Solar wind plasma data captured by the Tianwen-1 probe while in transit to Mars represent an important step toward a new era of cooperative Martian space exploration.
Observations reveal a connection between auroral particle precipitation and scintillation, indicating that the ionospheric E-region is a key source region for phase scintillation at auroral latitudes.
Analysis of multiple satellite data has revealed a striking connection between K-H waves on the magnetopause, surface waves in the hot zone near the plasmapause, and auroral undulations.
Energetic electrons are accelerated directly by magnetic reconnections and can act as tracers of large-scale magnetic field conditions.
When plasma particle velocity distributions have multiple, distinct parts, treating each as a separate beam may yield more intuitive results.
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.
Naval radio signals may cause the formation of a barrier observed during geomagnetic storms that is seemingly impenetrable by relativistic electrons.
Terry Zixu Liu received the 2019 Fred L. Scarf Award at AGU’s Fall Meeting 2019, held 9–13 December in San Francisco, Calif. The award is given annually to “one honoree in recognition of an outstanding dissertation that contributes directly to solar–planetary science.”
NASA’s Juno spacecraft is “hearing whistles” all over the place on Jupiter, a type of natural plasma waves called whistlers that are sometimes associated with atmospheric lightning.
An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.
