Canadian Prime Minister Stephen Harper on April 6 официально confirmed , that his country will take a direct part in the construction of one of the world's largest land-segmented mirror telescopes. Specifically expressed in part to allocate $ 243.5 million. The construction, which with varying degrees of success already underway in Hawaii last year. To think about the need for funding from the Canadian government went a whole year.
Project TMT telescope with a mirror diameter of 30 meters (surprise) was originally conceived back in the 90s, and it was supposed to be built in California. However, over time the US enthusiasm waned, and acquired new project participants. As a result, now the largest investors are China, Japan, India, and the day before yesterday - Canada.

The mirror will be composed of 492 segments 1, 4 meters, which will be collected in 9 times more light than the largest of the existing ground-based telescopes. Compared with the Hubble images obtained with the new telescope will be about 10-12 times sharper. Laser correction system will help to adjust the telescope mirror to eliminate atmospheric distortions.
However, even if the construction of the telescope will be completed in time for 2024, almost immediately after him in the Chilean desert will have to appear European Extremely Large Telescope a > with a mirror more than 39 meters in diameter. The link you can see the сравнительную chart for various existing and projected telescopes.
A problem in the TMT enough. Hawaii Land Committee approved the project in 2013. Official construction solemnly began October 7, 2014 , and immediately faced with the protests of local residents. Demonstrators from the group Sacred Mauna Kea formed a caravan of cars and protested, albeit peacefully against the "desecration" of the sacred mountain. Гавайцы consider , Mauna Kea that - a symbolic navel island linked with the heavens, where the souls of their ancestors.
Protests since then has not abated - in early March, more than 100 people blocked the access road to the future of the observatory. In April at a construction site already gathered 300 protesters who had to subdue with the help of police.
The Observatory, which seems to be built, designed to study a variety of topics: dark energy, dark matter, tests of the Standard Model, the evolution of galaxies, supermassive black holes, the search for extrasolar planets, and more.
