Canadians Plan to Build World's Biggest Telescope 305

Posted by samzenpus from the great-white-north dept.
Jerry Rivers writes "If all goes according to plan, Canada will be home to the world's largest telescope. The international project, which has the support of the U.S. Herzberg Institute of Astrophysics, is still in the funding stages but when finished it will be roughly the size of a football field. Maybe with this they'll finally find the Restaurant at the End of the Universe."

      Canadians have better things to investigate such as:

      You have to build in operating costs for 10-15 years. Operating costs include the maintence staff, data distribution and the salaries of dozens to hundreds of scientists who will use the beast. These can be 2-3 times the construction cost over that long period. This brings total costs into the gigabuck range these days.

        While the rest of your comment is spot on, it's not actually going to be placed in Canada. They're testing possible sites in Hawaii, Mexico and Chile.

        It's a Canadian project with international support. The fact that the U.S. Herzberg Institute of Astrophysics among others are supporting this is because these Canadians have come up with something way beyond the state of the art and demonstrated to the satisfaction of the worlds most knowledgable that they will indeed be able to pull it off.

        In my opinion, this makes the spiteful little jabs that are sprouting up in this discussion are very easy to dismiss.

      While I'm sure other countries will get in on a project of this magnitude, I think both the /. summary and the original article in the Toronto Star are incorrect, I've never heard of a U.S. Herzberg Institute for Astrophysics, and I would be very surprised if one existed, since Gerard Herzberg [nobelprize.org] was a Nobel Prize (chemistry) winning Canadian scientist. Not only there, there is already a National Research Council of Canada Herzberg Institute for Astrophysics [nrc-cnrc.gc.ca] in Victoria. A quick google search also didn't show any "U.S. Herzberg Institute".

    With Hubble getting rather old, I wonder if this will be its successor. Though I can't help but think that a telescope wizzing around in space would be much more useful than one on the ground. The fact that you don't necessarily have to wait 24 hours to take another look at the same bit of the sky surely has to be an advantage.
    • Adaptive optics goes a long way toward compensating for turbulence. The unique value of a space telescope comes from being able to stare at one point of sky, as you point out, and most compellingly from studying wavelengths that don't get through the atmosphere at all.

      Ground telescopes are good for sky surveys, spectroscopy, and economy (which translates to more available observing time).
    • The problem with Hubble is that with advances in image processing, it is now possible to achieve better-than-Hubble results using ground-based telescopes. We already have higher-resolution and more precise satellites covering the UV and IR ranges. Hubble's main (if not only) asset now is being the only long-range visible-light telescope not limited by atmospheric conditions. Unless NASA decides to go ahead with the Hubble upgrades, Hubble will probably come down within the next ~5 years.

Turbulence is one thing, but the UV and IR that is blocked by our atmosphere can be picked up much more easily from space. Personally, I don't see why Hubble can't surpass every other land-based optical telescope on any level except exposure time (due to its smaller optics compared to many

    It's Monday morning, and Toronto resident Steve Dorman shares a quick breakfast of "eggs" (a native food) with his "wife" (an officially state-sanctioned mate), and discusses yesterday's poor showing by the hometown team in "baseball" (a popular local sport). After a kiss on his wife's cheek, he hops on the "subway train" (a mode of subterranean transport) to the office.

                This is life in exotic Canada City, the capital set deep in the heart of the mysterious land known as Canada (pronounced CAN-a-da).

                Like his estimated 35,000 fellow countrymen, Dorman is proud to be a "Canadian." Located 120 miles north of Buffalo, NY, Canada is, according to Dorman, "a nation with a government and laws distinct from those of the United States." It also has a military, a system of taxation, and periodic free elections to select political leader s. It even has its own currency, says Dorman, various denominations of "dollars" that can be exchanged for the many products manufactured in Canada, including Canadian bacon and ice.

                Canada City, Canada's largest community, is located in a place called a "province," a subdivision not unlike the cantons of Switzerland. There are 10 Canadian provinces in all, from Nova Scotia in the east to British Columbia in the west. And, much like America's states, nearly every one of the provinces has its own capital. But make no mistake--there's nothing provincial about these provinces. Canada has both feet planted firmly in the 20th century.

                "In fact, Canadians enjoy advancements such as refrigerated food, zippers and printing," notes Dorman, an "accountant" who goes to work wearing the comfortable trousers, dress shirt and necktie that form a traditional Canadian costume. "Our industries are large and varied, ranging from logging to automobile manufacturing."

                Not too shabby for a nation that just 240 years ago had no electricity.

    One area in which Canada certainly has the U.S. beat is languages. Canadians speak not only English, but also French. In fact, according to Prime Minister (roughly Canada's equivalent of a president) Jean Chr&#233;tien, "French is the primary language in some parts of the country, and English is in others. The national language question has divided our nation terribly, with Quebec even recently threatening to leave the union."
                Canada has produced many prominent people who have gone on to great success in hockey. Among them is Colorado Avalanche goaltender Patrick Roy, who says hockey is the "national sport" of the Canadianers.

                "It's in our blood, it's part of our heritage, and it brings people together," he says of the sport Canada picked up from America in the late '50s. So appreciative is Canada, it even has hockey teams called the "Oilers" and "Jets," named after its favorite American football teams.

                Despite the language problem and other difficulties, at least one Canadianer is optimistic about his country's prospects in the new millennium.

                "Canada will remain free, proud and strong in t he new century," says Dorman, heading off for another day of what in Canada is known as "work." "Our nation will continue to be a beacon to those throughout the world who value liberty, dignity and human rights."

    Aww, isn't that cute? At times like this, there's really only one thing left to say: Oh, Canada!

The less air you have between you and the stars the better. As well, it's absolutely imperative that they operate well away from civilization because light pollution destroys the view. And finally, there's this little thing called automation. You don't really *have* to be there to take pictures anymore.
