The sun's particles collide with oxygen and nitrogen atoms, resulting in a spectacular light show that's known as aurora borealis in the Northern Hemisphere. "The colors of an aurora come from atoms and molecules being energized by colliding with energetic particles in the upper atmosphere," NASA said.

Night owls and insomniacs alike were sure to witness a grand display of northern lights Tuesday night, with the possibility of more active skies on the horizon.

The aurora can be difficult for the naked eye to see clearly, and can often appear much brighter in pictures than to the naked eye.
