Nearly four decades after Voyager 2 skimmed past Uranus, a fresh look at its measurements is reshaping what scientists ...

New models suggest Uranus and Neptune may hold far more rock than expected, raising questions about how these distant planets formed.

Although they are technically gas giants, Uranus and Neptune are referred to as "ice giants" due to their composition.

During its 1986 observation of the planet in the first and only flyby, the spacecraft measured a surprisingly strong electron ...

Fresh simulations show there is a chance Uranus and Neptune might actually be rock-rich worlds wrapped in thinner icy layers.

Powerful waves unleashed by solar storms could be the key to understanding extreme radiation. (SwRI) researchers now think ...

When Voyager 2 flew by Neptune in 1989, it sent back images that were processed to better reveal features like bands and a dark spot. But a new study says it's actually a greener planet.

To date, the Voyager 2 probe has provided the only direct measurements of the radiation environment at Uranus. This led to ...

More than 30 years have passed since the Voyager 2 fly-bys of Uranus and Neptune. I discuss a range of lessons learned from Voyager, broadly grouped into process, planning, and people. In terms of ...

Thirty years ago, on Aug. 25, 1989, NASA’s Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system’s eighth planet. Marking the end of the Voyager ...

Why it's so special: Only one spacecraft has ever visited the eighth and most distant planet from the sun. On Aug. 25, 1989, NASA's Voyager 2 spacecraft took the first-ever close-up images of Neptune.
