Stars appear to rotate around the southern celestial pole at the European Southern Observatory’s La Silla Observatory in northern Chile. The fuzziness in the trails on the right is caused by the Magellanic Clouds, two small galaxies neighboring the Milky Way. The dome at lower left houses ESO’s 3.6-metre telescope and HARPS (High Accuracy Radial velocity Planet Searcher). The rectangular building at lower right contains the 0.25-meter TAROT telescope.
