NASA has recently unveiled a video showing the Christmas lights from space. The American space agency captured the video with the help of the Suomi National Polar-orbiting Partnership (Suomi NPP) weather satellite.

The satellite's data showed shifting changes in the patterns of lights that are responsible for illuminating the night sky over the holiday period.

Scientists at the Goddard Space Flight Center in Maryland and Yale University in Connecticut captured the images of light patterns across over 1200 cities for the period of two and a half years with the help of the satellite.

Researchers discovered that correlation of the increased lights happens perfectly with the holiday seasons for Ramadan in the Middle East and Christmas and New Year's Eve all over the world.

Miguel Roman, a physical scientist at NASA Goddard, said, "What's happening during the holidays is our patterns are changing. Those changes in behavior are changes in the locations of demand for energy services".

Researchers said that by understanding such seasonal shifts, they can ultimately know the level of carbon dioxide at the local level.

It is usually difficult to capture high resolution images during urban environments. But a fancy camera launched by the Suomi-NPP satellite, helps to capture images as it has low-lights sensors that could pick up wavelengths from green to infrared and make more intense images.

It is extremely sensitive and also allows every single pixel to get overexposed. It has the ability to pick the faintest signal and as well as very bright signals like volcanic magma on the Big Island of Hawaii, said Roman.

Almost two years back, NOAA used the camera for making composite images of a few months of lights at night.
