World's largest dark-sky preserve

Did you know Canada..  Alberta's Jasper National Park is the world's largest dark-sky preserve as announced by Federal Environment Minister Peter Kent Friday.

Jasper National Park, established in 1907, is the largest national park in the Canadian Rockies. At 11,228 square kilometres, Jasper National Park's dark-sky preserve is larger than the combined total of the rest of the world's dark-sky preserves.

A dark-sky preserve is an area that is kept free of artificial light. The purpose of a dark-sky preserve is to promote astronomy and the reduction of light pollution. Canada is just about the only country with established and extensive standards for dark-sky preserves based on the work of the Royal Astronomical Society of Canada.
