Cities at Night
citiesatnight.org
A citizen science project that invites volunteers to classify nighttime images of cities taken from the International Space Station to help map light pollution.
The site hosts thousands of astronaut photographs of cities at night, and visitors can contribute by identifying and classifying them. It bridges public participation with scientific research on light pollution. The visual archive alone is a compelling draw for those fascinated by urban landscapes from orbit.
