This false-color photograph of Neptune was made from Voyager 2 images taken in January 1996. The image reveals the presence of a ubiquitous haze that covers Neptune in a semitransparent layer. Near the center of the disk, sunlight passes through the haze and deeper into the atmosphere, where some wavelengths are absorbed by methane gas.

Global color mosaic of Triton, taken in 1989 by Voyager 2 during its flyby of the Neptune system. Color was synthesized by combining high-resolution images taken through orange, violet, and ultraviolet filters; these images were displayed as red, green, and blue images and combined to create this color version.
The Voyager 2 spacecraft took this color photo of Neptune's moon Triton on Aug. 24, 1989, at a range of 330,000 miles (530,000 kilometers). The image was made from pictures taken through the green, violet and ultraviolet filters. In this technique, regions that are highly reflective in the ultraviolet appear blue in color.
Neptune from Triton
This composite illustration is of the planet Neptune, as seen from its moon Triton. Neptune's south pole is to the left; clearly visible in the planets' southern hemisphere is a Great Dark Spot, a large anti-cyclonic storm system. This three-dimensional view was created using images from the Voyager spacecraft.
This view of the crescents of Neptune and Triton was acquired by Voyager 2 about three days after its Aug. 25, 1989, closest approach to Neptune. The spacecraft was about 3 million miles (4.86 million kilometers) from Neptune at the time.
The Pale Blue Dot
This narrow-angle color image of the Earth, dubbed 'Pale Blue Dot', is a part of the first ever 'portrait' of the solar system taken by Voyager 1. The spacecraft acquired a total of 60 frames for a mosaic of the solar system from a distance of more than 4 billion miles from Earth and about 32 degrees above the ecliptic.
Entering Interstellar Space
This artist's concept depicts NASA's Voyager 1 spacecraft entering interstellar space, or the space between stars, in August 2012.
Far from Home
The signal of NASA's Voyager 1 spacecraft -- the most distant human-made object -- was spotted from Earth in February 2013 by the National Radio Astronomy Observatory's 5,000-mile-wide (8,000-kilometer-wide) Very Long Baseline Array (VLBA), which links radio telescopes from Hawaii to St. Croix.
