Explanation: If you climbed this
magnificent tree, it looks like you could reach out and touch the North
Celestial Pole at the center of all the star trail arcs. The well-composed
image was recorded over a period of nearly 2 hours as a series of 30 second long,
consecutive exposures on the night of October 5. The exposures were made with a
digital camera fixed to a tripod near Almaden de la Plata, province of Seville,
in southern Spain, planet Earth. Of course, the graceful star trails reflect
the 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. Convenient for
northern hemisphere night sky photographers and celestial navigators alike, the
bright star Polaris is very close to the North Celestial Pole and so makes the
short bright trail in the central gap between the leafy branches.
