The Van Allen radiation belts are massive, doughnut-shaped regions of charged particles trapped by Earth's magnetic field. When the Sun blasts Earth with strong solar wind or solar storms, energetic particles are injected into these belts, increasing their overall energy levels. Now, the Van Allen radiation belts are "fully charged," according to space weather observer Stefan Burns. He warns that these belts of energetic particles have been building up due to repeated solar storms over the past few months. "The next solar storm to hit could cause…
