National Park Service Tracks Light Pollution

April 27, 2006 | While astronomy enthusiasts understand the importance
of dark, pristine skies, the science of measuring light pollution is
not well established. Now, researchers with the US National Park
Service (NPS) have released data as part of a program to measure the
impact of light pollution on the relatively unspoiled skies of western
US National Parks. The NPS Night Sky program, the first of its kind,
systematically detects and analyzes night-sky brightness in national
parks to understand current dark-sky quality and identify
light-pollution sources. . . .
