A new book describes recent results defining the many pathways and foreshock, bow shock, magnetosheath, and magnetopause phenomena connecting the solar wind to the dayside magnetosphere.
The nightside ionosphere, at latitudes away from the auroral zone, should have very little charged particle density, but it doesn’t. A new comprehensive study of satellite data explains why.
Scientists capture the first complete image of Earth’s luminous geocorona and prove its ecliptic north–south symmetry.
In forecasting the effects of solar storms, understanding how they subside—and not just how they arrive—will be crucial.
An analysis of the electromagnetic "hiss" that surrounds Earth reveals it's not just static; there's a signal hidden within, which may help scientists uncover its source.
Satellite observations explain why magnetosonic waves can be found in regions far from where they originate.
Researchers find that a model of the Earth’s plasmasphere developed in the 1960s is outdated and inaccurate.
