Canadians Plan to Build World's Biggest Telescope 305
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."

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.

Perky 'Canada' Has Own Government, Law (Score:4, Funny)
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.
Canada City
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 Chrétien, "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!

I happen to have the good fortune to work on The Magdalena Ridge Observatory [nmt.edu] Interferometer. We're beginning construction very soon, and it is the successor to the COAST [cam.ac.uk] telescope in Cambridge.
The advantage of interferometers is that we can have the effective aperture of 400m (so obtaining high angular resolution) without the problem of building and maintaining a distortion-free enormous mirror. Of course, we don't get the sensitivity, but we do get the resolution.
Incidentally, COAST (Cambridge Optical Aperture Synthesis Telsecope), which was built in the late '80s has a better angular resolution than Hubble (although we do have a lot of atmosphere in the way!), and has managed to sucessfully image detail on the surface of stars.

1. I sure hope you said astronomical, rather than astrological, or the astronomers will shoot you when they find out.
2. Places that are hostile to people are ideal for telescopes. Keck for instance, is at nearly 14,000 feet above sea level. If you want to breathe, generally you do it from a tank. 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. The best visual telescope in the world is the one in the most hostile environment of all: in orbit. The only possible way to make it work is by automation.
