NASA, shared a throwback Diwali picture, demonstrating how our country looked from space in the night when India was celebrating the festival in 2012.
Below is a photo of India seen from the sky on the night of Diwali, the wonderful festival of India.
On Diwali this year, as is ritual, the Internet’s favourite “NASA" Diwali photo has found its way into the pipelines of Twitter again. However, unlike the other years, people were more in the mood to take a few digs at the hoax rather than fall for it. The fake photo claims to show what India looks like from space on Diwali and has been debunked a number of times down the years. As per NASA, the photo is actually from the satellites of US Defense Meteorological Satellite Program (DMSP). It shows population growth over time, with the help of city lights. The white areas show city lights that were visible before 1992, and the blue, green and red ones show those that appeared in 1992, 1998 and 2003 respectively. The colour composite was created by NOAA scientist Chris Elvidge in 2003. Diwali lights are, in fact, too miniscule to be photographed from space.
It is Friday, November 5, and India is trying to get over the Diwali celebrations that made the entire country glow with grace yesterday. While the country is still recovering from the post-Diwali hangover, NASA shared a throwback picture this morning, demonstrating how our country looks from space in the night when we light the diyas (earthen lamps). As per NASA's description, the image was snapped in 2012 by the Visible Infrared Imaging Radiometer Suite (VIIRS) camera equipped on the Suomi NPP satellite, offering a stunning view of the South-Eastern nation.

Here's how NASA captured the image
As the VIIRS camera's full name suggests, it captured the image in infrared during the night. According to NASA, the 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. Since there is no shortage of multicoloured light during Diwali, the camera was easily able to pick up the lights having longer wavelengths. However, the image has been brightened to make the city lights easier to distinguish, says NASA.
This majestic image should not be mistaken for the one that circulates on social media every Diwali. For those brainstorming to remember the fake picture, take a look at the example below.
