I grew up in a rural place where we could see the texture of the milky way just stepping outside at night—it’s been fun taking friends who grew up in cities on wilderness backpacking trips and sitting out to watch the stars. There’s an awe to a true night sky that I think has real psychological impact.

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

> There’s an awe to a true night sky that I think has real psychological impact.

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.

It's crazy that you can "see" (identify) the Milky Way at a level 5/6 on the Bortle Scale, even in the light pollution of the suburbs. But you don't realize just how brilliant it really is until you're really out to a dark sky spot.

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.

I love watching the milky way on a clear, dark night. There are so many stars. Countless stars. It makes me feel really small and all my troubles (and the world's troubles) so insignificant. I love that feeling.

idk if it’s just my eyes getting old, or my LASIK, or the sky just not being dark anywhere anymore, but these trips don’t look the same to me as they used to. today it all just seems kinda static-y and fuzzy, but i remember my first night in the grand canyon being an absolutely amazing experience.

Outside of a few places like the Himalayas or Australia isn't not possible to see the darkness everyone lived in until street lighting.

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.

marcus_holmes•about 2 hours ago
I've driven across Australia a couple of times. Night on the Nullarbor is an amazing experience. So. Many. Stars.

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.

fsckboy•about 2 hours ago
there are tons of places in the US where it's dark enough you can see the milky way shining brilliantly, just not in the heavily populated areas. Washington, Oregon, Idaho Montana, California, Arizona, New Mexico, Maine, Vermont. even more places in Canada, Alaska, Norway...

You can see the milky way at any location with a sqm of 19 or higher. True darkness is sqm 22.

Nightfall by Isaac Asimov

ViktorRay•about 5 hours ago
For almost all of human history we lived with that true night sky.

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.

Darkness is one of the benefits of a high trust society.

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.

For most of my life, I never quite “got it” about the night sky. It was pretty, but not THAT different away from cities.

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.)

jamilton•about 2 hours ago
Huh, I just assumed everyone saw visual snow/noise in the dark, guess not. I was thinking of it like underexposed film grain.

I don't think I notice it that much with the night sky unless the stars are faint though.

ebb_earl_co•about 1 hour ago
I have this as well, and it showed up suddenly about 9 years ago. Trying to observe the sky ever since is distressing because I remember how my visual field used to be.

Where I grew up I could see the Milky Way overhead just by stepping outside of my house at night. Now when I go back to visit my hometown region two decades later, it’s mostly gone. Urban expansion and industrial installations have washed out the sky.

My city (low density suburb of Los Angeles) has outdoor lighting ordinances that spell out rules: all outdoor lighting must point downward, street lights are not allowed, holiday lights must be removed a week after New Years. There are also ordinances governing disputes--fees to get the inspector out at night, paperwork, etc.

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.

bushido•about 5 hours ago
A long time ago, I had the privilege of being in an area with zero lights. It wasn't a dark sky preserve officially, but it really was one. The night sky was mesmerizing.

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)

_caw•about 5 hours ago
One of the most effective ways you can personally help protect night sky is by installing downward facing lights with caps!

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.

I'm fortunate to now live under Bortle 3 skies. I got a telescope when I was a kid and stayed hooked on amateur astronomy for most of my life. But back then I lived in the city with Bortle 8 or 9 night skies...I kinda lost interest in the hobby.

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.

VCFundedGenYer•about 4 hours ago
It got 1000% worse when street lights went to LEDs. And in my area, they didn't even use warm colored LEDs - they are harsh bright white bulbs.

I miss the 70s/80s/90s era of street lights where they were warm and easy on the eyes.

SoftTalker•about 4 hours ago
Mercury vapor street lights are pretty harsh too. Sodium vapor lamps are a much more pleasant yellow-orange.
HeyLaughingBoy•about 5 hours ago
I live on a small farm a few miles from the closest town. It's not totally pitch dark, but on a clear night you can see the Milky Way and sometimes on my way back inside after doing evening chores, I'll just stand there staring up at the sky. It never gets old.

Does feel a bit eerie on moonless nights when the coyotes start howling though.

mont_tag•about 5 hours ago
As a stargazer, I've long been annoyed by one particularly bright satellite. It seems to have a cycle of 29 1/2 days and covers about 1/2 degree of arc.

OMG, it is so bright that it blots out all but the brightest stars. Something needs to be done about this.

Having access to dark skies doesn't mean you automatically appreciate them. I suspect this may be one reason we lost them so easily. As I child, I grew up at 5000+ ft with dark skies and the Milky Way was often visible. Funnily, no one seemed to be aware of it. Once I learned what it was (from a magazine), I pointed it out to a grown up and they dismissed it immediately as a cloud. Much later I learned that clouds from dark sites look dark, not light.

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.

I think actually we're forgetting how economically valuable light is and how much lighting at night improves human lives.

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.

DangitBobby•about 5 hours ago
Who is forgetting that? Complaining that I can't see the fucking stars doesn't mean I don't understand that having lights let's me see in the dark.
aikinai•about 2 hours ago
A lot of people are forgetting that. You see many anti-capitalist types claiming the world was paradise before we created technology and civilization. They have zero perspective and can't appreciate everything the modern world does for us.

That's actually what I thought this article would be about when I first read the title!

chaostheory•about 4 hours ago
You’re forgetting about how crime thrives in darkness. Better street lighting has helped reduced crime over the years. Better lighting has also reduced nighttime traffic accidents.

Wishing you could see the stars does not mean you’ve forgotten anything. I can wish a day was warmer and cooler. Two opposing things can be wished for, because they’re wishes.

> there are plenty of dark places just outside your city

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.

vigilantpuma•35 minutes ago
I think people really don’t realize what they’re missing out on. A really good illustration of this: https://www.lightpollutionmap.info/

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.

jaggederest•about 5 hours ago
The issue is that so much of night time lighting is wasteful and excessive, not that lighting doesn't enhance the world for humans.

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.

cadamsdotcom•about 4 hours ago
> 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!

I once saw motion activated streetlights that went from dim to bright as cars approached. It seemed very futuristic, and I wish a lot more places had them.

Light doesn't need to be aimed up into the sky to function. You need to spend more time in the world.

Good luck getting clear skies in Norway.

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.

VariousPrograms•about 5 hours ago
I know fellow stargazers who keep local dark spots secret for fear of drawing attention to them because they are that rare. Places that are dark and legal to be all night are even rarer (public boat ramps are a good place to look). It might be different on the US west coast where there's a lot of public land.

The article mentions Oregon east of the Cascades; I was going to say something if it didn't. So many amazing places to visit in that part of the world, and it is empty. It's one of the emptiest parts of the United States outside of Alaska.

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.

Story time! I used to live in Bahrain, which is an archipelago. When I was a kid my family and friends took a boat out to Umm Jaleed Island (nicknamed Bird Poop Island) for the night. Zero light pollution, we had tents but chose to stare up at the stars and get pinched by crabs, enjoying the quiet.

grew up in dubai in the 80s, and we went to a beach in fujairah once which had not just a wonderfully starry sky, but the most amazing bioluminescence in the ocean. don't think i've experienced both things together since then.
Blikkentrekker•about 5 hours ago
To be honest, I think this is a very unbalanced take. Better illumination stops crime and traffic accidents and I'm not willing to pay with human lives to see the stars obviously. The effect on wildlife and plants is certainly to be considered but this article is from the U.S.A. and I live in a country with far better illumination than that place and I've seen stories multiple times from foreigners who moved here and noticed that immediately, they stopped being afraid at night because the country is so well-lit and crime numbers are low as a consequence.

Human lives are a big price to pay to see some stars.
