Comet dust rained down on planet Earth last August, streaking through dark skies in the annual Perseid meteor shower.

Star Trails in Southern Skies
26.09.1995

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.

The Case of the Missing Aurora
