NASA Images Show Holiday Lights Brightening The Night Across Globe

New stunning images from NASA show how holiday lights brighten the nights of cities all over the globe.

U.S. cities, particularly Baltimore, Washington, D.C., Richmond, Virginia, plus Houston and Dallas really show off their Christmas cheer at night, become 30 to 50% brighter during the Christmas holidays. Atlanta looks like its own city of lights during the holidays, too.
