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.
Very Low Frequency transmitters used for communications with submarines modify the dynamics of energetic electrons in the inner radiation belt and the slot region.
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.
In a new study, the enigmatic gravity waves were seen most frequently at equatorial latitudes and propagating from the winter to the summer hemisphere.
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
Green-line arc is found to be embedded within large-scale upward field aligned currents while red-line-only arc is found to be associated with low-energy precipitation bursts.
Sometimes the conditions in the solar wind can change dramatically over short distances. Satellite observations of these features show that they’re more complex than previously thought.
An analysis of 5 decades of satellite data has pieced together the most comprehensive picture yet of substorms, the magnetic disturbances that cause surges of aurora.
A new study suggests alternative explanations for Io’s unusual magnetic field.
A new classification scheme helps researchers distinguish what accelerates the electrons that create auroras.
