For decades, school posters and science museum displays have grouped Uranus and Neptune together as “ice giants,” a tidy ...

Billions of miles (kilometers) from the Sun, Uranus and Neptune are the most distant planets in our Solar System. Long ...

Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by ...

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 ...

Researchers have uncovered evidence that Uranus and Neptune could be far rockier on the inside than anyone expected.

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 ...

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 ...

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 ...

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

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Researchers have now developed a single atmospheric model that matches observations of both planets. The ...

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