This picture of Neptune was taken by Voyager 2 less than five days before the probe’s closest approach of the planet on Aug. 25, 1989. The picture shows the “Great Dark Spot” — a storm in Neptune’s atmosphere — and the bright, light-blue smudge of clouds that accompanies the storm. Credits: NASA/JPL-Caltech

   35 years ago, on Aug 25, 1989, the venerable Voyager 2 spacecraft gave humanity the first close look at planet Neptune.

   Voyager 2 swung by at 4,950 km alt above the north pole. 5 hours later, it performed a close fly-by of Triton, Neptune's largest moon, passing within ~40,000 km.

   V2 discovered previously unknown Neptunian rings, and confirmed 6 new moons - Despina, Galatea, Larissa, Proteus, Naiad and Thalassa.

   This picture of Neptune was taken on Aug 22, 1989.
