How solar flares accelerate charged particles into super high speeds
Scientists have made another step toward determining how solar flares accelerate charged particles like electrons and protons to speeds of almost the order of light. The new capabilities of the National Science Foundation's Karl G. Jansky Very Large Array (VLA)…
