The peculiar layers could explain the ice giants' magnetic peculiarities. Uranus (left) and Neptune (right) are the ice blue giants in the outer Solar System. Image credit: Patrick Irwin/University of Oxford/NASA Uranus and Neptune were only visited once by human spacecraft when Voyager 2 passed by them almost 40 years ago. During those visits, scientists measured peculiar magnetic fields unlike those seen around other planets. A recent paper suggests that the Uranus measurements might have been messed up by the Sun, but in general, it has been difficult to explain the behavior. New research suggests that the magnetic weirdness might...
