Star Trails in Northern Skies Credit and Copyright:

As Earth spins on its axis, the sky seems to rotate around us. This motion produces the beautiful concentric arcs traced out by the stars in this time exposure of the night sky. In the middle is the North Celestial Pole, the center of all the star trail arcs. The short, bright trail near the pole was made by Polaris, the North Star.
