Scientists Finally Solve the Mystery of the Sun’s Fastest Particles

The Sun acts as the Solar System’s ultimate particle accelerator, hurling out streams of high-speed electrons. Thanks to ESA’s Solar Orbiter, scientists have traced these energetic electrons back to their solar origins, revealing two distinct types: sudden bursts from solar flares and prolonged waves from massive eruptions called coronal mass ejections (CMEs). Solar-Powered Particle Accelerator [...]
