Observatory construction sites: Consider the factors that go into selecting telescope construction sites
What type of site would you look for to build a large visible-light observatory? Where would you want to build an X-ray telescope? Would these be the same or different, and why?
For a visible-light telescope, students need to consider altitude, weather, and light pollution. For an X-ray telescope, they should only consider a space telescope above the Earth's atmosphere.
