Slicing the Arc

The bright arc within Saturn's G ring is shown truncated by the shadow of the planet at the bottom of this image.Although it can't be seen here, the tiny moonlet Aegaeon (formerly known as S/2008 S 1) orbits within the bright arc. See PIA11148 to learn more. This view looks toward the northern, sunlit side of the rings from about 4 degrees above the ringplane. Many background stars are visible
