European Southern Observatory
The European Southern Observatory (ESO) is an intergovernmental organization founded in 1962 and supported by 16 member states and host country Chile. ESO designs, builds, and operates some of the world's most advanced ground-based astronomical observatories—such as La Silla, Paranal (home to the Very Large Telescope and other survey instruments), and the Atacama Large Millimeter/submillimeter Array (ALMA)—and is currently constructing the Extremely Large Telescope (ELT).

Yepun
27/09/2000
Pictured above on September 3rd, the enclosure for the 8.2 meter telescope christened Yepun glints dramatically in the light of the setting sun. Later that evening, under dark skies at Paranal Observatory, Chile, astronomers and engineers successfully captured Yepun's first light images, making Yepun the fourth and final unit of the European Southern Observatory's Very Large Telescope (VLT) array to reach this milestone. Ultimately, the light from the three other 8.2 meter unit telescopes (Antu, Kueyen, and Melipal) will be combined with Yepun's to achieve an effective aperture of 16.4 meters -- creating the world's largest optical telescope. But the next major step will be to combine beams from two of the telescopes creating an interferometer. The upper part of the mostly subterranean interferometer lab is the building in front of the telescope enclosure. The VLT unit telescope names have been taken from the Mapuche language. Originally thought to refer to the bright star Sirius, the word Yepun is now believed by linguists to mean Venus or evening star.
