Circumpolar Star Trails

Star trails arc around the North Celestial Pole above an observatory on Tenerife in the Canary Islands. As Earth rotates, the stars appear to move in concentric circles around Polaris, the North Star, which is positioned behind the telescope dome. This image is a composite of many exposures, showing the paths of the stars over time. It demonstrates Earth's spin on its axis.
