In the latest shutdown, the cosmic ray subsystem experiment on Voyager 1 and Voyager 2’s low-energy charged particle ...

A unique view: These pictures of Neptune were obtained by NASA Voyager 2 on April 26,1989. The picture on the top was taken five hours after that at bottom, during which time the planet rotated ...

The icy giants Uranus and Neptune, in particular, were studied for the first and only time in history by Voyager 2, while successful observations of Jupiter and Saturn were the basis for ...

Finally, Voyager 2 put an end to those arguments once and for all, after it saw Neptune’s ring in its full glory close up. It turns out, Neptune’s ring is clumpy, so some sections are harder ...

Voyager 2, NASA's longest-running mission, explored Neptune during a historic encounter on Aug. 25, 1989, sending back humanity's first close-ups of the planet.

Triton and Pluto have both been visited once by spacecraft, the former by NASA’s passing Voyager 2 in 1989 and the latter by NASA’s New Horizons probe in 2015.

At this close distance, Neptune will appear at its largest apparent size for 2022, appearing at 2.34 arcseconds across. It will reach magnitude +7.8 at its brightest in opposition.

Back in the late 1900s, the images Voyager 2 recorded of Uranus and Neptune were in single colors combined to create composite images that showed the planets to be cyan and azure, respectively.

Voyager 2 conducted a flyby of Uranus in 1986, and the images revealed a planet with a more pale cyan or blue color. The vessel flew by Neptune in 1989 and the imagery showed a planet with a rich ...

In 1989, Voyager 2 became the first and only spacecraft to ever fly by Neptune, and images from that mission famously show a planet that's a deep azure color. But in reality, Neptune is far more ...

Neptune, long believed to be dark blue, is actually very pale like Uranus, scientists say. They used modern telescopes to re-assess artificially enhanced images taken by NASA's Voyager 2 probe.
