Increased solar activity causes auroras that dance around Earth’s poles, known as the northern lights, or aurora borealis, and southern lights, or aurora australis. When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored lights in the sky.

The northern lights were visible Tuesday night across the Chicago area, illuminating the sky with brightly colorful displays due to severe solar storms.

Northern Lights may dazzle again tonight as a severe geomagnetic storm reaches peak intensity across regions. Follow live.
