150 kilometers, 3200 miles across). The image was taken in visible violet light with the Cassini spacecraft wide-angle camera on March 27, 2009. The view was acquired at a distance of approximately 196,000 kilometers (122,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 106 degrees. Image scale is 12 kilometers (7 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.

A very interesting variance in the image of the atmosphere when using visible violet light instead of red, blue and green spectral filters as in the image "Hazy Ring of Titan's sky. Here, the presence of a uniform upper most atmosphere is clearly visible.
