Sure, you've seen a crescent moon from Earth, but I bet you've never seen three.
NASA's Cassini spacecraft captured not just one but three crescent moons in a single photo. Saturn's moons Titan, Mimas and Rhea all make an appearance in the new image released by NASA Monday.
Although each of the three moons looks like a crescent from Cassini's perspective, Titan, Mimas and Rhea do have distinctive differences even when seen in this phase.
In a statement NASA said the largest moon in the picture, Titan, looks fuzzy because only the cloud layers are visible. The moon's atmosphere refracts light around the moon, making the crescent wrap around the moon further.
The space agency added Rhea in the upper left looks rough because its icy surface is heavily cratered.
