Town Turns Off the Lights To See the Stars 222

Hugh Pickens writes "Stargazing skies all over the world are disappearing, as the sky above New York City is Class 9 on the Bortle ranking and American suburban skies are typically Class 5, 6, or 7. But some places are making an effort to preserve their skywatching heritage as Exmoor National Park was granted International Dark-Sky Reserve status in November and people in the Exmoor town of Dulverton were challenged to switch off their lights as part of the BBC's Stargazing Live, demonstrating that you don't need special equipment to see the stars more clearly, if you have a decent pair of binoculars. 'The whole idea is to show that even a small town, which is still quite dark, can give off quite a lot of light,' says astronomer Mark Thompson. The event in Dulverton gained a lot of support from local residents and businesses. 'It needed a bit of organization to get everyone to say yes,' says town mayor Chris Nelder. 'We want people to just enjoy the night sky, to treasure the fact we have them and to look after them,' adds Claire O'Connor from Exmoor National Park Authority."

      I live in the country so I get a fairly good look at the sky. However, when I first moved into my house the first thing I did was go outside and shoot the mercury bulb with a pellet gun. The power company installs a "house light" on every property and they charge you about $10 a month to run it. I called and had them remove it later on. I told them it blew up one day and I didn't want it for safety reasons. Tried to get the neighbor to get rid of his, but he never looks at the sky so what does he care.

      You would be amazed to see the difference between the sky above a city or town and what it is like out in the country well away from lights but also from air pollution. When I go out of Silicon Valley, where you can see some stars, down to Pacheco Pass in the mountains southeast of the area, the difference is immense. You can see the Milky Way in all its glory, and then you realize what you see in the city is like having a gauze bandage around your head.

        I'm not sure pollution plays much of a role at all. Many parts of the country have pretty terrible air quality, but still have incredibly clear skies at night. Air pollution rarely stays in one place and the sticks can often be just as polluted as a nearby city.

          She kept saying things like "well, as a woman.. well, you know". And though I knew what she was trying to imply, I wanted her to come out and say it, so that she could hear how stupid it sounded. She never actually did get to the point though. If she was actually scared of me, she wouldn't have approached me and started chatting, she would have just called the Police.

          They've been doing that around here lately. The local utility has been switching to LED streetlights and they're wonderful. Rather than one bulb that has to burn out there is an array of like 20 LEDs that have to individually burn out. The color is much more pleasant than the older orangish color. Plus, I'm sure that they use a lot less power.

          On a side note after about 25 years, they've finally fixed the street light out front of my parent's place.

            For astronomers that can actually be worse. For one, if they're not reducing the current through the light to take advantage that more of it is going to its intended target, then the increased reflected light from the street still causes light pollution. More importantly, those white lights emit all over the spectrum, and are incredibly hard to filter out. The ugly orange lights only emit at a couple of frequencies, and is very easy to filter out.
          • The orangish color is there for a reason. It allows you to see objects like people and animals, and it does not wash out brake lights.

            Flagstaff was the first Dark Sky City in the world, and achieved that by making nearly all outdoor lighting Low-Pressure Sodium (LPS) emission lamps. LPS is much lower power than High Pressure Sodium or Mercury (the typical alternatives), thus saving the city massive amounts of money on energy bills. In addition, LPS is monochromatic, making it easily blocked by even mildly sophisticated amateur astronomers. And the minimal skyglow has allowed the local research telescopes to survive, thus pumping tens of millions of dollars into the local economy.

        To be fair, you can usually get away with using better targeted, more directional lighting.

      The main reasons for street lighting is to make obstacles and pedestrians more visible to motorists, to allow pedestrians to move around without carrying a torch, and to make them feel safer.

      In this case, they'd closed the roads around the town for this stunt, so no need for worrying about cars, and a good fraction of the population of the town was out on the street, so there were fewer empty dark back alleys down which to get stabbed (plus it's a small rural town; if it's anything like mine crime is generally livestock related...), and everyone there knew about it months in advance, so I'd expect they were stocked up on torches and batteries. It was just a shame it was so cloudy!

      If you have never seen the stars without light pollution, go to somewhere in the middle of nowhere and have a look. It's quite hard to do in the UK, as our population density (and thus light pollution) is many times that of the US, so there aren't many really empty places left. It's a real tragedy that for a little convenience and marginal extra safety we've given up our window seat at the edge of the rest of the universe.

    • Most outdoor lights are very wasteful because too much of the light doesn't go where it is needed. Most streetlights only throw about half of their output downward with the rest going sideways (and over the horizon toward the sky) or upwards. There ARE fully shielded streetlights that throw almost all of their light DOWNWARD and these can be of lower wattage to give the same effect without causing light pollution. Even better if they are low pressure sodium lamps which emit light on only two wavelengths

    I live in a very dark neighborhood... no streetlights within about a mile, and lots of trees (makes stargazing... challenging.) Unfortunately, some of the neighbors don't feel safe unless they leave lights running all night long. It's a very basic human trait: fear of the dark. We have less crime in my dark neighborhood than many nearby well-lit ones, but facts don't erase fear.

      That's probably because burglars, too, fear the dark.

      Just like the Simpson's tra-map-poline joke, if you want something stolen in my neighbourhood, you add a padlock and chain.

