Grand cosmic events demand electrons to reach relativistic speeds. A new study explains where they get their initial energy from.

During this event, electrons in Earth's foreshock region—an area where the solar wind is predisturbed by its interaction with the bow shock—reached unprecedented energy levels, surpassing 500 keV.

The magnetosheath, the region downstream of the Earth's bow shock, is one of the most typical turbulent environments and is very suitable for studying turbulence dissipation. By analyzing ...
