As planets and stars travel through the streams of charged particles flowing across space, their magnetic fields act like obstacles; incoming particles are slowed and deflected, forming a boundary called the bow shock; just ahead of this boundary lies the foreshock, a variable region where magnetic conditions can accelerate some particles to nearly the speed of light.
