The analogy to building telescopes at higher altitudes is especially right on. The other big advantage to both high altitude and the South Pole is the lack of water vapor in the air. For radio and microwave observations, water vapor has a tendency to glow, adding to a background that is already significantly brighter than the signal we're looking for. Hi John,

A response to your query about the rationale for building a telescope at the South Pole. I'm going go guess it's the same reason many terrestrial scopes are placed at high altitudes: thinner atmosphere and, colder temperatures mean fewer and less active molecules of air moving about that would tend to distort light waves reaching the scope. Also very low ambient light from Earth also means less distortion. Kyle, thanks for the article. A response to your query about the rationale for building a telescope at the South Pole.

You know, I once had to do a calculation on the intensity of gamma rays on Earth from a nearby supernova, maybe I'll do a post on that sometime in the near future. For now, just to whet your appetite, check out the website: <a href="http://en.wikipedia.org/wiki/Hulk_(comics)" rel="nofollow">http://en.wikipedia.org/wiki/Hulk_(comics)</a> for one possible scenario of what could happen.

Can I make a suggestion for your next article? Perhaps your thoughts on the controversial topic of the effect of Gamma Rays on Humans? I'd like to see an article on that.
