AI Insight
In May 2024, Earth experienced its most powerful geomagnetic storm in 20 years during Mother's Day weekend. The storm produced auroras that scientists believe may rank among the strongest displays recorded in the past 500 years. Physicists have traced the origins of these events back to specific solar outbursts that triggered the historic geomagnetic activity.
Why it matters
Understanding the sources of extreme geomagnetic storms is critical for protecting modern infrastructure, including power grids, satellite systems, and communication networks that are vulnerable to solar activity. This analysis helps improve forecasting capabilities for future space weather events that could disrupt technological systems.
Understand the Science
On Mother’s Day weekend in May 2024, Earth experienced its most powerful geomagnetic storm in two decades, spawning auroras—the ribbony bands of light in the nighttime skies in the Northern and Southern hemispheres—that may have been among the strongest displays on record in the past 500 years.
