The Illuminati Project Pushes For Dark Skies In 2009
An anonymous reader writes "2009 is the 400th anniversary of Galileo's observations of Venus, Saturn and Jupiter published in Sidereus Nuncius ('Starry Messenger'). To improve scientific literacy, the NOAO and NASA are promoting dark-sky initiatives in 2009 to draw attention to the problem of light pollution which obscures nearly all night sky colors and objects except for the moon and a few bright stars and planets. Project Illuminati is a Flickr project by James Cann to showcase the beauty of light pollution to raise awareness and educate fellow Earthmates to lower energy consumption and become more curious about our place in the universe."
They are trying to promote dark skies (which of course show some amazing celestial bodies) by showing how pretty of a red sky light pollution makes???

getting out into the middle of nowhere makes. On a clear night out in Yellowstone, for example, there are so many stars in the sky it can be hard to find constellations you're used to seeing in the city. Really beautiful.
People need to get past the idea that you have to try to illuminate every shadow. All you're doing is ruining people's night vision, and thus making the remaining shadows "darker".

In Galloway in Scotland, the local tourist board is trying to set up a dark sky park. The area that they're planning to open it is apparently the darkest place in Europe.
There are already two in the US, in Utah (http://www.nps.gov/nabr/parknews/news040507.htm) and Northern Pennsylvania (http://www.dcnr.state.pa.us/stateparks/parks/cherrysprings.aspx). This BLDGBLOG article mentions suggests World Heritage sites for experiencing darkness, set up to protect dark areas: http://bldgblog.blogspot.com/2008/12/dark-sky-park.html
I recently visited Poland (Krakow) and there the level of street lighting was a lot lower, resulting in reduced light pollution. Streets were mostly lit with light reflected from buildings. It's surprising to be able to see the night sky from the middle of a city of 1 million. It's not comparable to countryside darkness by any means, but it really changes the character of a city.
I dreamed of Freud: What does this mean?
Whenever I explain your point to other people, they look at me like I'm from another planet. I usually tell them that if they really want lights, they should use red lights and explain to them why it doesn't ruin their night vision and why astronomers and photolabs use red lights.
My neighbors are typical americans - they came out into what was the countryside (our house was in the middle of nowhere for decades, now it looks like suburbs.)
After they built their McMansions, closer together than some of the houses in the city, using up the woods and fields I used to romp in, they installed huge arrays of sodium-vapor lighting on their houses, which they leave on 24 hours a day. For "security," or to make it homey, or whatever.
I used to go in the back yard to stargaze, I could even see the aurora borealis sometimes - in NY! We never even bothered to replace the outside floodlight over the driveway for years after it died, but the latest thing for all these new people seems to be to have a gazillion lights. Houses, cars, SUVs, three-wheelers, all festooned with lights - long driveways lined with bright lights left on at all times.
I don't get it. Why do people move out to the country if they don't want it to be like the country?
This space available.
In order for the light to remain the same, you'd probably have to reduce the power to the lamp.
The cost of that cleanup, of course, will be borne by taxpayers, not industry.
Flagstaff, AZ, home to the Lowell Observatory has had a black sky ordinance on the books for 50 years now and it works wonders.
There is plenty of lighting for the town and yet you can see stars like you should be able to see stars.
Beer is proof that God loves us and wants us to be happy.
... as a knife wielding teenage gang member I welcome any dark sky initiative - and I can assure you that all my victims will be seeing stars when I've finished with them (shortly before they die in a pool of their own blood ...)
At last, the needs of amateur astrologers, penny pinching local councils, and muggers finally coincide! Happy days!
Think how much easier it would be to see the stars if we just stopped making electricity. The night skies would be black like they were a thousand years ago. We could all go back to living in caves and wearing fur, no wait, we can't kill animals, and wearing fur is evil and sit by the fire, no burning wood produces CO2, so we'll sit in our dark caves, huddled together to stay warm and slowly starve to death. But then there wouldn't be anyone to look up at the stars. And that is the true goal of "environmentalism".

railing against light pollution by taking pictures showing how beautiful it is... kind of like raising diabetes awareness by building a giant sugar sculpture.
Global dimming specifically measures the reduction in the amount of sunlight that reaches the surface of the Earth because of atmospheric aerosols. It has only been measured for fifty or so years and does not take into account the reduction in surface irradiance that has occurred because of natural or man-made causes in the the nearly two hundred years prior to when record keeping started. Aerosol Optical Depth as well as 'plain old' Optical Depth, are measures of the transparency of an optical medium -like the atmosphere- at optical wavelengths and have a greater effect on dim, point-sources, of light -such as stars- than they do on brighter extended sources of light -the Moon and the Sun- since small aerosol particles in the atmosphere have a greater tendency to scatter the light -which reduces the apparent brightness and increases the extinction- of point sources. If the atmosphere was truly 'clean', then the only phenomenon that an observer would have to contend with is 'Rayliegh Scattering'. A short article over at 'Sky and Telescope's" site, ties it all together. The reduction in atmospheric transparency since the Middle Ages due to man-made pollution has, by some estimates, reduced the brightness of the stars in the night sky by as much as twenty-five percent. There was an article published last year -that may have been mentioned here on \.- that discussed this very situation. Unfortunately, it escapes both my memory and that of Google.
