World's largest solar telescope coming up in Ladakh
India is expected to start building the world's largest solar telescope on the icy heights of Ladakh to study the sun's atmosphere and understand the formation of sun-spots and their decay process.
The Rs 300-crore project is expected to come up at either Hanle or Merak, which is very near to the Ladakh's Pangong lake along the Line of Actual Control with China.
Currently, the world's largest solar telescope is the McMath-Pierce Solar Telescope with an aperture size of 1.6 metres in Kitt Peak National Observatory at Arizona in the US.
"Fabrication of the National Large Solar Telescope is expected to begin in late 2013," Siraj Hasan, Principal Investigator for the project, told reporters on the sidelines of the 100th Indian Science Congress here.
The telescope, with an aperture size of two meters, is planned to be completed by 2017 and will be the largest such facility in the world at least till 2020 when US is expected to commission its four-meter telescope at Hawaii.
The main objective of the facility would be to study the formation and decay of sun spots, their subsurface structure and Why do they have a penumbra and how is it formed, Hasan said.
Most of the back-end instruments of the telescope would be made in-house and the instrument for night time observations would be developed in collaboration with Hamburg Observatory in Germany.
NLST is expected to be a unique research tool which is likely to attract several talented solar astronomers to the country and provide a superior platform for performing high quality solar research, Hasan said.
Bangalore-based Indian Institute of Astrophysics is the nodal agency for the project, which also has participation from Indian Space Research Organisation, Aryabhatta Research Institute of Observational Sciences, Tata Institute of Fundamental Research, IUCAA, IISc and IISER.

India to partner in advance telescope project
India plans to chip in Rs 760 crore towards building a mega telescope, which will be used by astronomers from all over the world to find answers to many underlying mysteries of the universe.
Known as Thirty Meter Telescope (TMT), it will be the world's most advanced ground-based observatory, to be located below the summit of Mauna Kea peak in Hawaii. If funds flow in time, the telescope may see the first light by 2021.
India, the USA, Canada, Japan and China are sharing the cost for this Rs 7,600 crore ($1.4 billion) project, which will be open to the international community. TMT was approved in the 12th plan, K Kasturirangan, member Planning Commission, told Deccan Herald. The union cabinet is yet to approve the financial package.
While India and China each were contributing close to 10 per cent of the project cost, the contribution from the US, China and Japan is upwards of 20 per cent each.
We plan to begin the construction in 2014 and want to ink formal agreements with Indian government this year, Edward Stone, a professor of physics at California Institute of Technology and vice chair of TMT board said here after the TMT board meeting.
Close to 70 per cent of Indian contribution will be in kind. This means India will supply more than 3,000 edge sensors, 492 segment support assembly and 1,476 actuators, said Sirajul Hasan, former director of Indian Institute of Astrophysics (IIA), Bangalore, the nodal Indian institute for the TMT project.
The primary mirror at the core of the telescope is a gigantic 30 metres in size. Since it is difficult to make and transport a 30-mt single piece mirror, telescope designers split the mirror into 492 hexagonal segments, each 1.44 metres in size. Combined together, they will act as a 30-mt mirror for the telescope.
India will make segments 115 to 150, Hasan said. A Pondicherry-based firm General Optics Asia and Larsen and Toubro have been roped in to design mirror segments and other components.

No one paid attaintion here how much these news links are fucked up.
They are putting 2 figures for China in one line.
