Machine Learning Helps to Solve Problems in Heliophysics
A new special collection invites papers pertaining to the use of machine learning techniques in all sub-fields of heliophysics.
Modification of Energetic Particles Loss Cone During Storms
The loss cone of energetic particles in the Earth’s inner magnetosphere is substantially modified during disturbed times, with important implications for the radiation-belt and ring current modeling.
The Auroral E-region is a Source for Ionospheric Scintillation
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.
Wind: Discoveries and Impacts of a Venerable Spacecraft
Wind has been one of the most robust, diverse, long-lasting, and impactful heliophysics missions ever to have been carried out.
Taking Stock of Cosmic Rays in the Solar System
Scientists seek to understand the elusive properties of stellar and galactic cosmic rays before searching for life on exoplanets.
A New Approach to Characterizing Space Plasmas
When plasma particle velocity distributions have multiple, distinct parts, treating each as a separate beam may yield more intuitive results.
All Hands on Deck to Catch Ion Cyclotron Waves
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.
Ghostly Particles from the Sun Confirm Nuclear Fusion
Using the Borexino particle detector—located deep underground in Italy—researchers spot elusive neutrinos from the Sun’s CNO cycle.
