“If we lose these skies, we’re not just losing them for ourselves, all of humanity loses them. There’s no replacement site. That’s why it should matter so much — not just to me, to #Chile or the astronomical community, but to everyone.”

Pittsburgh "plans to dim the new lights between 11 p.m. and 4 a.m., which will save energy and money, and, according to the city, cause less harm to migratory birds, urban wildlife and humans."

„When millions of people turn off their lights for Earth Hour each year, something remarkable happens in the night sky above cities. New research from Hong Kong published in Scientific Reports shows that just a small number of decorative buildings and advertising boards can dramatically brighten the entire urban night sky and when they go dark, the sky becomes up to 50% darker.“

New instance, new #introduction post!

The time has come for me to move on to this instance much more in line with my interests.
Gone are the many messages that I posted over the last couple of years, but I'm happy to have found a new, more like-minded community to compensate for this migration side effect.

You will find me sharing mostly #LandscapePhotography, #NightPhotography, #MacroPhotography and #BirdPhotography.

I am also interested in #astronomy and #LightPollution.

Below are a few of my landscape photos.

In 2021, hundreds of citizen scientists walked a distance of 600 km, counting up and classifying all of the outdoor lights they could see while they did it. The results of their observations have just been published in the journal Nature Cities: https://www.nature.com/articles/s44284-025-00239-5

Find out why they did it, and what they found out in this thread 👇
