   Explanation: [5]Graceful star trail arcs reflect planet Earth's daily
   rotation in this colorful night skyscape. To create the timelapse
   composite, on May 12 consecutive exposures were recorded with a camera
   fixed to a tripod on the shores of the Ashokan Reservoir, in the
   Catskills region of New York, USA. North star [6]Polaris is near the
   center of the star trail arcs. The broad trail of a waxing crescent
   Moon is on the left, casting a strong reflection across the reservoir
   waters. With [7]intense solar activity driving recent [8]geomagnetic
   storms, the colorful aurora borealis or northern lights, rare to the
   region, shine under Polaris and the north celestial pole.
