ESOs VLT Creates Worlds Largest Virtual TelescopeESO – European Southern Observatory – astronomers in Chile have created the world’s largest virtual optical telescope by using a special technique to combine images from the four most powerful devices as if they were one. “This weekend we managed to finish the process (of merging the images) after almost a year,” says Jean-Philippe Berger, a scientist at the European Southern Observatory which operates the Very Large Telescope array – VLT – in Chile’s high northern desert. For the first time, we made scientific observations through this new instrument, and we can say that it can be used.”

The ESO’s VLT complex in Paranal includes four large optical telescopes, each of which are about 30 metres high and have mirrors eight metres in diameter. The astronomers brought together the signals received by the four telescopes thanks to a technique known as interferometry, which combines the images from the four to achieve a higher resolution image. This creates a virtual mirror which is the equivalent of 130 metres in diameter and, according to Berger, improves the resolution and the ability to “zoom” in on the cosmos.
