It's Been a Year Since the Most Powerful Solar Storm in Decades. What Did We Learn?
One year ago, our star erupted with almost apocalyptic force—unleashing the most violent solar assault in two decades. Dubbed the Gannon storm, it wasn't just another solar flare. Multiple coronal mass ejections collided and merged into a single devastating megastorm that slammed into Earth's protective shield. As our magnetosphere buckled the night skies exploded with spectacular auroral displays. The event even reached Mars with images from Curiosity sprinkled with streaks from charged particles.
