Summary:
- Researchers have discovered the explosive origins of high-energy electrons streaming from the Sun. These "superfast" electrons can travel at nearly the speed of light.
- The study found that these electrons are accelerated during solar flares, which are powerful explosions on the Sun's surface. The flares release a burst of energy that can propel the electrons to incredibly high speeds.
- Understanding the acceleration of these superfast electrons is important for predicting and mitigating the effects of solar storms, which can disrupt satellites, power grids, and other technologies on Earth.
