- 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.
by mont_tag - 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.
by a1pulley - 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.
- 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.
by _caw - 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.
by AstroNutt - 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)
by bushido - 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.)
by thaeli - 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
