Given the harmful effects of light pollution, a pair of astronomers has coined a new term to help focus efforts to combat it. Their term, as reported in a brief paper in the preprint database arXiv and a letter to the journal Science, is "noctalgia." In general, it means "sky grief," and it captures the collective pain we are experiencing as we continue to lose access to the night sky.

There was a NASA lady on StarTalk recently talking about how there's something like 360,000 more satellites planned/approved to go into orbit and it's going to completely erase the night sky. We're at something like 7700 currently.

We are slowly turning ourselves into Krikkit.

Soon as we invented the little green piece of paper it was all downhill from there

[-] DeadNinja@lemmy.world 3 points 2 years ago

If you have seen that StarTalk episode, do you remember what Neil DeGrasse Tyson's response to that? He seems like good people..

It’s shocking how many lights are left on during the night in a city or a built up area. Does a big box store need to keep its logo lit all night? We’re so desperate to shut out the beauty of the planet and blind ourselves with human made ugliness.

[-] XeroxCool@lemmy.world 42 points 2 years ago

It's frustrating how many people have security lights aimed wrong. They're often aimed high, wasting light to the sky, and they're often mounted low, blinding you walking into your own home and leaving you vulnerable.

[-] ItsComplicated@sh.itjust.works 15 points 2 years ago

Or those backyard street lights bright enough an airplane could land with!

[-] XeroxCool@lemmy.world 14 points 2 years ago

The sad irony is that with no around to monitor the property, these [in]security lights are often just providing light to any thieves. If you see flashlights bobbing in a yard, it's suspicious. If you see someone walking through someone else's yard, it might just be the owner. If you light the yard and you aren't around to look, do the thieves make a sound?

[-] BURN@lemmy.world 16 points 2 years ago

TBH if I’m out at night I’d much prefer it to be bright and lit up in the city. If the city is dark and quiet at night it feels more unsafe to residents.

Not saying it’s right, but it makes sense

[-] pgp@sh.itjust.works 16 points 2 years ago

The city can be lit and bright and keep the light pollution to a low. If only street lights were on, and these were directed towards the ground.

[-] Poggervania@kbin.social 14 points 2 years ago

Additionally, you’d use a different kind of light for street lights. On the island of Hawaii, that island specifically has a light pollution law that mandates all street lights have to use an orange light bulb, and they can only be in certain places. It’s amazing because you can see so many stars in the night sky.

If city lights are gonna be on 24/7, we should start to see if we can get traction for reduced brightness and installing less light polluting lights.

[-] carbrewr84@kbin.social 12 points 2 years ago

It's technically not orange light bulbs they have to use, it's a specific lamp style called 'low pressure sodium'

Here's an article that explains the reasoning behind Hawaii's lighting sources and the regulations:

[-] Zak@lemmy.world 7 points 2 years ago

That site is claiming that phosphor-converted amber LEDs provide all the benefits of low-pressure sodium. They do not; one of the benefits of LPS is that astronomers have a very narrow frequency band to filter out, while PC amber is much wider. Monochromatic amber LEDs are more comparable to LPS.

Or the big advertisement screens. I get the need for street lights but they also don't have to be the most brightest super white LEDs that exist either. Nowadays I literally can't even tell whether it is cloudy or not, because the sky is just this mushy grey noise. And the sad thing is that I still remember the night sky from a couple decades ago when cities weren't quite as bright. Now you can be lucky to see the little dim flickering of the brightest odd stars every now and then.

[-] Gerbler@lemmy.ml 5 points 2 years ago

the sky is just this mushy grey noise

You might even say it's the colour of television, tuned to a dead channel

[-] FordBeeblebrox@lemmy.world 9 points 2 years ago

As someone currently living across the road from a strip mall with a dozen various businesses…NO YOU DO NOT NEED TO KEEP THE LIGHTS ON 24/7

[-] BoilingTea@lemmy.world 22 points 2 years ago

Reminds me of how we sometimes export light pollution. When I first got to Afghanistan I thought I would be able to see the stars being in the middle of a desert. That idea was quickly made harder to accomplish by the massive light pollution coming from camp leatherneck which, along with the moon dust perpetually floating mid air, killed any chance to see the stars clearly for miles around. Base turned a patch of desert into a sprawling light factory in just a few years.

