A new simulation of the Earth’s electron radiation belts captures large-scale variations over nearly three solar cycles, and replicates primary cyclical features and extreme behaviors.
A new study identifies possible precursors to space weather in the regions encircling sunspots.
This prolific researcher helped us understand the interactions of the solar wind and coronal mass ejections with Earth’s magnetic field.
Several international initiatives are working to stitch together data describing solar forcing of Earth’s climate. Their objective is to improve understanding of climate response to solar variability.
This pioneer in high-energy solar physics devised instruments for observing solar and cosmic ray emissions with which he detected, for the first time, nuclear gamma rays from solar flares.
Measurements by a Mars-orbiting spacecraft indicated heating and chemistry changes in the planet’s atmosphere following an extreme solar eruption last year.
High-speed particles cause indentations in the magnetopause to form “throat auroras.”
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.
Comparison of magnetic field structures for 20 coronal mass ejections at eruption versus Earth arrival highlights the importance of tracking structural evolution to refine space weather predictions.
New research shows that solar radiation levels are growing 10% faster than previously believed and that the radiation environment in space will worsen with time.
