(Phys.org) —Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, you have to do a little better than that. You have to go farther and higher, up to where the atmosphere is thin. And if you want to look at the stars for more than a few nights a year, you also need some place that is very, very dry. Clouds, of course, obstruct the view of stars and galaxies, but even water vapor in the atmosphere can interfere with incoming electromagnetic radiation.
