Rare Northern Lights Set To Glow In U.S. Skies After Mass Ejection From Sun

The sun launching an explosion of electromagnetic energy toward Earth sounds ominous, but when it’s not too much, it makes for some pretty lights.

Our biggest star just blasted out massive Coronal Mass Ejection (CME), sending coronal matter across the solar system. Some of the electromagnetic energy is reaching our atmosphere, and some Americans will be able to see colorful shimmering skies known as the Northern Lights.
