Stunning northern lights display brightens Seattle sky

The National Weather Service shot this image of the northern lights over Seattle on May 8, 2016.

The National Weather Service shot video Sunday morning of a stunning northern lights display that lit up the sky in a green auroral glow.

The National Weather Service tweeted photos of the light show calling it "probably the best #aurora light display we've seen in a decade here in #Seattle. Simply amazing."

In the Northern Hemisphere, the aurora borealis, also called the "northern lights," occurs when particles from space interact with electrically charged particles in the Earth's magnetic field.
The particles in space, fueled by energy from the sun, collide with particles in the Earth's magnetic field and emit light, which in most cases is viewed as the color green in the sky.
