The Earth never sleeps
These stunning images depict countries, continents at night, how beautiful our planet Earth is. Thus, the first photograph depicts the European continent at night. Looking at these breathtaking images it becomes clear where the most of the population concentrates. NASA satellite technology from the Suomi NPP satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite detects light in a range of wavelengths. In particular, from green to near-infrared and uses filtering techniques to observe dim signals. For example, city lights, gas flares, auroras, wildfires, and reflected moonlight.
