Titan’s south polar vortex stands out against the orange and blue haze layers that are characteristic of the hazy moon’s atmosphere. This view looks towards the trailing hemisphere of Titan (3,200 miles, or 5,150 km across). North on Titan is up and rotated 17 degrees to the left. Images taken using red, green and blue spectral filters were combined to create this natural-color view. The image was taken with the Cassini spacecraft narrow-angle camera on July 30, 2013. The view was acquired at a distance of approximately 895,000 miles (1.441 million km) from Titan. Image credit: NASA / JPL-Caltech / Space Science Institute.
