Though not as damaging as extreme space weather events, showers of plasma jets hit Earth’s magnetic shield every day—yet we’re only beginning to understand their effects.
Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.
A new study supports the idea of a “helicity barrier” influencing the fluctuating stream of interplanetary plasma.
Coronal mass ejections from stars have eluded easy observation, so scientists are looking at what’s left behind.
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.
