Christmas Lights Can Be Seen From Space By NASA Satellites
It’s not just your neighbours who can see your Christmas lights. The combined effect of holiday lights in cities and suburbs is so powerful that the difference from normal lighting conditions can be detected from space. NASA reports that satellite images show certain cities shine between 20 percent and 30 percent brighter during the holiday season. And out in the suburbs, some areas shine as much as 50 percent brighter.
“It’s a near ubiquitous signal. Despite being ethnically and religiously diverse, we found that the U.S. experiences a holiday increase that is present across most urban communities,” Miguel Roman, a research physical scientist at NASA Goddard and one of the leaders of the study said in a news release.
