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.
An international team of scientists has discovered an extreme spike in radiocarbon corresponding to the year 12350 BC during the dusk of the last Ice Age. However, the strength of the event could not be assessed earlier because ...

High above Earth's poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the ...
