Over the course of Cassini's tenure in orbit around Saturn, it has beamed back numerous stunning images of the ringed planet. But perhaps the most stunning of which aren't of Saturn herself, but of her rings and other small satellites.

In the most recent addition, we have this great image of Saturn's rings and Tethys — one of its many strange and spectacular moons. Here, Tethys looks like it is hanging off the precipice to oblivion, just inches away from plummeting off the edge of Saturn's rings. Obviously, looks can be deceiving, as this is just a trick of perspective. Tethys itself is more than 100,000 miles higher than the rings are.

Delving deeper, two of Saturn's rings — the A-ring and the F-ring — are most prominent. The latter constitutes Saturn's outermost ring, which has repeatedly taken a beating over the years, mysteriously changing forms. The former, which is the ring that primarily appears to overlap with Tethys, is also one of the densest rings. Both are separated by what is called the Roche Division — a gap of more than 1,900 miles.
