The city of Seoul (originally known as Hanyang) has been the capital of Korea for more than 600 years. This astronaut photograph illustrates the Seoul urban area at night. Major roadways and river courses (such as the Han River) are clearly outlined by street lights, while the brightest lights indicate the downtown urban core (center of image) and large industrial complexes. One such complex is located at the far left of the image and occupies an island in the Yellow Sea. Very dark regions in the image are mountains or large bodies of water.
