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 ...

We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these planets be called "rocky giants" instead. When you purchase through links on our ...

The Hubble Space Telescope has peered at Uranus, left, and Neptune to study the so-called "ice giant" planets, but little is known about their interior composition. Credit: NASA / ESA / M. Showalter / ...

A team of researchers from the University of Zurich and the NCCR PlanetS is challenging our understanding of the solar system planets' interior. The composition of Uranus and Neptune, the two ...

A novel unified hydrodynamic model proposes a single mechanism to explain the contrasting equatorial jet stream directions on gas giants (eastward on Jupiter/Saturn) and ice giants (westward on Uranus ...

Our solar system contains three types of planets. Between the four terrestrial planets–Mercury, Venus, Earth, and Mars–and the distant ice giants of Neptune and Uranus, sit two gas giants: Saturn and ...
