India has joined an elite group of countries including the USA, China and Japan, to build the largest telescope in the world that is being built at Mount Mauna Kea on an island in Hawaii. The next-gen 30 meter telescope is expected to give a major boost to the field of astrophysics and understanding various facets of the Universe. The agreement was signed in Delhi in the presence of the Union Science and Technology Minister and officials of the Department of Science and Technology and Atomic Energy as well as representatives of the Embassies of China, US and Japan. Canada is the fifth country expected to sign the agreement soon. India will contribute 30 percent of the amount to the total pool of constructing infrastructure facilities, while 70 percent will be used to provide sensors and actuators.
