I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The Very Large Telescope (VLT) is an astronomical facility operated by the European Southern Observatory, located on Cerro Paranal in the Atacama Desert of northern Chile. It consists of four individual optical telescopes, each equipped with a primary mirror measuring 8.2 metres (27 feet) in diameter, which are generally used separately but can be combined to achieve a very high angular resolution. The VLT array is complemented by four movable auxiliary telescopes with 1.8-metre (5.9-feet) apertures, and the VLT Survey Telescope (at right in the photograph). This photograph, taken at sunset in 2015, shows the VLT and its associated telescopes and supporting buildings.Photograph credit: ESO / Gerhard Hüdepohl; retouched by Huntster
