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

Nobody knows how electrons gain the relativistic speed required for high-energy cosmic events. A new study provides a possible explanation.

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 displacements of the bow shock moving back and forth along the sun-earth line are observed. Electron energy shows enhancements from ∼50 keV in the FB to ∼100 keV in the HFA core, suggesting ...

The strongest magnetic field directly measured in the universe to date The study uses real-time data from the MMS mission and the THEMIS/ARTEMIS mission to observe a large-scale, time-dependent (i.e., ...

An example effect is the bow shock created as the magnetosphere passes ... an encounter with a magnetic reconnection site in the Earth’s magnetosphere.
