Seen from space, Berlin is still divided by street lighting. 30 years after the fall of the #BerlinWall, the former division between the East and West parts of the city is noticeable from the International @Space_Station. Can you spot the difference?

@Space_Station @astro_tim @ESA_de @esa @ESA_History @ISS_Research @cities4tnight @pmisson @ESA_EO The yellow lights correspond to East Berlin, where orange sodium lamps lit most of the streets today. The white glow comes from the brighter LED lamps in West Berlin. #BerlinWall30

@Space_Station @astro_tim @ESA_de @esa @ESA_History @ISS_Research @cities4tnight @pmisson @ESA_EO @astro_andre 🤔 What will your city look like from space in 30 years? #BerlinWall30

Look at more beautiful night-time pictures of cities to pass the time, and help #citizenscience project ‘Lost at night’ compare cities light pollution over time!
