Most urban areas around the world might complain about a lack of lighting at night, but in Spain a coalition of astronomers, environmentalists and ordinary star lovers have pressured some 20 cities and towns to reduce night lighting because stars have all but vanished. According to the group, Madrid and Barcelona have six times more lighting than necessary for safety and comfort, and more than 30 percent of the lighting is wasted. Look for many cities to tone down the lighting in the next year.
