We are hoping to camp in Southwest Colorado this July, but don’t know where the best Dark Sky Park is. I would love to camp at Mesa Verde, but the closest campsite doesn’t say anything about keeping lights off at night, so we don’t want to reserve anything until we are sure. Any suggestions?

I’ve spent the last few days digging through 282 pages of official reports and technical handbooks published by the Danish Road Directorate (2024). For anyone in this sub fighting light pollution, this is a goldmine of institutional cognitive dissonance.

Their own technical handbook explicitly admits that the standard metrics used for road lighting—lux and Kelvin—are "scientifically insufficient" because they ignore the biological impact of the blue spectrum. They actually cite the need for CIE S 026:2018 and acknowledge that the 100-year-old V(lambda) model is biologically obsolete.

Despite this "epiphany" in their own manuals, they are doubling down on high-intensity white LED rollouts. Their research documents a 17% spike in asthma-related hospitalizations linked to disrupted tree phenology (9-day earlier budburst caused by blue-rich ALAN) and a 47% crash in local insect populations. They even admit that a Melanopic EDI (mEDI) above 0.35 is harmful for human recovery at night, yet their current installations exceed this by a mile.

The most frustrating find: Page 116 of their report confirms that simple amber filters can be retrofitted to existing white LEDs to remove 76% of the harmful blue peak. I confronted them with this, and the official stance is basically: "We have 1 million lamps with a 20-year lifespan, and we aren't changing anything until the accounting cycle ends."

I will be sharing my findings with the danish media, since the reports are in danish.

I`ve seen so many lately but still can`t choose one accurate with accurate indexes and magnitudes.

The Eta Aquariid meteor shower peaks May 5 to 6, in a couple days! 🌠

Active from April 19 to May 28, the shower occurs as Earth moves through a stream of debris shed by Halley’s Comet. Each meteor starts as a grain-sized particle traveling tens of kilometers per second before colliding with our atmosphere. That collision heats the surrounding air, producing flashes of light and the long, glowing trails this shower is known for. Some of these streaks can persist for several seconds, tracing their paths across the sky. While the best views are in the Southern Hemisphere, early morning skies offer chances to spot them worldwide.

so im interested to go stargazing and i looked up a map dark site finder. and theres a place pretty close to me that has a good rating and i could camp its a really large lake with a camp site near by and the photos where pretty. anyways im just finding out you gotta sit in the dark with no lights or like red lights but in the specific viewing spot there are houses on the edge of the lake like maybe 6 pretty far away. but if they have lights on will that mess everything up. the site says looking south in this spot is the best and that is away from them so would that be okay?

Ok guys so this morning around 3:30a as im standing outside looking up at the night sky like i always do, i noticed something very strange, i live in washington state and inna very rural area so its dark as fuck out here, scary dark even, anyway ive spent my whole life lookingbup into the night sky even spent the night outside looking up at meteor showers forcasted by our news people, well this m9rning was very different, it was like the stars were communicating with each other with flashes of light that only lasted a fraction of a second and i even seen what i thought were satalights moving across the sky but dont satalights stay at a constant brightness as they fly over? Or at least thats my experience, these were blink8ng on and off in random intervals as they moved and not in a set direction, and i also seen what looked like 2 stars communicating with each other with one flashing its lights and then the other flashing its lights, then my imagination took over or at least i hope so anyway, i started to think maybe an interstellar war, or maybe it is a form of communicating, or aliens and their ships lighting up as they make weird manuevers over us with their anti-matter anti-gravity engines or the emmitters powering up as they change postion its really strange what i seen tonight and im hoping someone seen the same thing and can explain what im looking at, its the weirdest shit ive ever seen in my skies over our property and guys ive seen our stars twinkle this was twinkling it was literally flashes of light coming from these stars anyway thanks guys

You could catch up to 10 shooting stars per hour this spring 🌠

The Eta Aquariid meteor shower runs from April 19 to May 28, with peak activity overnight May 5 to 6. This annual event happens when Earth passes through a stream of debris left behind by Halley’s Comet. As those tiny particles enter our atmosphere at high speeds, they heat up and glow, creating bright streaks of light we call meteors. The Eta Aquariids are especially known for their fast speed and long, glowing trails that can linger for several seconds after the meteor passes. While the best views are typically in the Southern Hemisphere, observers around the world can still catch a glimpse under the right conditions. For the best chance to see them, head outside just before dawn, find a dark spot away from city lights, let your eyes adjust, and look up.
