Satellite imagery reveals increasing volatility in human night-time activity: https://www.nature.com/articles/s41586-026-10260-w -> Satellites capture the glowing pulse of human civilization: https://news.rub.de/english/press-releases/2026-04-08-geography-satellites-capture-glowing-pulse-human-civilization (my contribution to the 2nd image there was rotating - not far enough - and cropping it :-). #ALAN #LightPollution #VIIRS

Hmm, let's see what the lights look like in Cuba (December vs. February 12, 2026) #remoteimaging #viirs

“This tool visualizes near real-time (NRT) satellite-based fire perimeters, active portions of fire perimeters (fire lines), and active fire pixel detections for the current year.
Use the bottom panel to select different date ranges or subset fires by size, duration, or intensity. Click on an individual fire to visualize the time series of fire growth every 12 hours and create video outputs in GIF or WebM formats.
These fire tracking data are from the Fire Event Data Suite (FEDS) algorithm. Find out more:
• FEDS data source documentation
• OpenVEDA documentation
• Earthdata VEDA dashboard..."

Acabo de actualizar mi dataset sobre contaminación lumínica nocturna global generado con mi herramienta radiance-geojson (https://codeberg.org/imigueldiaz/radiance-geojson). Contiene archivos JSON (.json.gz) y un dump completo en PostGIS (restaurada ocupa 27GB, con casi 140 millones de puntos georreferenciados), con datos de radiancia, brillo del cielo y clasificación Bortle para 173 países a 0.5 km de resolución. Basado en imágenes VIIRS de Earth Observation Group, Colorado School of Mines.

Puedes descargarlo gratis desde: https://archive.org/details/radiance-geojson-data-2025

Ideal para análisis geoespaciales, ambientales y astronómicos, en mi caso lo usaré para astrofotografía si me da la vida. Licencia CC BY 4.0.

Apparently, between mid-August and now the endpoint we were using to download #VIIRS satellite data from #NASA has disappeared.

I am trying really, really, really, hard not to discuss political issues in this account, because I would like to make this one all about science, but sheesh.

In order to fully understand how #LightPollution affects our world, we need to know how much of it is in which places. Divergent results from different measurement methods present some tension, but recent research suggests a way forward.
