This mosaic of Jupiter's ring system was acquired by NASA's Galileo spacecraft when the Sun was behind the planet, and the
spacecraft was in Jupiter's shadow peering back toward the Sun.
In such a configuration, very small dust-sized particles are accentuated so both the ring particles and the smallest particles in the
upper atmosphere of Jupiter are highlighted. Such small particles are believed to have human-scale lifetimes, i.e., very brief
compared to the solar system's age.
Jupiter's ring system is composed of three parts: a flat main ring, a toroidal halo interior to the main ring, and the gossamer ring,
which lies exterior to the main ring. Only the main ring and a hint of the surrounding halo can be seen in this mosaic. In order to
see the less dense components (the outer halo and gossamer ring) the images must be overexposed with respect to the main
This composite of two mosaics was taken through the clear filter (610 nanometers) of the solid state imaging (CCD) system on
November 9, 1996, during Galileo's third orbit of Jupiter. The ring was approximately 2,300,000 kilometers away. The resolution
is approximately 46 kilometers per picture element from right to left; however, because the spacecraft was only about 0.5
degrees above the ring plane, the image is highly foreshortened in the vertical direction. The vertical bright arcs in the middle of
the ring mosaics show the edges of Jupiter and are composed of images obtained by NASA's Voyager spacecraft in 1979.
