Polaris
Polaris, also known as the North Star, is a multiple-star system located nearly at the North Celestial Pole in the constellation Ursa Minor. Its brightest component, Polaris A, is a classical Cepheid variable supergiant approximately 430 light-years from Earth. The system appears nearly fixed in the sky, making it an important navigational reference.

North Celestial Tree
28/07/2022
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.
