在这幅精心设计的夜空中，一棵古树似乎伸向了地球的北天极。在中国新疆西北部的义乌沙漠白杨林，用固定在三脚架上的相机记录了连续曝光的延时构图。优雅的星迹弧线反映了地球每天绕地轴自转。通过延伸，旋转轴指向夜空中同心圆的中心。明亮的北极星被称为北极星，是北半球夜空摄影师和天体导航员的朋友。这是因为北极星非常靠近天空中的北天极。当然，它可以在一张旋转行星的明信片上的一根伸展的光秃秃的树枝的顶端找到。

An ancient tree seems to reach out and touch Earth's North Celestial Pole in this well-planned night skyscape. Consecutive exposures for the timelapse composition were recorded with a camera fixed to a tripod in the Yiwu Desert Poplar Forests in northwest Xinjiang, China. The graceful star trail arcs reflect Earth's daily rotation around its axis. By extension, the axis of rotation leads to the center of the concentric arcs in the night sky. Known as the North Star, bright star Polaris is a friend to northern hemisphere night sky photographers and celestial navigators alike. That's because Polaris lies very close to the North Celestial Pole on the sky. Of course it can be found at the tip of an outstretched barren branch in a postcard from a rotating planet.
