The Ice Giants' Magnetic Fields are Very Strange Compared to Earth's

Uranus and Neptune, the Solar System's ice giants, have interiors unlike the other planets. As a result, they also have magnetic fields unlike the others. They're messy and tilted, and Voyager 2, the only spacecraft to even flyby them, showed us how messy they are. New research uses models to try to understand what's going on with the pair of planets and their weird fields, and found that it's likely they change on very short timescales. They could already be much different than when Voyager 2 visited in the late 1980s.
