    Construction of a massive telescope triple the size of the world's largest current optical telescopes is set to begin on Hawaii's Mauna Kea volcano this year.
    The Thirty-Meter Telescope (TMT), which will consist of interlocking, segmented mirrors with a diameter totaling 30 meters (98 feet), has raised 83 percent of its funding, and builders could break ground by this summer, the project's leaderssay.
    "We're really ready to go with this telescope," Dr. Michael Bolte, associate director for the TMT project, said last month at a meeting of the American Astronomical Association in Washington, D.C. [Thirty Meter Telescope: Hawaii's Giant Space Eye (Gallery)]

    I'm not an astronomer in any regard and yet this stuff always gets me so excited. I look forward to the JWST launch more than Christmas.

    From Article:
    "The TMT will have nine times the light-collecting power of Keck, and 12 times sharper images than the Hubble Space Telescope using the tools of adaptive optics,..."

    Very nice, but what are they hoping to find with it?

    They could see other planets that are revolving around other suns thousands of light years away for one thing.

    They could see farther back into the beginning of our universe, if there is anything farther than we can already see.

    Maybe, but it is on earth, and the earth rotates. One of the beauty things about the space telescopes was they could be parked pointing at one part of the sky for a long time.
    That was how the Hubble Deep Space pictures were taken.
    I don't know if the higher resolution and light gathering ability of this scope compensates for the ability to aim it and leave it for a while, which is why I wonder what they intend to use it to look for.

    You have a point, perhaps there's other astronomical events that they will be using it for.

    I hope so. It is a nice looking scope.

    Agreed, but earths rotation & even its orbit is not difficult to compensate for. We can easily fix it on a single point & correct for the rotation of earth. thus pick up viewing night after night in the same spot.

    Bigger problem I see is earths atmosphere itself. So much dust & particles floating about makes it more difficult to see than with a space bound telescope.

    I agree, it should of been built in space. Would of been a great addition to our great observatories in the sky.

    Still, quite a massive telescope that I hope furthers out understanding of the universe.
