   Explanation: [6]Saturn is the most distant planet of the Solar System
   [7]easily visible to the unaided eye. With this extraordinary,
   long-term astro-imaging project begun in 1993, you can follow the
   ringed gas giant for one Saturn year [8]as it wanders once around the
   [9]ecliptic plane, finishing a single orbit around the Sun by 2022.
   Constructed from individual images made over 29 Earth years, the split
   panorama is centered along the ecliptic and crossed by the plane of our
   Milky Way galaxy. Saturn's position in 1993 is at the right side, upper
   panel in the constellation Capricornus and progresses toward the left.
   It returns to the spot in Capricornus at left in the lower panel in
   2022. The consistent imaging shows Saturn appears slightly brighter
   during the years 2000-2005 and 2015-2019, periods when its beautiful
   rings were tilted more [10]face-on to planet Earth.
