World’s largest optical telescope created


The Very Large Telescope (VLT) in Chile

Astronomers have created the world’s largest virtual optical telescope by linking four telescopes of the Very Large Telescope (VLT) in Chile.

The linked telescopes are located at the Cerra Paranal mountain and together they form a virtual mirror of 130 meters in diameter.

The telescopes are linked together through a process called interferometry and will give scientists a more detailed look at the universe.

The key part of an optical telescope is a mirror. When objects are observed with separate telescopes, light is reflected off individual mirrors first.

In the next step, the interferometer directs the light underground into tunnels. Then the light is combined into one single beam.

The final image astronomers get has great zoom as if a single telescope with a gigantic mirror has produced it.

This makes the VLT the biggest ground-based optical telescope on earth.

The interferometer also greatly improves the telescope’s spatial resolution and zooming capabilities.

“[This event is] milestone in our quest for uncovering secrets of the universe” the state-funded BBC quoted head of instrumentation at Paranal Frederic Gonte as saying.

“From now on we’ll be able to
