See that small pixel? That's an entire moon you're looking at! Peeking between the rings of Saturn is the tiny saucer-shaped moon Atlas, as viewed from the Cassini spacecraft. The image is pretty, but there's also a scientific reason to watch the planet's many moons while moving around the rings.
"Although the sunlight at Saturn's distance is feeble compared to that at the Earth, objects cut off from the Sun within Saturn's shadow cool off considerably," NASA stated.
"Scientists study how the moons around Saturn cool and warm as they enter and leave Saturn's shadow to better understand the physical properties of Saturn's moons."
And if you look at Atlas close-up, it looks a little like a flying saucer! The moon is only 20 miles (32 km) across, which is a bit shy of the length of a marathon. The Voyager 1 team spotted the moon in 1980 when the spacecraft zoomed through the system. You can learn more about Saturn's moons here.
Cassini is still in excellent health (it arrived at Saturn in 2004, and has been in space since 1997), and scientists are eagerly getting ready for when Saturn gets to its summer solstice in 2017. Among the things being looked at is a hurricane at Saturn's north pole.
