Disappearing Darkness
For those of us that live in cities, looking up into the sky to see the Milky Way, planets, nebulas and other stellar wonders is not so easy. And it's only going to get harder. This piece by Megan Finnerty appeared in The Arizona Republic, and is worth your read. Have you ever thought about the amount of light pollution your lights are spreading? Did you know light pollution exists? Beautifully written, this piece explores the aspects of light pollution that are being ignored, what can be done, and what it means for us if we don't change our idea of light pollution. Megan, writing for the Arizona Republic and a lover of the Grand Canyon, focuses her discussion around the light pollution caused by Greater Phoenix, and how in the next 10 years, you might not be able to see the Milky Way from the Grand Canyon, even on a very clear night. This problem has issues beyond casual viewing: 3 of the 4 largest telescopes in the world are being threatened by light pollution. Soon, astrologists will need to relocate to darker places: Hawaii, or farther, to be able to make new discoveries of what is in our universe. I definitely recommend giving the full piece a read to get the idea of just what is at risk. The first image here shows the Milky Way. The second shows light pollution in the US; the third, an advertisement to check out the Milk Way in the canyon. And lastly, a view of just what light pollution is.

Thank you for sharing this piece @hikaymm I've definitely heard of light pollution, but I didn't actually realize how intensely the amount of light in my childhood area had grown until I discovered that my kids are much more afraid of dark, forest ridden areas than I ever was, and I think that simply has to do with the fact that I was more accustomed to darkness growing up than they are today!

@greggr I actually didn't think of that; I'm not really afraid of being out in the darkness, but I definitely do feel comfortable in the range of "glow" aka where there is more light pollution! And that's probably one of the reasons people don't even realize it's a problem.
