"The joke is why are astronomers on mountaintops, and the answer is, that’s where people want to put them. The real point is that, when you go to a mountain top, you’re above a lot of the atmosphere, above the dust and all the stuff that interferes with the light. In Chile, the fringe of the Atacama desert is a very good place for us, there are lot of mountains, the weather is good, the conditions are as good as they get. There just isn't any place better for us."
