De weg naar de Melkweg op La Silla
In deze afbeelding strekt ons eigen sterrenstelsel, de Melkweg, zich uit boven de Chileense Andes. Op de voorgrond ligt de weg naar ESO's La Silla Observatory. Het observatorium staat vol met state-of-the-art telescopen die naar de Melkweg kijken en verder.
Op de foto zijn verschillende telescopen te zien. De ESO 3.6-metre telescope staat op de centrale platform. De telescoop bevat HARPS, de High Accuracy Radial velocity Planet Searcher. Dat is de beste exoplanetenspeurder op aarde. Naast de grote koepel staat een kleinere die ooit de Coudé Auxiliary Telescope (CAT) en de Coudé Echelle Spectrograph huisvestte. Beide instrumenten zijn nu buiten gebruik. Onderaan het platform staat TAROT, de Franse Rapid Action Telescope for Transient Objects (TAROT). TAROT speurt naar hoog-energetische verschijnselen zoals gammaflitsen. Die worden ook onderzocht door de Zwitserse 1.2-metre Leonhard Euler Telescope in de koepel aan de linkerkant, maar die zoekt eigenlijk meer naar exoplaneten.
Verder naar rechts is SEST zichtbaar, de Swedish–ESO Submillimetre Telescope. SEST is buiten gebruik genomen in 2003 en vervangen door de Atacama Pathfinder EXperiment telescope (APEX) op het Chajnantor Plateau. Een kaart met alle faciliteiten van La Sillia staat hier.
De grote hoeveelheid aan instrumenten op La Silla laat zien dat deze plek veel gebruikt wordt voor sterrenkundige waarnemingen. La Silla ligt hoog en ver van helder verlichte steden (links is het (gedramatiseerde) effect van de zwakke remlichten van een auto zichtbaar).
