Astronaut images taken about 13 years apart indicate that the colour of city night lights is shifting globally. The photos show changes in the appearance of urban lighting, moving from more yellow-leaning tones toward whiter light across many cities.
The coverage frames the change as a large-scale visual trend visible from space, suggesting updates in lighting technology and patterns of use over time. While the reports focus on the colour difference visible in satellite or astronaut perspectives, they do not provide detailed attribution for the specific drivers in the materials shared, such as what share of lights were replaced, where the changes are strongest, or how quickly they occurred. The overall angle is that the images offer a comparative view of how urban illumination evolves over more than a decade.
Across outlets, the core point is consistent: comparing the two time-separated images reveals a noticeable transition in the colour of night-time city glow.
