Earth's Radiation Belts as Measured by NASA's POLAR Satellite
This series of 3D images shows how of the Earth's radiation belts can change in size and intensity, waxing and waning in response to solar activity and acceleration inside Earth's magnetosphere. At times the belts can almost disappear, while at other times new belts can be created. The images are drawn from data on energetic particles, as collected by NASA's Polar spacecraft.
