The India at night during Diwali photo – what it really is

This pic seems to pop-up on Facebook every year at Diwali, i remember seeing it at least the past 3 years. You must have seen this one with the caption: India at night during Diwali: NASA

On the face of it this is easy to believe that it may be a picture of India at Diwali, it is colorful, seems to be bright etc. But then, why are Sri Lanka and Pakistan similarly lighted up?? A google image search throws up the real source.

From http://www.sciencephotogallery.co.uk/india_at_night_satellite_image/print/1705155.html

India at night, satellite view. This image is a composite showing the change in illumination over India from 1992-2003. Satellite data from 2003 is coloured red, 1998 is coloured green and 1992 is blue. The three data sets are composited to form the image. Nighttime lights on the map that are white are lights that were present throughout the entire period. Areas that are marked by red have only appeared in 2003. Areas coloured green and blue were only present in 1998 and 1992 respectively but are no longer visible. This image was created by the Defense Meteorological Satellite Program (DMSP), National Oceanic & Atmospheric Administration, USA.

The more you know.

Even if this isn’t a pic of it, there is no denying how good Diwali actually is in our country. Happy Diwali everyone,have fun.
