For decades, Uranus and Neptune have carried the tidy label of “ice giants,” shorthand for worlds built mostly from frozen ...

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

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

Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to ...

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 ...

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 ...

A team of researchers from the University of Zurich and the NCCR PlanetS is challenging our understanding of the solar system ...

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

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.
