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

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

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

The giant planets weren't always where we find them today. Jupiter, Saturn, Uranus and Neptune formed in a more compact ...

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

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

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 ...
