Titan's Senkyo Region and South Polar Vortex


The Cassini spacecraft simultaneously peers through the haze in Titan's equatorial region down to its surface and captures the vortex of clouds hovering over its south pole just to the right of the terminator on the moon's dark side.

The dark region near Titan's equator is Senkyo. See PIA11636 for a closer view of Senkyo and to learn more. For a color image of the south polar vortex on Titan, see PIA14919. For a movie of the vortex, see PIA14920.

Lit terrain seen here is on the Saturn-facing hemisphere of Titan (3,200 miles, or 5,150 kilometers across). North on Titan is up and rotated 11 degrees to the left. The image was taken with the Cassini spacecraft narrow-angle camera on September 20, 2012 using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers.

The view was obtained at a distance of approximately 1.8 million miles (2.9 million kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 84 degrees. Image scale is 11 miles (17 kilometers) per pixel.
