Under extreme planetary conditions, water turns into a strange, electricity-conducting solid hidden deep inside giant planets.

Because Uranus and Neptune are so far away, scientists only have educated guesses about the combination of ices and gases that make up these ice giants. While the general understanding is that these ...

Neptune is fondly known for being a rich blue and Uranus green -- but a new study has revealed that the two ice giants are actually far closer in color than typically thought. The correct shades of ...

Voyager 2 data from Uranus and Neptune revealed their magnetic fields are non-dipolar and disordered, a stark contrast to the dipolar fields observed on Earth, Jupiter, and Saturn. Astronomer Burkhard ...

An image of Uranus on the left and Neptune on the right. They look almost indiscernible as they're both light blues. In the summer of 1989, from a remote expanse of our solar system where sunlight is ...

The way most of the public thinks Neptune and Uranus look, especially "big blue" Neptune, does not likely resemble what astronomers say these icy giant worlds actually look like. The planets of Uranus ...

For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from frozen water, ammonia and methane wrapped in hydrogen and helium. A new ...

Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought. The correct shades of ...

For decades, Uranus and Neptune have carried the tidy label of “ice giants,” shorthand for worlds built mostly from frozen water, ammonia and methane. A new wave of modeling work is now challenging ...

Uranus and Neptune have been called the “ice giants” for decades. But in new research, that nickname might be more a misnomer than anything. A study by the lead researchers astrophysicists Luca Morf ...

Astronomers with the International Astronomical Union have discovered three previously unknown moons at the farthest planets of our solar system — two circling Neptune and one around Uranus. The moons ...
