The city of London, UK, at night captured by ESA astronaut Matthias Maurer.
Matthias posted these images to his social media on 26 March 2022 with the caption

I can often tell where we’re flying over during night passes by the shape and distribution of lights. Here we have London ??, and I think that’s The Hague ??. But, pretty as it is, there is a darker side to all this light. Excessive use of artificial light can actually have serious environmental consequences for humans, wildlife, and climate. That’s why I’m also looking forward to #EarthHour at 20:30 CET tonight. I’m going to try and spot the difference if I can. Will you switch off your lights? ??
