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: <a href="https://en.wikipedia.org/wiki/Airglow" rel="nofollow">https://en.wikipedia.org/wiki/Airglow
I remember as a teenager going for a road trip, there was a stretch of the road that had no street lights about 100km away from the closest city. Looking at the side of the car I was surprised just how bright it gets when the moon is out and the sky is clear. You can totally walk around in the open without any extra lights.

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.
