"Rare Northern Lights Spectacle Expected in Multiple US States This Week"

Stargazers in Minnesota may have the opportunity to see the aurora borealis, or northern lights, on Thursday evening, as forecasted by the University of Alaska's Geophysical Institute. The viewing area could extend as far south as Missouri, but the timing and visibility will depend on weather conditions. The aurora borealis occurs when electrons from space collide with atoms and molecules in Earth's upper atmosphere, creating neon green waves in the night sky.
