Space weather as a research area investigates the variable conditions in space driven primarily by solar activity and their impact on the heliosphere, near-Earth environment, and technological systems. It encompasses the study of the solar magnetic field, flares, coronal mass ejections, high-speed solar wind streams, and energetic particles, and how these phenomena interact with planetary magnetospheres, ionospheres, and upper atmospheres. Research integrates observations, theory, and physics-based modeling to understand and predict geomagnetic storms, radiation belt dynamics, ionospheric disturbances, and associated hazards to satellites, communication and navigation systems, power grids, and human spaceflight.
Researchers have created an improved traffic light system for predicting geomagnetic storms. They are now testing how well these algorithms can prepare us for incoming space storms that can wreak havoc by knocking out satellites ...

During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae ...
Encircling Earth are the Van Allen radiation belts—vast, doughnut-shaped rings of highly energetic charged particles, mostly originating from the sun, that are trapped by our planet's magnetic field, or magnetosphere. The ...
