Summary

Story summary

NASA's Voyager 2 conducted a flyby of Uranus in January 1986, revealing unexpectedly high radiation levels around the planet.
New research from the Southwest Research Institute links these levels to a co-rotating interaction region (CIR) in the solar wind.
The disturbance likely accelerated electrons and strengthened Uranus's radiation belts.
Dr. Robert Allen of the Southwest Research Institute emphasizes a dedicated Uranus mission to study its magnetosphere and Neptune.
