Figure 1: Electron acceleration in the outer Van Allen radiation belt. Although the present results may provide a resolution to the debate over which mechanism is the dominant cause of ...

Earth grew a pair of extra "radiation belts" after a supercharged solar storm rocked our planet's magnetic field last year, data from a resurrected NASA spacecraft reveal. And one of the invisible ...

Electrons in a Van Allen radiation belt (blue) encounter whistler waves (purple) and are sent raining toward the north pole (red). THEMIS satellites are seen near the radiation belt, while UCLA ...

These high-energy particles in space make up what are known as the Van Allen radiation belts, and their discovery was one of the first of the space age. A new study from my research team has found ...

Caption The twin Van Allen Probes have spent more than six years orbiting through Earth's radiation belts. Orbit changes in early 2019 will ensure that the spacecraft eventually de-orbit and ...

In particular, recent work has focused on wave-particle interactions, solar wind-magnetosphere interactions, and energetic particle dynamics in Earth’s Van Allen radiation belts through analysis of ...

It triggered unexpected phenomena in the space surrounding our planet. This solar storm not only disrupted GPS communications but also created two new temporary radiation belts around Earth. These ...
