L’IA m’a informé pendant un mois. Elle ne s’en est pas toujours tenue aux faits
Dans un cas sur six, seulement, les nouvelles produites par des systèmes d’IA générative étaient fiables et accompagnées de sources vérifiables.

Here’s an example of how color and brightness can be used selectively for specific applications instead of painting everything in harsh white light. Street light are 2200K LED, pedestrian crossing is 4000K.

This picture, taken in January from the ISS, reveals a true transformation of Quebec’s nightscape, marked by the wide adoption of white LEDs in public and private lighting.

Not as pretty as a picture, but way more geek ;)
Here’s last night's lunar eclipse seen from the TESS-W photometers located in southern Quebec. These instruments measure the sky brightness by looking toward the zenith. (darkness increases the higher you go on the y-axis).

Wind farms and light pollution:
Medium-intensity turbine lights can be brighter than the brightest stars and planets on the night sky up to significant distances. This should be taken into account in environmental impact assessments.
