We’re forgetting what darkness feels like

I did also have a cool experience, deep in the backcountry at a high elevation camp some years ago: we went to sleep in a gale, the tent flapping all around, with a cloudy sky. I thought we’d get a big storm, but I woke up hot at 3am, the air totally still. I slid out of the tent and the sky was completely crystal clear. An incredible spread of stars. I watched for a while and noticed a reddish glow on the horizon. We were so far out and it wrapped around in all directions, so I knew it couldn’t possibly have been a town, but I was puzzled. I learned about airglow when we got out of the woods: https://en.wikipedia.org/wiki/Airglow
I've only really experienced this once in my life. I was young teen, my family was visiting some family friends at a remote cabin. I woke up during the middle of the night and went out. It was a crystal clear winter night, and I was completely blown away at what I saw.
Once I had gotten over the shock, I thought "no wonder they called it the milky way". It was so bright, it felt like a new moon just smeared all across the sky.
Sadly not had the chance to experience that again. The then-remote cabin got swarmed by hundreds of others and so it's no longer pitch dark at night there.
I have it as a goal to get out in a really dark zone and see it again.
For reference, the Bortle Scale[*] goes from 1 to 9, with 1 being pristine darkness and 9 being Manhattan.
Also worth noting that the Milky Way is brighter in early summer, late May to mid-July, as that's when the Earth's night sky is facing the most towards the Galactic Core. Go find yourself some deep dark sky on a new moon, and sit back and enjoy the enormity of the cosmos.

Well I'm in Norway so those months we don't really have dark nights like in the winter.
Still, the sky was literally filled with light. Not just the milky way, but it was by far the most prominent feature.
When I was young, I used to lie on my back staring up at the sky, trying to grasp the incomprehensibly vast distances I was gazing at. It's really nuts when you think of it that way. The mental vertigo of it all is extraordinary.
I wonder if the psychological impact is really the absence of the true night sky that we have. Maybe the awe we feel at seeing the true night is what we’re supposed to feel? Something to think about.

