In the sky above ESO's La Silla Observatory, the Southern Cross is visible to the right of the dome of a Danish 1.54-metre telescope. To the lower right of the image, two stars sparkle in the dark sky. From right to left, these are Alpha and Beta Centauri. Alpha Centauri is a multiple star, the nearest star system to Earth. A little closer to Earth than the bright components of Alpha Centauri, and invisible to the naked eye, is Proxima Centauri, the third star belonging to this multiple star system.
