probe Voyager 1 during its closest encounter with Saturn, sent stunning images of the rings, revealing that, in fact, hundreds of other small rings were between the old rings A, B and C, thus invalidating the theory that considered these three rings as a single disk of matter. Voyager 1 has revealed further that the F ring, discovered in 1979 by the Pioneer 11 is in turn subdivided into three parts, traversed by small rings and confirmed the existence of the D ring that was photographed during passage through Saturn's shadow. Also the faint E ring, visible from Earth every two years, when Saturn is in a certain position on our planet, has been observed by Voyager 1.
