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.
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.
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.
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.
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
Force imbalance between Jupiter’s ionosphere and magnetosphere leads to wave generation to release this stress, but the waves also accelerate particles, causing aurora and heating.
A solar cycle of data was scoured for the biggest electron energy fluxes seen in the Mars space environment.
A new empirical model of energetic electrons from Van Allen Probes data includes pitch angle analysis, revealing insights about radiation belt energization and loss processes.
Pancaking and erosion can explain a lot of the structural change in magnetic flux ropes as they fly evolve during their supersonic flight through the inner solar system.
Yes, Earth has a tail, a magnetotail, and there is debate about how much Earth’s upper atmosphere plays a role in the controlling the dynamics of this region of space.
