Star trails over cows in a field. Time-exposure image of stars forming light trails in the sky over cows in a field on a moonlit night near Telheiro, in the Alqueva Dark Sky Reserve, Portugal. Star trails (here circling the northern celestial pole) are created on long-exposure images by the Earth's rotation on its axis. Photographed in 2015. | |
