Danish 1.54-metre telescope at night, La Silla Observatory in the Chilean Atacama Desert. The on ground lighting is there to guide cars, which are prohibited from using headlights, to the site. In the sky, to the left, almost hidden behind the telescope, is the faint green glow of Comet 252P/LINEAR and, overhead, the tail of Scorpius curves into the glowing clouds of the Milky Way, keeping close company to Mars and Saturn. Further up the bright galactic band are triple-star systems Alpha and Beta Centauri. At the very top right is the Southern Cross.
