The Narrative Fallacy writes "Live Science reports that astronomers in search of the perfect site to take pictures of the heavens have combined data from satellites, ground stations and climate models in a study to assess the many factors that affect image quality — cloud cover, temperature, sky-brightness, water vapor, wind speeds and atmospheric turbulence. They have pinpointed the coldest, driest, calmest place on earth, known simply as Ridge A, 13,297 feet high on the Antarctic Plateau. 'It's so calm that there's almost no wind or weather there at all,' says study leader Will Saunders, of the Anglo-Australian Observatory. 'The astronomical images taken at Ridge A should be at least three times sharper than at the best sites currently used by astronomers.' Located within the Australian Antarctic Territory, the site is 89 miles from the PLATO (PLATeau Observatory) international robotic observatory. The new site would be superior to the best existing observatories on high mountain tops in Hawaii and Chile, Saunders says. 'Because the sky there is so much darker and drier, it means that a modestly-sized telescope would be as powerful as the largest telescopes anywhere else on earth.'"

    but I still think the best spot for observational astronomy has to be the far side of the Moon. You've got several thousand miles of light and EM shielding, and a good couple weeks' seeing a month when the Sun goes down. Once the 'scopes cool off, there's no warping. What's not to love?

      But the downside is that it costs like $100 billion to build and man[1] one there. I doubt the Antarctic place would approach one billion.

      • And the antarcitc site comes with its' own problems, Since it isn't windy, any man-made smog will stay there. You're going to need to burn fuel for the generators, heating, transport, etc., and in cold temperatures you're going to get the water vapor in the exhaust crystalizing, forming ground-level fog. Since it's so calm, it'll just accumulate, then condense on the cold optics. Have fun seeing when your mirror's frosted over with an inch of rime.

          Presumably you put the generator a sufficient distance away to minimize any disturbance to the optics, or to seeing quality. The area gets almost no precipitation and probably no animal life, so anything you lay on the ground will remain undisturbed. In this sense it seems like an ideal place to run an automated telescope, if you can get past the somewhat difficult access issue.

          Regarding the "condensing on the optics" problem, astronomers have hundreds of years of experience dealing with this issue. The simplest approach is to slightly warm the optics using resistive heaters. As long as the optics are slightly warmer than the surroundings, any water in the air will condense somewhere else. You don't want too much heating, since then you form convective air currents above the mirror that harm the seeing conditions. However with some reasonably accurate temperature sensors and a feedback controller, the condensation problem is straightforward to solve.

      The problem is getting the data back to Earth. I would assume that it would be an un-staffed observatory, in which case, you'd need to do one of the following:
      • send up a courier to swap out SD cards every few weeks.
      • set up a network connecting the station with a transmitter which has line-of-site to the Earth.
      • put a couple of satellites in orbit which are in line-of-sight to the far side of the moon, so that the data could be relayed back to Earth.

      Oh, give me a home where the penguins roam
      And the frigid astronomers play
      Where seldom is heard a single word
      And the skies are not cloudy all day

      How often at night when the heavens are bright
      With the light from the glittering stars
      Have I stood there amazed and asked as I gazed
      If their glory exceeds that of ours

      Where seldom is heard a single word

          The Antarctic gate was in storage after being retreived from McMurdo.
          The original Giza gate was in use at SGC until it was beamed up into Thor's ship before it crashed into the pacific.

          Then the A-Gate became the primary because the G-Gate was thought lost in the Pacific, but it was infact retrieved by the Russians and they ran their own gate program.

          It was the A-Gate that was destroyed by Anubis. The G-gate was then purchased back from the Russians after they figured out that Anubis's gate-blower-upper-thingy was destroyed.

          Nope, the one in Giza was used to escape a crashing Asgard ship, after which the Antarctica Stargate was moved to Stargate Command. The Russians recovered the Giza Stargate from the ocean floor and started their own Stargate program. Later, a new weapon developed by Anubis led to the destruction of the Antarctica Stargate. Stargate Command arranged a deal to lease the Giza Stargate from the Russians, and 'purchased' it outright by giving the Russians a Daedalus-class ship (the Korolev).

    i know they don't go all the time, but at that far south, wouldn't you get them pretty frequently?

    http://en.wikipedia.org/wiki/Aurora_(astronomy)#Frequency_of_occurrence [wikipedia.org]

    The aurora is a common occurrence in the Poles. It is occasionally seen in temperate latitudes, when a strong magnetic storm temporarily expands the auroral oval. Large magnetic storms are most common during the peak of the eleven-year sunspot cycle or during the three years after that peak.[citation needed] However, within the auroral zone the likelihood of an aurora occurring depends mostly on the slant of IMF lines (the slant is known as Bz), being greater with southward slants.
    Geomagnetic storms that ignite auroras actually happen more often during the months around the equinoxes. It is not well understood why geomagnetic storms are tied to Earth's seasons while polar activity is not. But it is known that during spring and autumn, the interplanetary magnetic field and that of Earth link up. At the magnetopause, Earth's magnetic field points north. When Bz becomes large and negative (i.e., the IMF tilts south), it can partially cancel Earth's magnetic field at the point of contact. South-pointing Bz's open a door through which energy from the solar wind can reach Earth's inner magnetosphere.
