Northern Lights in Alaska

From U.S. Department of the Interior:

Longer nights in Alaska mean more chances to see the northern lights. Above the frigid landscape of Denali National Park & Preserve, the dark sky comes alight with bright waves of color caused by massive bursts of solar wind and magnetic fields interacting with elements in the Earth's atmosphere.
