A stunning northern lights display filled the Seattle sky with bright green overnight.

The National Weather Service called it "probably the best #aurora 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.

It's more common to see this kind of epic display in higher latitudes, such as in Alaska and Canada.
