Explanation:
As the 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 of the picture is the
North Celestial Pole (NCP), easily identified as
the point in the sky
at the center of all the star trail arcs.
The very short bright trail near the NCP was made by the
star Polaris, commonly
known as
the North Star.
