Thirty Metre Telescope Likely To Be Installed At Hanle In Ladakh.

The Thirty Meter Telescope (TMT) is a proposed astronomical observatory with an extremely large telescope (ELT) that has become the source of controversy over its planned location on Mauna Kea on the island of Hawaii in the US state of Hawaii. .

At the heart of the telescope will be a mirror made up of 492 individual segments. Precisely aligned, these segments will work together as a single reflective surface with a diameter of 30 metres TMT will be three times as wide, with nine times more area, than the largest currently existing visible-light telescope in the world named Hubble Space Telescope..Compared to the Hubble Space Telescope, which is widely regarded as the most revolutionary astronomical instrument of the generation, the new project, known as the Thirty Meter Telescope (TMT), will best the Hubble in many categories.At 30 meters across, the TMT will have 144 times the light collecting area of the Hubble and have spatial resolution at near-infrared and wavelengths 10 times that of Hubble's.

"The Hubble Space Telescope has definitely set a milestone in high-resolution imaging. We've all seen beautiful pictures of distant galaxies," said Richard Ellis, a professor of astronomy at Caltech.

"TMT, with adaptive optics, give us a much finer quality of detail than Hubble Space Telescope," he said.

The TMT project is an international partnership between CalTech, Universities of California, Canada, Japan, China and India. The telescope was initially supposed to come up in Hawaii but had to be stopped due to local protests. Hanle in Ladakh was then proposed as one of the alternative sites, the others being in Chile.

The TMT- India project will propel India into a special league of deep space research. The main Indian institutes working on this unique project are Aryabhatta Research Institute for Observational Sciences (ARIES), the Indian Institute of Astrophysics (IIA), and the Inter-University Center for Astronomy and Astrophysics (IUCAA).
