The Illuminati Project Pushes For Dark Skies In 2009 315

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."

      LED Street lights [ledlights.ca] should help a lot with this. LED illumination is a lot more directional and therefore there should have a lot less wasted photons/energy. As a bonus it saves money [www.york.ca] for the same level of illumination. Pilot projects [eco-can.ca] are already under way.

    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".

              correct. The pupil is effected (affected? - who gives a fsck) by the blue scale. The use of a red light for night time map reading etc allows the pupil to remain open and there is no visibility lost when the light is switched off.

              Try for yourself. Get a torch and a red filter and a blue filter. Go out at night and let your eyes get used to the darkness. Shine the torch through the red filter such that you cannot see any white lite. You will be able to see quite well after you switch the torch off. Now try with the blue filter. Once you switch the torch off you will have to wait until your eyes adjust to the darkness again.

            Red lights are used by people with telescopes. This page [stlplaces.com] has a good bit of detail on the biology behind night vision and different colors. The basic summary? If you want fast dark adaptation, use blue-green. If you want to see detail and can afford to lose peripheral vision, use very low level deep red. For general walking-around light. blue-green with enough red to get rid of the night blind spot (or dim white). If you need to see color, dim white.

      As the cost of energy rises in the medium future, I think this will sort itself out. Towns will question why they are spending so much on lighting and cut back. Generally, households use all they electricity they can afford so rising prices will make people cut back. People don't (usually) run the AC in the summer with the front door wide open. People don't like heating/cooling the outside. It's too expensive and wasteful. Similarly, I think people will curb their habits of trying to light entire cities at night.

          If crime was that much of a worry, they would probably be installing blue light. [softpedia.com] In energy conscious Japan, in the area where I was living they were doing exactly that. I just can't see them doing that in the US of A.

          Your comment uses something that he never said (slightly darker), to base your whole argumentation off of it.

          The point of this whole thread was, that you can reduce light pollution without reducing brightness on the street at all.
          in fact, mirroring the light back to the ground instead of losing it to the sky, will make for more efficient lights. So just installing mirrors will brighten the streets!
          Installing lamps that are darker by the same amount, that they gain by reflecting everything to the streets, will make them exactly as bright as the old lights, while saving energy.

          That's why some grand-parent post called it a win-win.
          But you could not afford not to ignore that, could you? Or else your whole argumentation, and with that, your whole point of view, would collapse like a house of cards. And that you just could not accept.

As for safety, there are several types. As far as traffic goes, street lights are generally positively correlated with safety at intersections, but lighting of roadways between intersections shows mixed results in the studies I've seen.

      Even on the darkest of nights, you dont need any light to find your way around in the dark. Give yourself a couple minutes to adjust and you will do fine. If you really need light, get a maglite and some blue gels for it. Using a blue gel will let you turn on the light for a second or two while you check for the boogie man, and when you turn it off you'll have most of your night vision back right away.

Since 1990, global dimming has been decreasing, so there's an increase in light getting through the atmosphere. The total global dimming now seems to be about 10%.

        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 [allenpress.com] as well as 'plain old' Optical Depth [wikipedia.org], 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 [wikipedia.org]'. A short article over at 'Sky and Telescope's" site, ties it all together [skyandtelescope.com]. 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.

Often times lights are necessary for safety and although you may be able to encourage people to use mirrors and what not to maximize the amount of light hitting the ground rather than going up into the sky, you're not going to have much luck getting populated areas to turn down the lights much. Lighting helps avoid crime.
