The previous consensus that magnetic dips in the magnetosheath can be attributed to non-propagating mirror waves is now shown to be oversimplified.
The electron density peaks well after the activity of the moon’s distinctive south polar ice plume reaches its maximum, but the cause of the lag remains puzzling.
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
Under a new editor in chief, the Journal of Geophysical Research: Space Physics is encouraging more scientific papers on space instrumentation, numerical models, and solar physics.
A planet’s magnetic field usually protects its atmosphere from being blown away by its star. But new research suggests Mars’s weak magnetic field may have helped its atmosphere escape.
The outgoing Editor in Chief of JGR: Space Physics reflects on his tenure and expresses his appreciation to all those who contributed to the success of the journal over recent years.
Spacecraft sometimes produce a form of electrical self-interference as they zip through plasmas in space—a previously unreported effect that may be lurking in old data sets.
A first usage of principal component analysis on Hubble images of Jupiter’s auroral ovals reveals the most common patterns, and machine learning classification reveals their physical causes.
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.
In the tightly confined region between the innermost ring and the planet’s upper atmosphere, the Cassini spacecraft observed signatures of a previously undetected current system.
