NASA ’s Suomi NPP artificial satellite was able to snaffle this beautiful look-alike of the United States of America at Nox because of a unexampled infrared sensor on the satellite . The detector is able to observe natural light versus man - made light at highly high resolution . That ’s how you get this perfect range of Earth at night .
Wired writes :
The Visible Infrared Imaging Radiometer Suite has a “ day - Nox band ” that can observe natural and man - made light with unprecedented closure and lucidness . It can conclude everything from the nocturnal glow of the atmosphere to the lightness of a single boat at ocean . It can detect Aurora , wildfires , the reflection of moonshine and star light off cloud and sparkler and the ignitor alongside highways . The detector has six time better spatial resolution and 250 times better solution of lighting levels than anything that came before it .
What ’s interesting is that the pictures from the Suomi planet are useable to the public , giving most citizenry the exonerated look of Earth at night ever . Before , the Air Forced had nighttime sattelites in romp but most of the data was assort and not well-nigh as clear as the image above . To see more angles that the Suomi satellite was able to take , tally it outhere[Wired ]
