This NASA image shows the United States at night. The image was made possible by the new satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires, and reflected moonlight.

A NASA Earth Observatory image shows the area near the Nile River valley and delta on the night of October. The image was acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. This image was acquired near the time of the new Moon, and little moonlight was available to brighten land and water surfaces. (Reuters/ NASA)
