The outermost layers of Uranus and Neptune consist mainly of clouds of hydrogen, helium and methane, which absorbs red light, giving these planets their blue hues.

When Voyager 2 visited Uranus and Neptune in the late 1980s, ... This disorganization suggested a lack of deep convective layers typically required to generate a global dipole magnetic field.

“Uranus and Neptune have disordered magnetic fields because they produce these fields in a thin water-rich layer in their mantles while our Earth generates its magnetic field in the core ...

These immiscible layers would explain why neither Uranus nor Neptune has a magnetic field like Earth's. That was one of the surprising discoveries about our solar system’s ice giants made by the ...

Uranus and Neptune have weird magnetic fields — this might be why New models using Voyager 2 data from the 1980s show that separate layers in the planets’ mantles could be creating disordered ...

This C-N-H layer is almost like a plastic polymer, Militzer explains, and cannot support even a disorganized magnetic field – unlike the upper, water-rich layer, which likely convects. A future ...

This process, however, is absent from Uranus and Neptune.So, scientists wondered: Why would that be? For the last two decades, researchers had speculated that this was because layers of material ...

Sub-Neptune planets, which are about the size of Uranus and Neptune, are among the most common exoplanets observed. Militzer’s model suggests that their interiors might also have these non-mixing ...

These immiscible layers would explain why neither Uranus nor Neptune has a magnetic field like Earth's. That was one of the surprising discoveries about our solar system 's ice giants made by the ...

An exploded view of an ice giant planet such as Uranus or Neptune, with its hidden water-rich layer (blue) that has separated from a deeper layer of hot, high-pressure carbon, nitrogen and ...
