Earth, Jupiter, and Saturn all have dipolar magnetic fields, meaning they have a north and south pole — the type of configuration we’re obviously used to. But Uranus and Neptune don’t.

Both of the ice giant planets, Uranus and Neptune, lacked what's known as a "dipole magnetic field." This was in stark contrast to our own rocky world, as well as the two gas giants Jupitar and ...

This bizarre structure could explain why Uranus and Neptune have such unusual magnetic fields. The outermost layers of Uranus and Neptune consist mainly of clouds of hydrogen, helium and methane ...

A Puzzle of Magnetic Fields When Voyager 2 visited Uranus and Neptune in the late 1980s, it uncovered surprising magnetic anomalies. Unlike Earth's dipolar magnetic field, which is created by ...

That included some oddities, such as the fact that Uranus’ magnetic field was both highly tilted and offset. By comparing measurements of that field, astronomers were able to estimate the planet ...

Uranus’s strange magnetic field may be much less weird than astronomers first thought, which means its largest moons could be much more active, and even perhaps have global oceans. Our only ...

Voyager 2’s observations of Uranus’ magnetosphere defied the way astronomers understand how magnetic fields trap energetic particles and their radiation. The astronomers were puzzled by the ...

Initial analysis of the Voyager 2 data suggested that the planet’s magnetosphere—the area around Uranus dominated by its magnetic field—was devoid of plasma, which is present in other ...
