Can you spot the tiny Saturn moon in this NASA photo?

Get out your magnifying glass. A Cassini photo of Saturn's rings turns into a visual hunt for one of the planet's smallest moons.

Find the moon hiding in the rings.

The internet loves a good spot-the-object challenge, like finding birds in a tree or figuring out what's so weird about this brick wall.

NASA offers up its own version of an eye-puzzler with an image snapped by the Cassini spacecraft showing Saturn's rings. Look closely and you should be able to spot the moon Pan tucked in among the bright curves of the rings.

Saturn is lousy with moons. It has big moons, small moons and lumpy potato-shaped moons. All told, it has over 60 of them. Itsy-bitsy Pan, named for the Greek god of shepherds, is one of the smallest at a mere 17 miles (28 kilometers) across. It's also Saturn's innermost moon and carves out the Encke Gap, a dark path within the rings.

Cassini, which just entered the final year of its Saturn mission, took the image in early July from a distance of 840,000 miles (1.4 million kilometers) away from the planet. NASA released the photo Monday.

Still searching? Aim for the middle of the image and then look a little to the left to find the speck that is Pan.
