Starfield. Starfield containing the Plough and the Pole Star above a mountain. The Plough (upper left) is a group of stars in the constellation Ursa Major. The lower two stars here point towards the Pole Star (Polaris, or Alpha Ursae Minoris) in the constellation Ursa Minor (upper right). The Pole Star is the closest bright star to the north celestial pole, and all other stars appear to revolve around it in the northern hemisphere.
