Oh, What a Beautiful Morning!

We typically see photographs of telescopes at night, juxtaposed against a sky full of stars. In this gorgeous sun-drenched image, we glimpse a different side of the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab. The early morning Sun bathes the observatory in a warm light. The locale might look inviting, but it actually is not a very friendly environment for humans. Modern observatories are typically built at locations that are “high and dry”. This is because the atmosphere needs to be as thin and arid as possible in order to get the best possible observations. Furthermore, the telescopes must be located far from highly developed areas, in order to avoid light pollution. Therefore observatories such as the CTIO represent concentrations of highly technical buildings in otherwise relatively deserted landscapes.
