Summary
The ESO (European Southern Observatory) has constructed four 8-meter telescopes on the site of the Atacama plateau in Chile (the VLT, or Very large telescope). To increase their power, they will be connected by a system which will combine their individual light to produce the equivalent of a telescope 200 meters in diameter.
The equipment which will accomplish this was named AMBER and was designed by a team which brought together the Grenoble Astrophysics Laboratory, the Côte d'Azur Observatory, the University of Nice, the Max Planck Institute in Bonn, and the Arcetri Observatory in Florence.
