✨🔦 Light pollution, a marred tapestry in our night sky, Not a feature to laud, but a blight we cannot deny. No cause for festivity, no reason to cheer, But a glaring failure, a bug we should fear. 👹 It's an act of thoughtlessness, a careless blight, Against both human and nature's plight. An intrusion, stealing away the celestial view, Dimming the stars, changing the night's hue. 👎 It's not progress, but a careless mistake, A reckless path we should not take. In this glow, we lose more than we find, A reminder of the need for mankind to be kind. #lightpolution

#Astrophotography Photographer’s poem about modern #lightpolution ✨🔦 Amidst the night, LEDs flicker bright, Economical whispers in silent light. Saving energy, a dance so deft, Yet in their glow, the stars bereft. Their luminance spreads, a spectral thief, Dimming the cosmos, to astronomers' grief. A spectral pollution, unintended betrayal, Obscuring celestial tales, vast and regal. Alas, these bulbs, in haste they fade, Promises of longevity, swiftly betrayed. In their quick demise, a hidden cost, Old-fashioned bulbs, their value not lost. — Made with ChatGPT openAI.com, image by @xipteras 💡have a wonderfully filtered #LED night.🔭
This is the Centennial Light, the world's longest-lasting light bulb, burning since 1901. It is at 4550 East Avenue, Livermore, California and due to its longevity, the bulb has been noted by The Guinness Book of World Records. The Centennial Light was originally a 30-watt (or 60-watt) bulb, now very dim, emitting about the same light as a 4-watt nightlight. The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this technology. Its unusual longevity was first noticed in 1972 by reporter Mike Dunstan. The bulb is cared for by the Centennial Light Bulb Committee, a partnership of the Livermore-Pleasanton Fire Department, Livermore Heritage Guild, Lawrence Livermore National Laboratories, and Sandia National Laboratories.

You know the world is doomed, when you go outside at 2am to look at the sky and you can hear birds singing. Light pollution is fecking with nature, big time.#lightpolution #birds #wildlife
