The Northern Lights put on a stunning display above Alaska's Glacier Bay National Park on March 18.
The natural light show was captured by photographer Wesley Kocurek.
Kocurek said he had never seen anything like it before.
The Northern Lights, or Aurora Borealis, are a natural light display in the Earth's sky.
They are caused by collisions between electrically charged particles from the sun and particles in the Earth's atmosphere.
The lights are most commonly seen in the Arctic and Antarctic regions.
Glacier Bay National Park is a popular destination for tourists and nature enthusiasts.
