New images from the space-based observatory offer a novel view of the planet in infrared. By Jonathan O’Callaghan No spacecraft has visited Neptune since 1989, when the NASA probe Voyager 2 flew ...

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.

A newly discovered distant mini-Neptune planet may possess its own atmosphere, ocean, or a combination of the two, even if they don't last for long.

The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar system. Neptune is considered an "ice giant" because of its internal chemical composition.

With its vanishing clouds and now a large dark spot, the planet Neptune appears to be going through some things. Here’s a bit about why the eighth planet in our solar system is causing all this ...

Our Solar System is home to eight extraordinary planets, each with its own unique features, mysteries, and beauty. This cosmic journey takes you from the Sun-scorched surface of Mercury to the icy ...

This artist's concept depicts the planet GJ 1214 b, a "mini-Neptune" with what is likely a steamy, hazy atmosphere. NASA/JPL-Caltech/R. Hurt (IPAC) ...

The images of Uranus, the seventh planet from the sun, and Neptune, the eighth planet, were collected in 1986 and 1989, respectively, as NASA's Voyager 2 spacecraft headed out of the solar system.

The images taken by Voyager 2 when it passed Neptune in 1989 were originally processed to better reveal its distinctive features, but as a result they made the planet look too blue. P. Irwin ...

The celestial body, officially named 2017 OF201, is a trans-Neptunian object (TNO)—a minor planet beyond Neptune’s orbit—and one of the most distant visible objects in the solar system.

So a priori, it’s possible a planet might exist in the cold, dark depths of our own solar system. It could even be quite large, the size of an ice giant like Neptune. On supporting science ...
