One Fifth of World's Population Can't See Milky Way At Night 612
An anonymous reader writes with this excerpt from Cosmos Magazine: "Light pollution has caused one-fifth of the world's population — mostly in Europe, Britain and the US — to lose their ability to see the Milky Way in the night sky.
'The arc of the Milky Way seen from a truly dark location is part of our planet's natural heritage,' said Connie Walker, and astronomer from the US National Optical Astronomy Observatory in Tucson, Arizona.
Yet 'more than one fifth of the world population, two thirds of the US population and one half of the European Union population have already lost naked eye visibility of the Milky Way.'"

I did spend a night in the Badlands of South Dakota -- and I think that is the most stars I've ever seen...it was like the entire sky wasn't black with pinpoints of light, but more of a fuzzy white with brighter spots.

'Light pollution' is all man-caused light, regardless of the source. Like noise pollution, it doesn't -actually- do any harm, it's just a clever way for someone to say they hate it.
I've never really understood this awe for nature that most people seem to have. It's not like a miracle created them... They were there long before you were born and will be there long after. They look vaguely interesting, but it's nothing to spend hours and hours staring it. They really don't move much, from our point of view.
It's a fine hobby (as most are), and astronomers have come up with some mighty interesting theories... But to say 'everyone should see the sky!' is the same as 'everyone should have a big back yard!' It's nice and all, but just not possible.

I grew up about 100 miles from the nearest metro area, and we could see the stars beautifully. We could see the glow of two different metro areas on the horizon (each about 100 miles away), but that was it. Since being an adult, I've lived in metro areas.
I was driving, either on I-10 or I-5, in either case I was running almost the full length of it. One trip, my girlfriend's daughter was with us. We stopped in the middle on nowhere at about 3am, where you couldn't even see the glow from any city, most drivers had stopped for the night, and even truckers were stopped and sleeping. We looked up, and saw everything. She was amazed. She grew up between two of the previously mentioned metro areas, so not more than 30 miles from either one, and the light pollution prevented seeing much of anything, even 30 miles out. That was the first time she saw the night's sky the way it's suppose to be seen. I had almost forgotten how amazing it was. We spent an hour stopped, looking at the stars. Sometimes those long drives are worth more than just getting from point A to point B. On I-5 and I-10, there's a whole lot of nothing, but sometimes that's the perfect place to get the most beautiful view.
Another night, I stopped with another friend at the exit in the middle of "Alligator Alley" (the southern most East/West part of I-75) to watch a meteor shower. Even though we were a long way from anything (more than a day's walk from either side), the light pollution still obscured our view slightly. We could see the brighter meteor flashes though, so it was worth it. Of course, Alligator Alley has it's name for a reason. I grew up in rural Florida, and I knew the sound of alligators. When we got out of the car, and stopped talking, I realized there were at least 5 alligators not more than 15 feet away, and it was too dark to see any of them. The mosquitoes felt like someone was throwing ping pong balls at us. We quickly got back in the car, and watched the show from there.
When I lived in the hills north of Porter Ranch, CA (on the edge of Los Angeles), even though we were above the smog cloud, I don't remember a night where we could see many if any stars. Most days we could look down on the smog cloud, and sometimes we could even see through it. :) I can only remember two days were I could see clearly from our hill to the other side of the valley (approx 8 miles). Living in the valley, there was frequently enough light pollution, where you could see at night with no moon, just from the light being reflected in the smog.

I have in-laws in suburban Phoenix, and there is an "anti-light pollution" ordinance in effect there. NO STREETLIGHTS. It is very eerie and strange, driving around dense suburbs, in near total darkness. You see the headlights of the other traffic, the endless banality of the lighted signs at strip-malls, but aside from the safety lights in the parking lots, no lights on the street.
In contrast, I (very fortunately) live in a fairly rural area in California; though we DO have streetlights. And the view of the stars at night is better in Phoenix. I have to drive about a half hour away from home to get a decent view of the night sky.
Now: compared to where I grew up - Chicago. . . I remember being disappointed when Haley's Comet came around. I couldn't even see the damn thing on a clear night. And that was after an hour's drive out into the "country".
Light pollution ordinances seem to be a very fascistic way to address this; public-safety is really more important than everyone being able to see stars from their backyard. It's an old notion that is apparently dying for us. It's sad. But as we (humanity) breed faster than cockroaches, I don't really see much alternative.
Perspective (Score:4, Interesting)
For me the best thing about being able to see the Milky Way is the sense of perspective you get from the realisation of what it is you're looking it in relation to where you are. Next time you get to see the Milky Way, think about how the galaxy is in a flat-ish plane, and how you and the band you are seeing are both in the same plane. Once you think about it, you mentally orientate yourself in this plane and it starts to mess with your perception of what's "up" and what's "down". The discrepancy between the local "up and down" that you experience on Earth and the bigger "up and down" you see from the Milky Way puts things into perspective in quite a powerful way, in that you stop seeing the sky as a big mass of stars and start to see how you + the Earth fits in to the bigger picture. Of course this may all be obvious to a lot of people here on /. but it isn't to most non-nerds, so if you're on a camping trip and want to impress your mates (or a girl..), try this, it works great ;)

If you live in a smaller town and even suggest the concept of "light pollution", people look at you and assume you are some sort of left-leaning-environmental-wacko. It doesn't matter how conservative your politics are--some people hear you discuss "light pollution" and they lump you into the same camp as all of the "tree huggers", "greens", "liberals", "communists", or whatever other groups they hold as "the enemy". I've even advocated just going a few nights a year without lights, coinciding with various meteor showers. Again, I must be a "nut job". After all, there's "no such thing as light pollution".
Of course, it doesn't help if you live in a town that is home to a major manufacturer of lighting components for public spaces and industry, either. Then such "light pollution" comments are viewed as attacks on the town's economy, too.

I've never had any luck doing any 'long exposure' shots with DSLR, I've got an old German 35mm that I use instead, especially for Lightning, DSLR's just can't get a good lightning shot.
Though I'm no expert, I think the big problem is that the DSLR is too intelligent with long exposure, it's trying to average the light values over the entire x seconds that the shutter is open, and when a lightning strike happens the brilliance is averaged out until you can barely see it.
As for stars, I've never been able to get the focus right, auto focus doesn't work and manual focus is very difficult when trying to use the viewfinder to see if those very very tiny points of light are in clear focus are not.

Me too. I went camping in the Boundary Waters (the lakes between US Minnesota state and Canada Ontario province) and thought it was a cloud. I'd never been so far out in the wilderness, and I found the light from the sky, without electricity for comparison, to be simultaneously beautiful and terrifying. I felt like something was really wrong up there, knowing that it wasn't.
That was the lesson I took back--well into my adult life: Most humans do not live on earth anymore. We've created someplace else, and when we find ourselves in our natural habitat, it's frightening.
I'm not saying that's good or bad or anything. It was just a profound realization--for me, anyway.
