NASA has captured many images of the landscape bathed in bright sunlight, but images of the planet shrouded in darkness may be just as beautiful,media bGR reported. In a new image display on NASA’s website, the agency processes images of the Earth’s “night side” captured by the Suomi NPP satellite, which was launched in 2011.
Satellite-captured images are combined with existing images of the Earth to accurately show what night is like as they descend on the Americas. The final composition is stunning.
In addition, NASA provides some technical insights:
Suomi’s Visible Infrared Imaging Radiometer Kit (VIIRS) “Day and Night Band” gives this photo an amazing nighttime view. VIIRS detects light at various wavelengths from green to near-infrared and uses filtration techniques to observe dim signals such as city lights, aurora, wildfires, and reflected moonlight. In this case, aurora, wildfires, and other stray lights have been removed to highlight the city’s lights.
NASA is using the photo as an opportunity to promote its latest e-book, which contains a wealth of photos and written information explaining the tools NASA uses to observe different regions of the Planet.
The e-book is completely free and accessible directly through NASA’s website, and includes about 200 pages of content, including stunning images of Earth and an introduction to human impact.
