Is the Canadian Arctic the Future of Astronomy?
sciencehabit writes "Frigid temperatures, dry air, and endless nights should, in theory, make the polar regions top spots for ground-based optical astronomy. So far, Antarctica has been getting all the action, with a handful of optical telescopes peering into the sky from the icy continent. But a new study indicates that the Canadian high Arctic is also a good spot for ground-based optical astronomy. In fact, the great white north offers some practical advantages over the Antarctic."
To begin with, it'd probably be easier to get there.
Disclaimer: I've never so much as been to Canada so I don't know what it's like in the polar region there, but I'd imagine that the lack of a huge southwards plane / boat voyage would be an immediate bonus over Antarctica.
Probably be easier to get internet and other communication up there as well.
One thing I know, and that is that I am ignorant...
there should be more than a few points that are up high there as well.
I prefer the "u" in honour as it seems to be missing these days.
Telescopes generate huges amount of data. Fiber to the south pole must not be cheap.

Or use a site at the equator. Its useless arguing between north and south poles. Each can only see half the sky.

Secondly, I don't see why "endless nights" are so much of an advantage, since that just means your telescope is fairly useless during the "endless days" of the summer months.

....there may be a serious problem caused by permafrost thaw, the coming years, due to climate change. In other words: what are you going to build upon ?

Maybe initial analysis could be done on site and data dumped to storage media to be couriered elsewhere every few days?
Anything with higher priority could be transmitted by satellite uplink, presuming the cost of such bandwidth is not prohibitive.
I suspect the issues would occur when heat from the buildings affect the permafrost they are immediately sitting on.
For optical astronomy (that is in visible, near-infrared light) the long winter nights are good for observing objects continuously 24/24 as long as non-cloudy sky permits.
Of course the converse occurs in summer when darkness doesn't exist for months.
Polar auroras are also a nuisance.
This is a silly suggestion. The future of astronomy is not in Canada but in space...
The arctic has a lot of air traffic. Would that cause any light pollution issues?

Aurora occur in rings centered on the magnetic poles, not at the magnetic poles themselves. As activity intensifies, the radius of these rings increases, in parallel with lines of geomagnetic latitude, but even in periods of very low solar activity their radius never goes to near zero -- meaning, there are few aurora near the magnetic poles themselves.
In addition to the scientific benefits, scientists can also finally put to rest the stereotype that nerds are weaklings. Since they will have nothing else to do during downtime, they can prove how manly they are through engaging in polar bear combat and then blogging about how to prepare and eat polar bear steaks. Nothing manlier.

And I am sure the astronomers would love having to wear oxygen masks the whole time they are in the observatory. +1 for continuous airplane air from positive pressure living quarters. You forget that the air is unlivably thin up there.
The high altitude telescopes at Chile takes care of a lot of southern sky.
In the north there is HANLE IAO in the Himalayan deset at 4300m altitude.
So I guess, antarctic telescope would take care of further south, while the arctic will take care of northwards.

Federal Express don't go to the south-pole, only the NY Air National Guard.
"and endless nights" ...for maybe 1/4 of the year.
For half the year its about 50% and then 1/4 of the year it's endless daytime.
South-pole? Were we not talking about the arctic?
If the Arctic ocean is going to ice free by 2050, how can the air be "dry" in that region of the world? Isn't the air humidified by the ocean?
I mean, I guess that temperatures are lower on Antarctica (because the land keeps the warming currents far from the interior?). The ice never melts (hasn't for millions of years!) and the air stays drier (i guess though even ice sublimates some water vapor). Still it should be a lot drier right?
Have gnu, will travel.
Um wouldn't one of the obvious problems be the build up of ice and snow and the necessity of its removal constantly?

Day 215: "Trapped in Telescope again. Polar bears are circling like sharks. Loyd and Weber are gone.I don't know how much longer I can hold out."
Day 216: "Discovered another exoplanet. Tentatively named it Ursa Polaris Pallas Meas Lambe 12."
Day 217: "Another supply air drop came today. Bears ate it. Played with the rest. They are just taunting me now."
Thread following fail. GP was refering to it's own GP's mention of South Pole.
It's hard to take a clear picture of a far away galaxy that requires as little cloud and atmospheric interference as possible, and for motors to slowly track the far away object with the slow motion of earth through space.
Putting a telescope on the equator with it's faster motion and hectic atmospheric conditions is the equivalent of trying to take a portrait shot of a race car driver while speeding around a track in fog. Sure, it can be done, but it will never be of the same quality for money spent. This is why space based telescopes are needed for the clearest pictures of the furthest away objects.
Even if it did work, you still don't get the entire sky just by going to the equator. Near the horizon, you have severely bending light, and the accumulation of not just one cloud, but lines of clouds for miles. There is one single location solution for ground based telescopes.

South has a view of the entire center of milk way, north pole does note. So for "short range" (within the galaxy) south pole is better. For "long range" (outside the galaxy), north pole is better.
I've always been surprised that North Korea doesn't exploit its situation of having the darkest skies in Asia for the purpose of optical astronomy.
