New Delhi, April 19: The American space agency NASA has released a new global map based on satellite imagery. This map illustrates how nighttime lights on Earth have changed from 2014 to 2022. Scientists at NASA were astonished to see the brightness of Bihar and Uttar Pradesh in India. The map reflects the development that has taken place in both states over the past nine years.
NASA scientists analyzed 1.6 million satellite images collected every night over nine years to capture Earth’s nighttime view. The results revealed an increase in nighttime light levels in northern India, particularly in Uttar Pradesh and Bihar, due to urban development.
Led by Tian Li and Jie Zhu from the University of Connecticut, the scientists employed a new algorithm to analyze images taken by the Visible Infrared Imaging Radiometer Suite (VIIRS). Areas glowing in gold indicate brighter lights at night, while those in purple show less illumination.
Regions in India, China, the Middle East, and Central America predominantly appear golden, while the western United States shows golden areas, and the east displays more purple and white. Europe, on the other hand, is mostly purple, indicating a decrease in nighttime illumination during this period.
NASA shared the image with a note stating, “The Earth is not just getting brighter; due to changes in nighttime lighting, some places are becoming luminous while others are dimming. This conclusion is based on the analysis of 1.16 million NASA satellite images taken every night over nine years.”
Sanjay Jha, a Member of Parliament from the Janata Dal (United), reposted NASA’s post, expressing, “When you zoom in on India, you will be pleased to see that Bihar shines brighter than many other places. The good governance of Nitish Kumar over two decades has led to this significant leap, for which future generations will always be grateful. Great job, NASA!”
