Stunning pictures of Earth at night

Almost 40 years to the day after the Apollo 17 crew snapped the famed “blue marble” image of Earth floating in space on December 7, 1972, NASA unveiled 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 satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before. The cloud-free pictures, taken with a high-resolution visible and infrared imager aboard a NASA and National Oceanic and Atmospheric Administration satellite, capture the night lights of Earth in unprecedented detail. The so-called day-night band of the Visible Infrared Imaging Radiometer Suite, or VIIRS.

Stunning pictures of Earth at night
On November 12, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of southern Asia. The image is based on data collected by the VIIRS “day-night band,” which detects light in a range of wavelengths from green to near-infrared. The image has been brightened to make the city lights easier to distinguish.

A NASA Earth Observatory image released December 5, 2012 shows the area near the Korean Peninsula on the night of September 24, 2012. The image was acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The image is based on data collected by the VIIRS “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. The image has been brightened to make the city lights easier to distinguish. The wide-area image shows the Korean Peninsula, parts of China and Japan, the Yellow Sea, and the Sea of Japan.

A NASA handout released December 5, 2012 of a composite image of Asia and Australia at night, 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.

The image has been brightened to make the city lights easier to distinguish. This image was acquired near the time of the new Moon, and little moonlight was available to brighten land and water surfaces.
