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 ...

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

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

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

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

New research suggests Uranus and Neptune may not be true ice giants, with rocky interiors dominating instead, challenging ...

A new study suggests that Uranus and Neptune may not be ice-rich planets after all. Researchers from the University of Zurich propose that these distant worlds could be dominated by rock, challenging ...

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

Each year, as we cross into January, there is a sense of excitement and wonder about what the coming months may bring. Will ...

The cold and remote planets originally earned their label of "ice giants" to contrast their interiors from those of Jupiter ...

Far from the Sun, Uranus sits tipped on its side, carrying a magnetic system unlike any other planet’s. Its equator tilts ...
