Researchers challenge long-held theory on how Earth withstands extreme space weather

Earth's shield against extreme space weather may work differently than scientists assumed — and the gap in understanding has real stakes for satellites, GPS, and power grids.

Theory Briefing
- Researchers are challenging the long-held theory explaining how Earth resists severe geomagnetic disturbances from space weather events.
- Severe geomagnetic storms can disrupt satellites, GPS, radio communications, aviation, and power infrastructure — making the theoretical gap practically urgent.
- The existing model has guided space weather forecasting, so overturning it could reshape how scientists predict and prepare for solar threats.
- The challenge suggests Earth's magnetic defenses operate through a different mechanism than the one textbooks have described for decades.
