October - Spinning stars over La Silla Observatory

This long-exposure shot, taken from ESO’s La Silla Observatory in Chile, shows the luminous trails left by stars in the night sky as the Earth rotates, leading to their apparent motion. The stars appear to spin around a point in the sky just to the right of the centre of the picture — the celestial south pole. In the foreground are the ExTrA and BlackGEM telescopes.
