Worlds biggest telescope to be built in Hawaii

Construction of world's biggest telescope begins

The construction of ambitious next-generation Thirty Meter Telescope, to be built at an estimated cost of USD 1.47 billion by an international consortium consisting of institutions from India, the US, Canada, Japan and China, has begun this week in Hawaii.

The gigantic telescope, scheduled to be ready by 2020, will provide astronomers with unparalleled power to observe the intricacies of the universe from the comfort of Earth.

The project is an international consortium consisting of institutions from the USA, Canada, Japan, India and China.

The TMT will enable scientists to study fainter objects far away from us in the Universe, which will give information about early stages of the evolution of the Universe.

It will also give finer details of not-so-far-away objects such as undiscovered planets and other objects in the Solar System and planets around other stars.

The TMT will be one of the largest optical-infrared telescopes to come up in the next decade. Its 30 meter diameter primary mirror will consist of 492 segments of 1.44 meter diameter each.

These mirror segments will be cleverly positioned relative to each other through sophisticated sensors, actuators and control systems, so that the entire assembly behaves like a single monolithic mirror.
