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.
On a special night, if you are lucky, you might catch a faint red glow quietly lighting up Japan's sky, stretching low along the horizon and easy to miss if you are not looking carefully. Subtle and diffuse, it probably appears ...

When NASA scientists first observed a particular radio burst from the sun in August 2025, there was nothing unusual about it. But then the radio burst kept going. Typically, solar radio bursts like these last a few hours ...

When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating ...

Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun's activity across ...
