NASA captured the image with the Visible Infrared Imaging Radiometer Suite. NASA says it can detect "faint light sources — in this case, the reflection of the full moon on the fresh snow."

The image also shows cloud streets over Lake Huron and Lake Superior. The parallel rows of clouds "are created by cold, dry air blowing over a lake and accumulating water vapor," NASA says.
