Chicago - Day and Night
Astronauts aboard the International Space Station took these day and nighttime photographs of Chicago. A network of rivers and canals, the Chicago River (arrows) runs through the center of the city.
In the nighttime image, the city lights outline almost every street and cross-street. The lights show us how people are distributed and allow us to see details that are often difficult to see in daytime images.
