Washington, April 13: Twinkle twinkle Little Star, How I wonder what you are? Drowned in the shining nights, Look there India seems so Bright. Yes, NASA released the fresh image of our Earth at night which is termed as ‘Night Lights’. NASA scientists have released the new global map of Earth at night since 2012.The night time image of our Earth also dubbed as ‘Black Marble’ provides researchers with a unique perspective of human activities around the globe. By doing this, researchers can investigate how and why cities expand, monitor light intensity to estimate energy use and economic activity, and aid in disaster response in near-real time.
Satellite images of Earth at night known as "night lights" are seen as a tool for fundamental research for nearly 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness.
How did the scientist click these pictures?
The data on Earth at night comes from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument on the Suomi National Polar-orbiting Partnership satellite, jointly managed by NASA and the National Oceanic and Atmospheric Administration (NOAA).
VIIRS captures visible and infrared light, allowing researchers to glimpse the Earth as it looks to astronauts peering out of the International Space Station. The new map is a composite of data collected in 2016, and it took several months of processing to filter out clouds, moonlight, airglow, and other interfering features to create the global image. In the coming months, our scientists will release daily nighttime lights data at even finer resolutions for the first time.
Following are the images which were revealed by the NASA scientist of different parts:
