   Explanation: [6]Ice giant Neptune is faint in Earth's night sky. Some
   30 times farther from the Sun than our fair planet, telescopes are
   needed to [7]catch a glimpse of the dim and distant world. This
   dramatic view of [8]Neptune's night just isn't possible for telescopes
   in the vicinity of planet Earth though. Peering out from the inner
   Solar System they can only bring [9]Neptune's day side into view. In
   fact this night side image with Neptune's slender crescent next to the
   crescent of its large moon Triton was captured by Voyager 2. Launched
   from planet Earth in 1977 the [10]Voyager 2 spacecraft made a close fly
   by of the Solar System's outermost planet in 1989, looking back on
   Neptune as the robotic spacecraft continued its [11]voyage to
   interstellar space.
