Your Christmas Lights Are Visible From Space
Major cities get brighter during holidays, according to a new analysis of satellite images from NASA.
Three years ago, a satellite called Suomi NPP, a joint mission between NASA and the National Oceanic and Atmospheric Administration, began recording images of Earth from space.
Now a NASA-led team has decided to take a closer look at how the light Earth gives off changes over a year.
When we started looking at the data at night over the United States, we were expecting to see a lot of stability in the night time lights. We were surprised to see there is a vibrant increase in activity during the holidays, particularly around areas in the suburbs.
