To the left, a greenish-orange band of atmospheric airglow hugs the Earth's limb, while the glow of impending dawn rises on the right. Below, the bright clusters of Chicago, Detroit, Indianapolis, Cincinnati, and Louisville stand out against the dark landscape.
A second shot offers a closer look at Chicago from a different night—March 1, 2024. This perspective makes it easier to spot subtle color variations in city lights, helping researchers identify different lighting technologies and track urban growth over time.
