    Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn has a ring system that consists of nine continuous main rings and three discontinuous arcs, composed mostly of ice particles with a smaller amount of rocky debris and dust. Sixty-two known moons orbit the planet; fifty-three are officially named.

Images from the Cassini spacecraft currently orbiting Saturn have uncovered long rows of huge sand dunes near Titan's equator that rise as high as 300 meters. Shadows indicate that most dune shapes are created by wind blowing from the west.

Why isn't spiral galaxy M66 symmetric? Usually density waves of gas, dust, and newly formed stars circle a spiral galaxy's center and create a nearly symmetric galaxy. The differences between M66's spiral arms and the apparent displacement of its nucleus are all likely caused by previous close interactions and the tidal gravitational pulls of nearby galaxy neighbors M65 and NGC 3628.

In July of 1994, pieces of Comet Shoemaker-Levy 9, aka the "string of pearls" comet, collided with the Jupiter. As the comet fragments smashed into Jupiter, explosions scattered large quantities of dusty cometary debris into the Jovian atmosphere. The clouds of debris created the multiple dark smudges visible in this picture. Jupiter's rotation causes the successive impact sites to be strung out along the cloud bands while the strong winds cause the appearance of the smudges to change with time.
