Night Sky Team
The National Park Service Night Sky Team works across the country to document the effects of light pollution. Monitoring is currently taking place in 30 parks, and may expand to 55 parks in the future.
The program consists of collecting numerical data over time in order to track the “health” of the resource. The amount of light pollution is measured with a camera that is capable of precisely measuring light levels. Mounted on a robotic Meade LX 200GPS telescope, the camera takes 104 images to capture the entire sky. These images are stitched together, and by subtracting the light emitted by known individual stars, researchers generate a value for night sky darkness.
The parks of southern Utah were some of the first to be visited by the Night Sky Team. While most people realize that fewer stars are visible in a city, few probably realize that even remote parks like Canyonlands face the problem of light pollution. Preliminary data has shed light on many facts. Canyonlands has one of the darkest night skies in this ever-brightening country. However, several sources of light pollution can be detected. Casual observers can see lights of Moab, Blanding and Monticello, and the camera detects other light sources which reach high into the sky, eroding the view of the Milky Way and thousands of stars.
There is a lot to be done in order to restore the Canyonlands night sky to its full splendor. An assessment of our own outdoor lighting is necessary to insure that the NPS is taking proper steps to protect the night sky. Lighting retrofits can be relatively easy and inexpensive and can also be accomplished on an individual basis. When a light blows out it is a good opportunity to replace the bulb with a lower intensity bulb, or change the fixture to a full cut-off fixture, which directs all the used light downward. Retrofitting outdoor lighting not only helps restore the night sky, but also is environment friendly, energy efficient, and provides more security.
2003 Night Sky Monitoring Program Summary
Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals in Canyonlands. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. Scientists believe this and other behaviors signal dominance and facilitate courtship.
