    India among five nations to build world's largest telescope

    India among five nations to build world's largest telescope - The Hindu

    India along with Japan, the US, China and Canada will start work on the world’s biggest telescope on Hawaii Island that will enable to identify an object as small as coin from a distance of 500 kms.The 30-meter telescope will be established near the summit of the Mauna Kea volcano with a cost of $1.4 billion.The construction is expected to be completed by March 2022. Japan is expected to cover about a quarter of the construction costs.

    To mark the start of construction, 100 astronomers and officials from the five countries are scheduled to attend a ceremony on October 7 at a location 4,012 meters high on Mount Mauna Kea.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 meters in diameter, while the new telescope will be composed of 492 hexagonal mirrors, each measuring 72 cm across.The telescope’s light-condensing capabilities will be 13 times greater than the Subaru telescope’s, enabling the identification of an object as small as a coin from a distance equivalent to 500 kms.

    Astronomer Masanori Ie, a professor at the National Astronomical Observatory of Japan who leads the Japanese team on the project, said the new telescope will broaden the understanding of the cosmos.A telescope with greater light-condensing capabilities can search for stars that are less bright or farther from Earth. The most distant and oldest star observed to date was born some 800 million years after the Big Bang.

    Since the name of the project isn't really given "visibly" in the article - it's the TMT (Thirty Meter Telescope).

    It's planned to be finished in 2020, and will be surpassed in size two years later when ESO's E-ELT 40-meter telescope in Chile is finished. TMT, E-ELT and the 25-meter GMT (also to be finished 2020) will form the triad of extremely large telescopes for the 2020s and 2030s, succeeding and supplanting the current 10-meter triad in Hawaii, the Canaries and South Africa completed in the last decade, and the 8-meter arrays of the 1990s.

    ESO originally planned to build a 100-meter telescope, but scrapped this in favor of E-ELT for budget reasons. E-ELT costs around USD 1.3-1.4 billion, TMT around 1.0-1.2 billion, GMT around 0.7 billion.

    It's notable that TMT is sponsored in a partnership by US and Canadian universities, the Indian government and the Japanese and Chinese National Observatory Associations, in addition to various Canadian R&D trusts, including governmental ones. The US government is not involved in either TMT or GMT. Within the US university landscape, GMT is the main competitor project, with TMT sponsored by Caltech and GMT sponsored by A&M and others.

    This is pretty amazing. This one should give detailed images of the sky from the ground. Although its gonna be hampered by visibility due to the atmosphere of course.

    The Thirty Meter Telescope is a pretty neat project. It has its own web site and (not surprisingly) there's a Wikipedia article about it.

    And besides that, it looks cool. Obviously, somebody thinks it's worth spending $1.3 billion on it.

    India needs to build toilets for its people first. It should be their first priority.

    Why don't you start with yours? After all your country just begged for more money and yet saw fit to spend a billion dollars on high tech weapons.

    Apparently there's local protests against TMT from Hawaiians due to its construction on sacred Mauna Kea.

    Or we could just send all that poop over across the border. Seriously, who called you to this debate to bitch about Indian toilets?

    Janab...we are a very very poor nation and can't afford billions of toilets like you have in Pakistan.

    So we would simply keep using the rivers(flowing towards your area) as open toilet and you can enjoy the rich mineral based water for various purpose including drinking.

    It can be avoided if correct action is taken on trolls with 1 point agenda.

    Then please do.

    Correct action is

    1. ignore the troll. Stay on topic. By "feeding them" you help drag the thread down

    2 report the post to the admin.

    We are(should be) adults here. Act like one.
    Its called Tourist Season. So why can't we shoot them?

    Damn, and I was too busy at work today to respond unlike the retired folks...

    So I am curious as to what the "correct action" being referred to. This question not directed towards Gun Grape.
