For forty years, a single fleeting encounter has shaped everything humanity believes about Uranus's magnetic environment — yet Voyager 2 arrived not on an ordinary day, but during solar-wind conditions so rare they occur only 4% of the time. The magnetosphere it measured was compressed by as much as 78%, a planet caught in an exceptional moment mistaken for a typical one. Science has been teaching the exception as the rule, and only now, through careful reexamination of that same mission's data, is the full weight of that misreading becoming clear.
