Photo detail

Taking a photograph of polar star trails is as easy as mounting your camera on a tripod and aiming it north for a time exposure. At the center of the concentric star trails will be a single bright star — Polaris, our North Star. This shot, looking north toward Rabbit Ears Peak, was taken in August 2001.

Just by coincidence, the Earth’s axis points almost directly at Polaris so that, as Earth spins, Polaris remains nearly motionless throughout the night – the pivot point for the whole sky.
