Stargazers set sights on 'dark sky' designations for Yukon parks
The Yukon Astronomical Society (YAS) is proposing that Kluane National Park be a "dark sky preserve," and Whitehorse's Chadburn Lake Park become an "urban star park," as designated by the Royal Astronomical Society of Canada (RASC).
The RASC defines a dark sky preserve as "an area in which no artificial lighting is visible and active measures are in place to educate and promote the reduction of light pollution to the public and nearby municipalities." An urban star park, meanwhile, is described by the RASC as an area where artificial light may be visible, but "is strictly controlled and active measures are in place to educate and promote the reduction of light pollution."
There are a number of dark sky preserves across the country, with Wood Buffalo National Park in Alberta and the N.W.T. becoming the world's largest dark sky preserve, and the first in a park in Northern Canada, four years ago.
