Titan - NASA
Titan, the largest moon of the planet Saturn

This subtle and smoothed out infrared image of Saturn’s largest moon, Titan was taken by Cassini spacecraft’s narrow-angle camera and shows us a band around the Titan’s north pole. The mind boggling aspect of this image is that it was taken while Cassini was approximately 1.5 million miles (2.4 million kilometers) from Titan, using a spectral filter which preferentially allows through wavelengths of near-infrared light centered at 889 nanometers.
