When the Sun erupts three times in 48 hours, Earth feels it ☀️ In November 2025, our star unleashed a rapid sequence of solar outbursts that swept across space and triggered a severe geomagnetic storm here on Earth. Scientists detected radio blackouts lasting up to an hour, rare high-energy particles breaking through our magnetic shield, and stunning auroras far from the poles. Even so, the storm caused minimal disruption on the ground, and our missions - from low-Earth orbit to deep space - recorded valuable radiation data to help us understand and prepare for future events. From Swarm’s magnetic measurements to Solar Orbiter’s close-up view of the flare, each spacecraft added a piece to the puzzle. As we look ahead to missions like Vigil, which will watch the Sun from a new vantage point, we’re building the tools to detect space-weather hazards earlier and protect both satellites and future astronauts. Solar storms are powerful - but they’re also an opportunity to learn. 📹 @euro...