[-] TheMadnessKing@lemdro.id 3 points 2 years ago

Srsly, a few weeks ago, I though to take walk at 2 AM, and TF. The sky was literally bright as it was 6PM. Ruined the entire feel for me.

[-] ChaoticEntropy@feddit.uk 3 points 2 years ago

Going to see a decent patch of sky basically requires a vacation to go somewhere else.

[-] LaunchesKayaks@lemmy.world 15 points 2 years ago

I live in the darkest part of my town. When my porch light burned out, I decided to not replace it because sometimes I can see stars at night.

[-] morrowind@lemmy.ml 11 points 2 years ago

Why is every other website being bought by future inc and using that same layout

[-] cheese_greater@lemmy.world 10 points 2 years ago

Try in a small town. Seriously, tho villages are better. Go in the backroads, you'll have plenty of sky and stars to get lost in.

[-] BolexForSoup@kbin.social 25 points 2 years ago

You'd be surprised how much "bleeding" there is. You also can't scope in certain directions because of even really far off cities. You're often forced into a specific cone.

[-] cheese_greater@lemmy.world 4 points 2 years ago

Perfection is the enemy of "good-enough and be able to experience in this lifetime"

[-] FlyingSquid@lemmy.world 14 points 2 years ago

Only in the most remote deserts, wilderness areas and oceans can you find a sky as dark as our ancestors knew them.

The article is about how there's less of it over time. Areas that were once nice (ex. Great views over the water or over a nice field) no longer work because of nearby light pollution.

[-] Sanctus@lemmy.world 9 points 2 years ago

There are few places left on Earth to see an unpolluted night sky. Definitely nowhere near civilization. On top of that, light pollution still drowns out dimmer objects permanently. We are blinding ourselves globally. To our ancestors the sky was a living light show. Its no mystery why they thought gods lived there.

[-] DarkThoughts@kbin.social 3 points 2 years ago

In densely populated areas you have to move quite far out to find such places. Like, check a light pollution map and then scroll into central Europe, like around the Netherlands and western Germany. It's all just a big red blob.

[-] FluffyPotato@lemm.ee 8 points 2 years ago

In my parents farm the night sky is perfectly visible. They live far from any town and there are no lights you can't just turn off so sometimes I just look at the sky when I'm visiting.

Plenty of places like this still in my country thankfully.

[-] negativeyoda@lemmy.world 8 points 2 years ago

I've always lived in cities and didn't see the milky way until I was in my 30s.

Anyhow, I took my kid camping last weekend and she couldn't believe how many stars there were. We were both enjoying it but then the string of SpaceX satellites went by and kind of ruined the moment

[-] havokdj@lemmy.world 4 points 2 years ago

I laughed at that last part. I am sorry that happened to you but it is pretty funny.

[-] PersnickityPenguin@lemm.ee 3 points 2 years ago* (last edited 2 years ago)

We were just up in the mountains last weekend, it was by far the best stargazing I have ever experienced in my 40 years. I could see the Andromeda galaxy with the naked eye.

Anyway, I counted over 15 satellites during the 2 hours we were outside, as well as 2 very bright meteors. Plus we saw the international space station and an iridium flare.

Elon ruins everything he touches

[-] nnullzz@lemmy.world 6 points 2 years ago

What a simple, great word to describe it.

[-] Kbobabob@lemmy.world 6 points 2 years ago

The part that wasn't in the title:

astronomers have invented a new term to describe the pain associated with this loss: "noctalgia," meaning "sky grief."

[-] FlashZordon@lemmy.world 6 points 2 years ago

Lived in the city for a few years before moving back to my rural hometown. The night sky without any light pollution was definitely an underrated thing I didn't realize I missed.

[-] Skua@kbin.social 5 points 2 years ago

This feels like it comes from the Dictionary of Obscure Sorrows. It'd fit well
