When you tell your neighbors that their"Frozen" Christmas displaycan be seen from space, you won't be lying.
Nighttime lights around major U.S. cities shine 20 to 50 percent brighter during Christmas and New Year's compared to the rest of the year, according to NASA.
Lights start getting brighter on Black Friday and continue through New Year's Day, saidMiguel Romn, a scientist from NASA's Goddard Space Flight Centre, Maryland.
Scientists at the centre examined light output from 70 U.S. cities in 2012 and 2013.
"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," Romn says in a video released by NASA. "We were surprised to see there is a vibrant increase in activity during the holidays, particularly around areas in the suburbs."
Lights in some Middle Eastern cities shine more than 50 percent brighter during Ramadan, according to NASA.
