Everything Is Illuminated

Patterns of population density emerge in this composite image of the United States released by NASA on Wednesday, part of a global composite image captured from space by a NASA and National Oceanic and Atmospheric Administration (NOAA) satellite.

The cloud-free images show the glow of natural and artificial light in what a NASA press release calls the most detailed night images yet.

The images were unveiled during the American Geophysical Union conference in San Francisco.
