Happy International Dark Sky Week! Did you know that northern Minnesota has some of the darkest skies on Earth and that the BWCA (Boundary Waters Canoe Area) has been designated one of only 17 International Dark Sky Sanctuaries on the planet?

Recent photo from my local FB Lake Superior Birding Photography Group for you to enjoy 😎

(By the way, this is not a photograph taken in the BWCA, but taken on Lake Superior’s north shore, but does give a nice representation somewhat of the clear dark skies with this capture of the Milky Way.)

Earth at night. 🌏🖤

Dark skies help us see the brilliant color of auroras, pinpoint constellations and other planets in the night sky, and are important for the health of plants, insects, animals, and humans. #DarkSkyWeek

Scientists compared nighttime lights seen by NASA satellites and @cdc health data.

They found that poorer, non-white neighborhoods experience more artificial light at night, which can disrupt circadian rhythms and cause sleep deficiency. #DarkSkyWeek

It's International Dark Sky Week! 🌌

My plans: remove excess lighting outside our home, especially lights that point up or spill out. Starting with detached things. Updating the fixtures on the house is gonna be a longer project 😅

Should urban areas backing onto national parks be mandated to obey #DarkSkyReserve policies?
