Original Message The European Southern Observatory Very Large Telescope array at Paranal, Chile. An array of four "Unit Telescopes", each with a main mirror of 8.2 metres in diameter. With one such telescope, images of celestial objects as faint as magnitude 30 have been obtained in a one-hour exposure. This corresponds to seeing objects that are four billion times fainter than those seen with the naked eye.
The VLT also has four additional 1.8-metre moveable Auxiliary Telescopes. One of the most exciting features of the VLT is the option to use it as a giant optical interferometer (VLT Interferometer or VLTI). This is done by combining the light from several of either the Unit Telescopes or Auxiliary Telescopes. In this interferometric mode, the telescope has a vision as sharp as that of a telescope the size of the separation between the most distant mirrors. For the VLTI with the Auxiliary Telescopes, this is up to 200 metres....

World's Largest Telescope Project Gets Green Light
"The European Extremely Large Telescope (E-ELT) will be a 129-foot (39-meter) segmented-mirror telescope sited atop a mountain called Cerro Armazones in northern Chile, close to ESO’s Paranal Observatory. It will be many times more sensitive than any other instrument of its kind, researchers said..."
