Credit: NASA Earth Observatory/NOAA NGDC (Phys.org) -- Scientists
unveiled today an unprecedented new look at our planet at night.
A global composite image, constructed using cloud-free night images
from a new NASA and National Oceanic and Atmospheric Administration
(NOAA) satellite, shows the glow of natural and human-built phenomena
across the planet in greater detail than ever before.

This image of the continental United States at night is a composite
assembled from data acquired by the Suomi NPP satellite in April and
October 2012.
The image was made possible by the 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.
