Dark Sky

Overview

Dark skies around the world are disappearing as light pollution continues to increase. According to a 2016 study of light pollution led by the Italian Light Pollution Science and Technology Institute, more than 80% of the worldwide population and more than 99% of Europe/U.S. residents live with light-polluted skies, and nearly 80% of North Americans cannot see the Milky Way (The new world atlas of artificial night sky brightness).

Not only does light pollution waste energy and contribute to climate change, it negatively affects ecosystems, wildlife, and humans alike. LED lighting, while great from an energy-consumption perspective, tends to emit brighter white-blue light that is most damaging in terms of light pollution. The list of negative impacts of light pollution is far too long to include here, but it has been linked to issues such as millions of annual bird deaths, turtle hatchling disorientations, and disruptions in mating timing. In humans, it has been linked to numerous diseases including cancer (Our nights are getting brighter, and Earth is paying the price).

Dark Sky at the Field Station

As the world becomes more aware of the consequences of light pollution and works to reduce it, we are fortunate that the field station does not have this issue. In 2015, Capitol Reef National Park was designated as an international dark sky park (Capitol Reef Night Sky). It offers excellent night-sky viewing. The International Dark-Sky Association (IDA) certifies not just national and state parks as "Dark Sky Parks," but also certified communities. Torrey., the nearest town the the Field Station, was Utah's first Dark Sky community. Learn more about how to get involved on any level.

At the field station, we strive to minimize light pollution. We have limited, low-wattage, downward-facing external lighting. All windows are equipped with blinds that are closed at night to reduce the amount of light that leaks from buildings into the environment. Our visitors are treated with wonderfully dark skies that can be enjoyed with the naked eye, and also with our telescopes, including a 12-inch Dobsonian. In fact, CRFS grounds are so dark that we set up the telescopes just outside the buildings!

Dark Sky and You

Light pollution is not an intractable problem. While cities/organizations must do their part, individuals can contribute as well. There are numerous steps individuals can take, such as using warm-temperature (red/yellow) bulbs, shielding light fixtures, installing motion detectors, and simply turning off lights and closing curtains at night.
