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 foreground of the picture
is the dome of the
Anglo-Australian Telescope
in central New South Wales Australia. In the middle of the picture is the
South Celestial Pole, easily identified as the point in the sky
at the center of all the star trail arcs.
