An excellent, dense, and timely work by our colleagues Kocifaj, Bakos, and Kundracik, showing the negative effects of these orbital mirrors on the quality of the natural night. A must-read for scientists interested in the quantitative aspects of this emerging threat.

Atmospheric Light Pollution by Proposed Reflect Orbital Space Mirrors
ReflectOrbital is planning to launch a $18\times18$\,m mirror in space at a $\sim$600\,km altitude to illuminate a $2.5$\,km radius circular patch on Earth. The pilot satellite, called EARENDIL-1, is ...

Most recently (other than the book!), I wrote "Urban #Nightscapes and the #Anthropocene," published in the Urban and Environmental Dialogues series org by @nichecanada.bsky.social & @urbanhistorya.bsky.social

My UG coauthors & I analyzed #ALAN terminology in a White Paper, "Describing #ArtificialLight at #Night: Keywords in #LightPollution Literature and Why They Matter."
Had hoped to R&R or submit to new journal, but elder(s) care intervened.

Exposure to #ArtificialLight at #Night undoubtedly a factor
A 2021–2023 study in Spain of 1,899 people found night shift work increases long COVID risk by 88%.

Night shifts didn’t increase infection risk, suggesting disrupted circadian rhythms may affect how the body recovers from infection.
Night shift workers face 88% greater risk of long COVID, study suggests

The first piece I wrote about #ArtificialLight #ALAN #LightPollution #Darkness #Night was this one, "The Trouble with Darkness" (2017), which riffs off Cronon's famous Trouble with Wilderness to critically examine satellite imagery of light at night.

Has your observing site grown brighter—or darker?

Our 2025 light-pollution layer is live, based on the complete annual NOAA VIIRS dataset. Compare 2012–2025 for long-term change.

2025 is the latest completed annual layer; 2026 is an estimate.

I've been studying #ArtificialLight #lightpollution long enough now (!) that it's fasc to see how quickly activists, scientists & others mobilizing #lightpollution (among other reasons) to critique data centers.
That argument likely wouldn't be persuasive wo research over previous 2 decades.
