This celestial circle of light is produced by the glow of sunlight scattered through the
periphery of Titan's atmosphere as the Sun is occulted by Titan. It is the sum of all the
sunsets and sunrises taking place on Titan at once.
The intriguing structure of Titan's north polar "hood" can be seen at upper left. A thin,
detached, high-altitude global haze layer encircles the moon.
North on Titan (5,150 kilometers, 3,200 miles across) is up and rotated 23 degrees to
the left.
The image was taken in visible blue light with the Cassini spacecraft wide-angle
camera on June 29, 2007. The view was obtained at a distance of approximately
210,000 kilometers (131,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase,
angle of 167 degrees. Image scale is 12 kilometers (8 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.
