Largest optical telescope created
« on: February 06, 2012, 03:22:01 PM »
Astronomers have created the world's largest virtual optical telescope linking four telescopes in Chile, so that they operate as a single device. The telescopes of the Very Large Telescope (VLT) at the Paranal observatory form a virtual mirror of 130 metres in diameter.

Linking all four units of the VLT will give scientists a much more detailed look at the universe than previous experiments using just two or three telescopes to create a virtual mirror. The process that links separate telescopes together is known as interferometry.

In this mode, the VLT becomes the biggest ground-based optical telescope on earth. Besides creating a gigantic virtual mirror, interferometry also greatly improves the telescope's spatial resolution and zooming capabilities.

The VLT is one of several telescopes in the Atacama Desert, set up by the European Southern Observatory (Eso) which is an international research organization headquartered in Munich, Germany.
