Every 29.5 years, Saturn's rings seem to disappear to us here on Earth. This is because Saturn tilts on its axis, just like Earth. When Saturn reaches the mid point of its tilt, the rings are in a flat plane with Earth, making them disappear from our view. During this time, researchers can search for more moons around Saturn because the glare of the rings is absent. See below photo. Saturn's moon Rhea is seen below the rings.
