An astronaut captured a striking image of the Korean Peninsula from the International Space Station, revealing the stark contrast in nighttime illumination between North and South Korea.
South Korea, with its brightly lit cities including the sprawling Seoul metropolitan area, contrasts sharply with the near darkness of North Korea, aside from a few small clusters of light around Pyongyang and Yangdŏk. This photo not only highlights the differences in urban development and population between the two nations but also reflects the broader economic disparities, with South Korea being one of Asia’s leading economies.
Nighttime Lights Over Korea
An astronaut aboard the International Space Station took this photo of the Korean Peninsula showing the distribution of nighttime light. North Korea (extending beyond the top of this image) lies on the upper part of the peninsula and is almost devoid of nighttime lights. In contrast, South Korea lies on the lower part of the peninsula and exhibits night lights from many cities of different sizes. The seas on either side of the peninsula appear very dark in nighttime images, although cloudy areas reflect some light.
The largest and brightest cluster of urban lights is South Korea’s capital city, Seoul (population 9.67 million), located on the coast of the Yellow Sea. Only two small clusters of lights are easily visible in North Korea: the capital Pyongyang (population 3.16 million) and Yangdŏk in the country’s center.
The DMZ’s Light Line
Just north of Seoul, a thin line of lights crosses the peninsula from the Yellow Sea to the Sea of Japan, marking the demilitarized zone (DMZ) between North and South Korea. The DMZ border, established in 1953 by the United Nations, is about 4 kilometers (2.5 miles) wide and 250 kilometers (155 miles) long.
Economic Contrasts Revealed by City Lights
Differences in the brightness and expanse of city lights illustrates the distinction between the population sizes—South Korea with about 52 million people and North Korea with about 26 million—and between the extent of urban development in the two countries. Images of nighttime lights have also been used for studying economies and gross domestic product (GDP). Because of its dynamic industrial growth since the 1960s, South Korea has been termed one of Asia’s four “economic tigers” along with Singapore, Taiwan, and Hong Kong.
Astronaut photograph ISS070-E-80670 was acquired on January 24, 2024, with a Nikon D5 digital camera using a focal length of 24 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 70 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.

Well, if the USA continues to provoke China into a war over Taiwan, the south of the Korean peninsula might go dark as well. Because the Chinese are gonna leverage the Korean frontline, too. That ought to give the Yanks a pause.
North is better in this case! In total moonlight!
For a good sleep one needs darkness! Artificial world? Natural earth?
At least you can see the Milky Way and more than just a couple of stars.
Limit your energy/ resource consumption while I build my megayacht. That about right?
Gee isn’t democratic capitalism vastly different than communism.
