PIA18291: Mimicking the Moon (NASA/JPL-Caltech/Space Science Institute)

This image from the Cassini orbiter shows Saturn and it’s moon Titan, both in a crescent phase. This image has a scientific purpose, as well as being astronomically hot - scientists can tell all kinds of exciting things about atmospheric conditions by looking at how the light acts.

… As if you would expect anything different from people who can build a robot and then fire it a quarter of the way across the solar system for a happy snap.
