INDIA TO BUILD WORLD'S BIGGEST TELESCOPE :

WORLD'S BIGGEST TELESCOPE

India,  along with four other countries,  will start working to build the world's biggest telescope in Hawaii Island.  The 30-metre telescope,  also known as TMT,  will be constructed near the summit of Hawaii the Mauna Kea volcano on Island.  Construction is likely to be completed by 2022.  Besides India,  other nations involved in the project are Japan,  the US,  China and Canada.  Around 100 astronomers and officials from these five countries attended a ceremony in October 2014 in Hawaii to mark the beginning of the construction work.  

India's role 

New Delhi will invest $212 mil-  lion from 2014 to 2023.
The deal for the project was ma terialised during Prime Minister Narendra Modi's recent visit to the US. 

Larger than Subaru 

The telescope will be larger than Japan's Subaru telescope,  one of the world's biggest,  which was also built on the summit of Mauna Kea and started observation in 1999. 

The Subaru Telescope's single main mirror measures 8.2 metres in diameter,  while the new telescope will be composed of 492 hexagonal mirrors,  each measuring 72 cm across.  In other words,  the telescope's mirror stretching almost 100 feet in diameter is nearly the length of a Boeing 737's wingspan
