Illustration for article titled How Many Rings Do You See In This Image of Saturn?

We all know that Saturn is the planet with the rings, but how many did you think there were? In this photo, by the Cassini spacecraft on January 8, 2015, you can spend a good couple of hours trying to count them.

From NASA, an explanation of where structures inside the rings come from:

Structures in the rings can be caused by many things, but often times Saturn's many moons are the culprits. The dark gaps near the left edge of the A ring (the broad, outermost ring here) are caused by the moons (Pan and Daphnis) embedded in the gaps, while the wider Cassini division (dark area between the B ring and A ring here) is created by a resonance with the medium-sized moon Mimas (which orbits well outside the rings). Prometheus is seen orbiting just outside the A ring in the lower left quadrant of this image; the F ring can be faintly seen to the left of Prometheus.


And yet, we're still not entirely sure where the rings themselves come from.
