 The Sunlit Edge of Saturn's Largest Moon Is Hauntingly Beautiful

This ghostly image shows the sunlit edge of Titan, Saturn's largest moon. Captured by Cassini, it's unilluminated atmosphere provides a hazy yet breathtaking view.

Visible in the darkness is the south polar vortex of the moon, because its clouds are at a higher altitude than the rest of the atmosphere. Snapped from 1.3 million kilometres away, the image makes use of a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometres to capture the beauty of Titan. It worked. [NASA]