This is the most accurate map and it still under reports light pollution under 21.5sqm https://www.darkskysites.com/
Worse satellite constilations may make it impossible to have a dark sky anywhere: https://arxiv.org/html/2604.09427v1
Led lights have caused such a massive increase in light pollution, let alone the effects on humans due to the blue spike, that they should be banned outright.
I was lucky enough to witness a thunderstorm over the desert, too. Too far for any noise to reach me, I just saw the clouds lighting up on the horizon. Incredibly beautiful, and not a little spooky. I totally understand why there are so many UFO sightings there.
I can see the milky way but I wouldn't describe it as "a new moon just smeared all across the sky" like one of the other commenters. It's more like just a vaguely higher-density strip of stars.
My location is 21 SQM according to the DarkSkySites map.
In my view we should simply have improved on what already existed, instead of blue-pumped LEDs we should have used monochromatic amber ones like the SOX streetlights which were once ubiquitous in the UK. Night actually looked like night back then, rather than a cheap and nasty approximation of daytime.
They are friendly in the same way the feeding a baby petrol is. Sure it's more energy efficient, but humans aren't machines where input = output. It's going to take decades to get rid of all of them, and then even longer for all the cancers that blue light causes to work themselves out. It's amazing that we invented a new asbestos and put a green wash on it.
Blue light gives people cancer?
In mice the link is clear and simple to test.
https://pmc.ncbi.nlm.nih.gov/articles/PMC11311462/
In people for what cancers have been investigates there is also evidence of a link, but not enough studies have been done to say that it's the case for all cancers. This is absense of evidence rather than evidence of absence.
Because they're so close to the earth's surface it doesn't happen all night because they'll be in darkness too.
The moon of course has the same brightness, as if you were in a city. This is the ability of your eyes, to see in the darkness, if there are no too bright other light sources.
My family has a cabin in a true dark area and when I bring people there I often have to physically take their phones and lights away to get them to see a full night sky. They literally cannot resist looking at a bright ass light more than 60 seconds, and often with their screens on full brightness too. It makes me feel crazy sometimes, telling them they can see just fine without lights if they wait a minute or two is like you telling people they should try walking sometime and they act like you asked them to join the ministry of funny walks.
A couple of years ago there were reports of aurora borealis sightings in parts of England. That night looked like it was going to be clear so I decided to take a wander into a large meadow not far from town. Unfortunately lots of other people had the same idea. Cue a bunch of people standing around in a meadow looking at their phone screens and briefly glancing at the sky complaining that they can't see anything. Regular people just have no concept of darkness or night vision. I gave up after being blinding for the tenth time by someone's phone light.
But surely a lot of apartments have some room or floor without windows? If you don't turn your internal lights on at night, sure that's not true darkness, but should be enough to experience night vision, no?
I only recently learned that visual snow syndrome is a thing, and that most people don’t have it. For me, there is a faint background of multicolor static (analog TV on a dead channel, for those who remember that) on everything, all the time. Light washes it out, so it’s only in the deep dark that I’m absolutely surrounded by it. (It’s basically visual tinnitus, which in turn lead me to discover that I’ve also had auditory tinnitus my whole life, it’s just a soft static not a “ringing” so I never realized it was the same phenomenon.)
(Well, except for YouTube channels)
I don't think I notice it that much with the night sky unless the stars are faint though.
To clarify, a similar case: most people are able to see Haidinger's Brush [1], even if they have never noticed it. Why? Because it's not very noticable, so they don't pay attention to it.
It's a badly named syndrome in my view, since most people younger than me have no idea what TV snow is, and some of the symptoms aren't visual.
Do we need bright white flood lights in places like Portland? Yes, they strongly correlate with reduced crime on the premise. This is the cost of a medium trust society.
Find a way to not have people regularly vandalize and B&E; many of the countermeasures can go away.
I live in a dark sky community and my property is unlit. I don’t worry about people walking onto my property at 2am.
Regardless, if one still lights up their own property due to anxiety, it's not a justification for causing light pollution. That light should remain on their property with angling and shielding.

> It is concluded that street lighting continues to be an effective intervention in preventing crime in public places. A narrative synthesis of effects of the eight new studies and a meta-analysis of 17 studies confirmed this conclusion. In pooling the effects of 17 studies that could be included in the meta-analysis, it was found that street lighting led to a significant 14% decrease in crime in experimental areas compared with comparable control areas.

If you want dark skies, take some friends to a city council meeting and make your case for similar ordinances. It's doable, even in a place like Los Angeles.
Unfortunately, I have never seen stars the same way again. Whenever I think I might see them, I encounter some light pollution which dulls them down.
Oh, what I'd give to experience darkness and to be under the stars.
(That's obviously a lie because I love my conveniences and give up the darkness and the stars for said conveniences every single day)
OMG, it is so bright that it blots out all but the brightest stars. Something needs to be done about this.
Well, I'm sold. Let's nuke the moon
In 2011 I left the Dallas Fort Worth area and headed west, met a nice girl that lives on a 180 acre family farm and the night skies are amazing! You can see the dark voids (dense dust) snaking through the Milky Way. Now, I'm saving money to build a small observatory out front, new telescope and a permanent pier to set it all on.
(And it's not just light pollution here, but also noise: everything here in Canada seems louder. Louder cars, louder machinery, people playing loud music in their yars, more cars in city centers. Man do I miss the Netherlands)

