From the National Park Service:
BIG BEND - Big Bend National Park has recently completed the first phase of a partnership project to improve exterior lighting throughout the park.
The first phase includes dramatic improvements to the exterior lighting at the Panther Junction Visitor Center and the Panther Junction Service Station. The work has been accomplished through grants from the National Parks Foundation, the Friends of Big Bend National Park, Forever Resorts, Inc., and park staff.
These grants intend to improve Night Sky Lighting throughout the National Park Service, and Big Bend National Park is the first park to receive the benefits of this grant. The goals of the Night Sky Project include reducing night sky light pollution, reducing electrical energy consumption, and providing adequate lighting.
The newly installed night sky-friendly lighting at the Panther Junction's visitor center entrance has reduced lighting from 480 Watts to less than 14 Watts.
At the same time, the new lighting allows the visitor to easily access the after-hours maps and information available at the visitor center entrance. The next phase of the project will be the Chisos Basin developed area, including the lodge and restaurant facilities.
Big Bend National Park has among the darkest and most dramatic night sky vistas in the lower 48 states, and is an excellent place for astronomers of all experience levels to enjoy the night sky. In addition, many visitors to the park enjoy the increased visibility of the night sky as a resource and experience in and of itself.
With the newly installed night sky lighting this important resource will remain available and more accessible for years to follow.
