Astronomers have used telescope data to color-correct Voyager 2 images of Neptune and Uranus, revealing that the planets have a similar greenish blue hue.

The movie is composed of natural- and enhanced-color views of Neptune that were assembled from images taken in 14 different colored filters, which allow atmospheric features to be seen above Neptune's methane haze. Neptune is shown in natural color with its largest satellite, Triton, as it orbits the planet. Triton orbits in a "backwards" or ...
Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar ...
The Great Dark Spot in exaggerated color as seen from Voyager 2. The Great Dark Spot (also known as GDS-89, for Great Dark Spot, 1989) was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. In 1989, GDS-89 was the first Great Dark Spot on Neptune to be observed by NASA's Voyager 2 space probe.
Three of Neptune's moons—Proteus, Nereid, and Triton—were photographed in detail, of which only the last two had been known prior to the visit. Proteus proved to be an ellipsoid, as large as gravity allows an ellipsoid body to become without rounding into a sphere, and appeared almost as dark as soot in color.
It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin, hazy atmosphere. Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so.
