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 ...

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.

Spaceship Neptune will be the vessel for this leisurely journey to a new perspective. ‘It’s the antithesis of a rocketship,’ says Poynter, ‘we will go to space at around 12 miles an hour, taking 2 ...

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 ...

Since then, the planet has only been visited once by spacecraft when, in 1989, Voyager 2 completed its 'Grand Tour' of our solar system's outermost planets. It took this image of Neptune and its moon ...

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.

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 ...

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) ...

Astronomers pointed the James Webb Space Telescope at a common kind of planet that's bigger than Earth but smaller than Neptune. What they saw wasn't what they expected.

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 ...

Set up in 2019 by Jane Poynter and Taber MacCallum, the outfit recently unveiled its new Spaceship Neptune capsule, a nine-seater craft designed to lift a crew of nine into the upper stratosphere, ...
