A new photo taken by a spacecraft near Saturn shows a small moon making waves in the planet's rings.
The photo, captured by the Cassini spacecraft on Jan. 16, reveals the moon Daphnis as it makes its way around the huge world, orbiting within a gap in the planet's distinctive rings.
SEE ALSO:Actual footage shows what it was like to land on Saturn's moon TitanCassini was 17,000 miles miles away from Daphnis when it snapped this shot, and according to NASA, it's our closest-ever view of the small world.
"The little moon's gravity raises waves in the edges of the gap in both the horizontal and vertical directions," NASA said in a statement.
In 2009, Cassini caught sight of those waves from a different angle.

For example, you can see a little wispy wave following behind Daphnis in its orbit. NASA thinks that the structure may have formed when the moon captured some material from Saturn's rings and started trailing it behind itself.
NASA is also learning more about what Daphnis -- which is only about 5 miles wide -- looks like in general thanks to this image.
An apparently, Daphnis looks like a member of Saturn's family.

The little moon has also inspired astrophysicist Katie Mack to create a pretty great meme that lends a little perspective to our place in the universe and on Earth.

Cassini is almost at the end of its more than 10-year mission exploring Saturn and its 53 known moons.
The spacecraft will make its planned crash into Saturn's atmosphere in September, ending its mission after launching from Earth in 1997.
