Ice-giant planet was having a bad day when Voyager came calling
Briefly

For nearly four decades, scientists have puzzled over Uranus’s strange magnetosphere, which they believed to be a unique phenomenon in our solar system. Recent observations suggest that previous interpretations may have been skewed by a temporary disruption, indicating that the planet's magnetic field is less peculiar than once thought.
The confusion surrounding the magnetosphere of Uranus stems from a particular observation by Voyager, which may have revealed an atypical state of magnetic activity. This has led to a reevaluation of the characteristics and behavior of Uranus's magnetic environment.
