The technique of heliospheric imaging could be valuable for future space weather operations.
Controversial observations of long-term changes in the ionosphere appear to be explained by the Sun’s 11-year cycle of activity, not human greenhouse gas emissions.
Short-term funding strategies present serious problems for programs like solar activity studies, where observations and analysis span decades or longer.
Using 8 years of data collected via spacecraft, scientists produce hindcasts of plasma eruptions from the Sun. These will help improve forecasts.
A massive flare and blast of charged particles toward Earth may disrupt satellites and communications and push auroras toward lower latitudes through tomorrow, according to space weather experts.
A new analysis of satellite data could upend conventional wisdom about how solar storms produce their dangerous radiation—not from X-shaped mergers of magnetic field lines but from swirling vortices.
In forecasting the effects of solar storms, understanding how they subside—and not just how they arrive—will be crucial.
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.
In a first-of-its-kind demonstration, scientists provide experimental support for a possible mechanism behind the formation of coronal mass ejections.
New research suggests that Jupiter's magnetic field replenishes its stock of plasma during lulls in solar activity, creating spectacular displays when a solar storm hits.