No need to waste energy lighting up the sky; direct it toward what you need illuminated.
Also, the company the article mentions is Reflect Orbital.
Love the idea of harnessing more sun, but really disturbed by the potential destruction of darkness that it could cause when deployed at scale.
Life on Earth evolved with the night.
Does feel a bit eerie on moonless nights when the coyotes start howling though.
A spot of light around your dwelling, and a sea of nothing around. Barely able to make out the treeline against the sky. Hearing grows keener, mind amplifies the sound of every falling leaf into a predator stalking the forest. Standing there in the light you feel horribly exposed, everything can see you.
The lizard brain awakens and screams at you to get out, get away, hide! Your consciousness brain knows that the worst thing out there is probably a fox. But the primal parts responsible for your basic survival want none of that logic. They scream for a hiding hole.
I miss the 70s/80s/90s era of street lights where they were warm and easy on the eyes.
such a sad state of affairs. everything good must end I guess.
There's a particular observatory in Hawaii that is supposed to be amazing.
I'm sure there's plenty of other spots!
Seriously. I moved here. Even northern lights can be elusive due to this (plus, I live in a city). And where I live, I can read outside at night so the best time to see dark is during the cold times.
But more to the point, there is a lot of light pollution here. The best places are inland and plenty of other places get much darker. If you want to check out dark places, I've linked a light pollution map.

I just came back from a trip to Yellowstone, staying at an RV Park in Idaho that had designated themselves as a dark sky RV park, which mean no external lights after 10pm. The night sky was glorious with the Milky Way visible almost from horizon to horizon. I wish more city dwellers could experience this so we could do something to tame the completely unncessary and wasteful light pollution.
Bring back the orange I say. Red has certain connotations but orange is friendly enough and doesn't keep you awake
While also - paradoxically - forgetting that there are plenty of dark places just outside your city if you're willing to drive to them.
Perhaps it's in service of baiting you to click.
It's like wishing that tall high density housing didn't block your formerly great view, all while ignoring the fact that there's not enough affordable housing in your area.
Wishes without thought show naivety at best or selfishness at worst. I probably won't agree with kelnos, but at least kelnos thought about the problem surrounding his desire.
That's actually what I thought this article would be about when I first read the title!
I know for a fact that just putting old school light shutters on streetlights so they don't leak into, say, bedrooms and stay focused on pavement and sidewalks, and dimming them off hours, would be a huge change that doesn't diminish utility at all.
It does though, by redirecting funds & human effort that could be used for more lighting.
Here's a counter-anecdote though, to give you hope.
In Bondi in Sydney there's a lighting upgrade underway on the beach promenade; the plan was circulated so I got to take a look. As you hoped they indeed did deeply consider throw angles and what's lit & unlit, and ran a competitive tender to choose among many vendors, settling on one they lauded for their flexibility in offering products that can throw at specific angles and leave specific areas unlit. In the plan published for public comments they specify the exact angles needed with diagrams and everything. So it's possible! It requires public servants to go above and beyond, which does happen, just not all the time and not in all the places. But it does happen!
In the eastern half of the US and the western 3/4 of mainland europe, there are very few spots that are below bortle 4. In these regions of the world, people in big cities (i.e. most people) would still need to drive 1-2 hours just to get to bortle 4, let alone below that.
If you live in England, for example, there is nowhere you can go to see a truly dark night sky. If you live in New York City, it’s a 4 hour drive, and even that isn’t completely dark.
Close to Bend, you can drive up to the Pine Mountain Observatory when they open it (check the web site), and the views are amazing because you're on a 6300 foot mountain away from the city with clear air.
Milky way is not extremely clear there, but visible and its sort of mentally healing experience. When camping up in the mountains, this is way clearer. Clearest I've seen it was high on Aconcagua in South America, around 5500m high, with constellations unfamiliar to an european. That was almost over the top in terms of clarity and the amount of stars visible (including very clear Magellan cloud). Remote himalayan valleys are also good for this, as long as humidity is low (its either glow from other light sources or high humidity which makes stars less visible, in cities pollution adds to this).
Can't not love astronomy after such encounters. Its our home, this crazy universe, everybody should look up from daily crap and experience such awe from time to time, I've never met a person who doesn't enjoy this.
Human lives are a big price to pay to see some stars.
Is this that "vibrant culture" you keep going on about?
