The team found a transient but large-scale phenomenon upstream of the earth’s bow shock. During this event, electrons in the earth’s foreshock seemed to acquire more than 500 keV of energy.

This stunning image features a deep field view of the Cassiopeia constellation where the two small planetary nebulas can be ...
