Throwing a star-party: Filmmaker chronicles fight against light pollution

The Milky Way is a sight to marvel in all its glory, the human eye can observe thousands of its seeminglyendless stars that span across the dark sky in onecreamy stroke.

But less than one per cent of Canadiansget to witnessit regularly, according to some studies.

And the Journal of Science Advancesreports that80 per cent of all North Americans and one thirdof all human beings can't see it at all due to light pollution.

But there are groups of people dedicated to preserving the night sky in Canada, and they're the subject of a new documentary by filmmakerBrandy Yanchyk, titled Ambassadors of the Sky.

The idea took rootwhen she visited the Jasper Dark Sky Festival an annual gathering of stargazers trying to evade the side effects of human-made light.

"I found out there [were]star partiesacross Alberta and B.C. and that fighting light pollution was a big thing that they were trying to do," she said. "I thought this would be a really good idea for a film."

Star parties are gatheringsin designated dark areas pristine placeswhere there's hardly any light pollution. Preserves include McDonald Park in the Fraser Valley, as well as Jasper and Wood Buffalo parks in Alberta.

"People hang out, they talk about the sky ... some people just observe in their telescopes," she said. "It's just a big place to get together and share a passion."

Some of the attendees are what Yanchyk callsambassadors of the sky volunteers who travel from star-party to star-partyto educate communities about the importance of a dark sky and the consequences of light pollution.

Studies suggest that light pollution has a negative affect on the migration patterns of some birds, and some have even foundlinks to increased risks of cancer in humans.

Not to mention, there's aspiritual connection humans have to the stars that is being threatened, saysYanchyk.

"There's something very magical about being in darkness and just looking up in the stars I mean, its part of us."

Ambassadors of the Sky is now airing on CBC's Documentary channel.

It is also available to stream online.
