This image shows the very obvious border between North Korea and South Korea.
The lights of Seoul, South Korea's capital, are mixed among many other city lights. The only bright spot in North Korea is its capital, Pyongyang.
Also visible is the border between North Korea and China, as well as other parts of China just across the Yellow Sea.
How come the border between North and South Korea is so visibly pronounced, especially since borders are typically harder to spot from space?
Why is Pyongyang the only bright spot in North Korea, whereas South Korea and China have plenty of lights visible at night?
