The Very Large Telescope (VLT) is an astronomical facility operated since 1998 by the European Southern Observatory, located on Cerro Paranal in the Atacama Desert of northern Chile. It consists of four individual telescopes, each equipped with a primary mirror that measures 8.2 meters in diameter.
Comparison of nominal sizes of apertures of the above extremely large telescopes and some notable optical telescopes. An extremely large telescope (ELT) is an astronomical observatory featuring an optical telescope with an aperture for its primary mirror from 20 metres up to 100 metres across, [1] [2] when discussing reflecting telescopes of optical wavelengths including ultraviolet (UV ...
The Giant Magellan Telescope (GMT) is a ground-based, extremely large telescope currently under construction at Las Campanas Observatory in Chile's Atacama Desert.With a primary mirror diameter of 25.4 meters, it is expected to be the largest Gregorian telescope ever built, observing in optical and mid-infrared wavelengths (320–25,000 nm).

The secondary mirror is expected to be the largest convex mirror in any operating telescope, until surpassed by the Extremely Large Telescope's 4.2-meter secondary in about 2028. The second and third mirrors reduce the primary mirror's light-collecting area to 35 square meters (376.7 sq ft), equivalent to a 6.68-meter-diameter (21.9 ft ...
An ESO project is the Extremely Large Telescope (ELT), a 40-metre-class telescope based on a five-mirror design and the formerly planned Overwhelmingly Large Telescope. The ELT will be the largest visible and near-infrared telescope in the world. ESO began its design in early 2006, and aimed to begin construction in 2012. [22]
Scientists are souping up a telescope in Chile in order to aid in the search for a potentially suitable new home for humankind. 'Very Large' telescope gets massive upgrade to hunt for habitable ...
The Very Large Telescope (VLT), the largest telescope on Paranal, is composed of four separate 8.2 m (320 in) telescopes. In addition, the four main telescopes can be used simultaneously for extra light gathering capacity, and for interferometry. Four auxiliary telescopes of 1.8 m (71 in) each are also part of the VLTI to make it available when ...
Cerro Armazones is a mountain located in the Sierra Vicuña Mackenna of the Chilean Coast Range of the Andes, approximately 130 km (81 mi) southeast of Antofagasta in the Antofagasta Region, Chile. The mountain is situated in an ideal location for optical astronomy due to its 89% cloudless nights annually. [ 1 ]
