The image is actually as old as 2003 and was created by National Oceanic and Atmospheric Administration (NOAA) scientist, Chris Elvidge, to highlight population growth over time.
To those who gives NASA credits for this, here's your reply from NASA itself. "In reality, any extra light produced during Diwali is so subtle that it is likely imperceptible when observed from space."
This image is based on data collected by the VIIRS "day-night band", which detects light in a range of wavelengths from green to near-infrared, which was then artificially brightened to make the city lights easier to distinguish.