      I have no light or even a fence at the bottom of my garden. All the garden tools are left where they fall (against a wall, normally) and yet they've never been stolen.

      Everyone else's sheds and garages are broken into yearly.

      Maybe the criminals are afraid of my dark and open garden?

      It's actually the stone flint pathways that puts them off. They're noisy to walk on.

        As an opposing point, I used to live in a neighbourhood where it was pretty common knowledge that if you didn't chain and padlock your BBQ to your house, it would be stolen within a couple weeks. Usually in daylight while people were at work/school. In this case, the thieves did go after the easiest targets.
      • I think nefarious individuals are afraid of motion sensor lights, and dogs, not that I have any, but they don't know that, and many of my neighbors do.

        I do have some motion sensor IR cameras... all kinds of interesting creatures moving in the yard in the middle of the night, none on 2 legs yet.

    I've always lived in semi-rural or town areas in a fairly packed part of the UK. You can see a few stars on a good clear night but there's still a lot of light polution.
    I recently went on holiday to a farm in the middle of nowhere in the Yorkshire Dales. I was utterly astounded to find out you can actually see the Milky Way at night - it blew me away. I spent hours just lying on my back in the grass with my mouth open. Wine probably helped. I feel so bad I've missed such a wonder for all these years.
    • Seeing the Milky Way (and the host of other visible-to-the-naked-eye stellar phenomena ) is one of those things I always took for granted growing up. Never thought about people never seeing it. I suppose it's sort of like snow... you never think about the fact that some people may never see snow with their own eyes when I'm used to seeing it by the yard.

        I grew up in and around London. I consider it a good night if I can see more than the Plough with the naked eye after ten minutes of standing and letting my eyes adjust.

        My girlfriend (from a rural part of Italy) keeps on about showing me the Milky Way, meteorites and fireflies. I have honestly never seen any of them.

        The only way to "see" more than a handful of the brightest stars near a city like that is to have a very sensitive camera and a "BULB" mode where you can do exposures of whatever length you ne

        • We had a German family in the same hotel. The first night they were outside looking at the stars and someone said "There you are, we have better stars than you do in Germany". The husband took it quite seriously and said "You are right, we live in the Ruhr and you can never see stars clearly through the haze".

          I imagine this has changed nowadays.

    • I have a cottage in the northern midwest of the US. The night sky up there is absolutely incredible. The milky way is clearly visible, but the real star is the northern lights. I love it when i can take someone there to see them for the first time. The reaction is always the same, "Holy SHIT! How can that be real?"

    This is why I like going back to my hometown, especially during the winter when the sky is cold and clear. Drive to the top of the nearest hill and you can see about ten billion more stars than possible within 20 miles of the city where I live now. My girlfriend grew up in the suburbs and is amazed by the sheer number of stars visible where I grew up. This is exactly the reason why we stick everybody in one big city in New York - so the rest of us in the state can still enjoy the great outdoors.

    • It's also why I enjoyed going to a small state school in a small town (~2,000 full time residents, plus ~1,500 students in dorms or apartments in town). The college's observatory was less than a mile away and had a decent telescope (especially compared to the $100 telescope I had when I was younger). It's freaking amazing what you can see on a clear night even with a relatively small observatory... made having classes until midnight well worth it.

  • Not only that, but someone taking part in Stargazing Live reportedly discovered a planet [bbc.co.uk]! A nice little series.

    I couple of years ago I went up to the middle of the Alleghany National Forest in the middle of the day (I live in a suburb of Pittsburgh) to wait until night to see what the skies were like from up there. I've been meaning to go to the Cherry Springs star parties for a while and missed my chance so I felt this would give me an idea of what some naked eye star gazing is like from a remote part of the woods.

    So I waited and the sky was really fantastic. I've never seen anything like that from around m

    More info over at www.darksky.org [darksky.org] . It costs a lot of money/oil to keep all those lights on. Is it worth it? Have your children seen the milky way?
  • My experience is that light pollution only happens when there is smog in the air. In summer, or after strong winds the sky is usually clear. So I think a better approach would be to reduce air pollution, which in turn would reduce light pollution too.

    About 35 years ago I got the chance to sail to Hawaii from San Francisco in a small (31') sail boat. Believe me, when you are 1000 miles from the nearest light the night sky is astounding. It is very obvious why the ancient people put so much stock in the night sky: it hangs over you like a presence you can feel.
    More recently I used to go to Death Valley for a good night sky, but that is becoming increasingly problematic. Even when there is no moon, there is so much light from Las Vegas and Los Angeles it looks like the moon about to rise (in two places!). *snif*

      Also when you are in that dark of skies you can see the earths ring of dust in the early morning.

    This would be reduced significantly.

    Honestly, the U of M did this. they threw away all the crap street and building exterior lighting and replaced them with fixtures that do not waste light by spraying it upwards and sideways. All light is controlled.

    IT made a huge difference to the light pollution around their observatory on campus.

  • I live in the Boston area so the night sky is hard to see. I usually take a week off during the summer and travel to the family lakeside camp in New Brunswick, Canada. There, the night sky is so clear you can see satellites, plane lights, shooting stars, etc. It's amazing just to lay out on the dock and wonder.

One small step for man, one giant stumble for mankind.
