- Global light pollution has increased by at least 49% over 25 years. This figure only includes light visible via satellites, and scientists estimate the true increase may be significantly higher – up to 270% globally, and 400% in some regions. https://www.exeter.ac.uk/news/homepage/title_877183_en.html 14 comments science
- Study finds nowhere on Earth is safe from satellite light pollution. There appears to be nowhere left on Earth where astronomers can view the stars without light pollution from space junk and satellites, according to a new analysis. https://www.sciencemag.org/news/2021/03/study-finds-nowhere-earth-safe-satellite-light-pollution?utm_campaign=newsfromscience&utm_source=contractor&utm_medium=twitter 150 comments science
- NASA is asking astrophotographers and the public to help document light pollution from Starlink satellites amid growing concerns that a surge in LEO spacecraft will interfere with astronomical observations. This week, the Russian Academy of Sciences said they're bringing their concerns to the UN. https://www.discovermagazine.com/the-sciences/nasa-wants-you-to-photograph-starlink-satellites-with-your-smartphone 219 comments space
- We are losing the War on Light Pollution... The transition from sodium lights to LEDs, the so-called “lighting revolution”, was supposed to reduce energy consumption and bring back starry skies, but new satellite data indicate it’s not working out that way. http://www.skyandtelescope.com/astronomy-news/lost-led-revolution-light-pollution-increasing/ 76 comments space

- A German-led term reported Wednesday that light pollution is threatening darkness almost everywhere. Satellite observations during five Octobers show Earth’s artificially lit outdoor area grew by 2 percent a year from 2012 to 2016. So did nighttime brightness. https://www.apnews.com/5de588e62104434fb66e73973ff0c22e/good-night,-night:-light-pollution-increasing-around-globe 3 comments worldnews
- Satellite skyglow may mean light pollution is unavoidable. Even when satellites and other objects in orbit are too dim to be resolved by the naked eye, they collectively scatter enough light back into the atmosphere that it produces a diffuse glow similar to light pollution from cities. https://astronomy.com/news/2021/04/satellite-skyglow-may-mean-light-pollution-is-unavoidable 15 comments space
