NASA [said](http://www.nasa.gov/content/goddard/satellite-sees-holiday-lights-brighten-cities/#.VJDhA97uWmD "undefined") Tuesday that data from a polar-orbiting satellite, in partnership with National Oceanic and Atmospheric Association, shows how cities’ nighttime lights change during the holiday season. From Black Friday until New Year’s, city lights are about 20 to 50% brighter than other times of the year. “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,” said Miguel Román, a research physical scientists at NASA Goddard who co-led the research. “These lighting patterns are tracking a national shared tradition.” ### PHOTOS: 20 Breathtaking Images of Earth From Space  Aleppo, Syria, May 26, 2013 – The Citadel of Aleppo – medieval fortified palace DigitalGlobe—Getty Images  Belfast, Northern Ireland, Nov. 3, 2013 – “Wish,” a large-scale art work DigitalGlobe—Getty Images  Utah, USA, April 22, 2013 – Colorado River DigitalGlobe—Getty Images  Cuanza River, Angola, April 28, 2013 – Cambambe Dam DigitalGlobe—Getty Images  Doha, Qatar, March 4, 2013 – Artificial island spanning nearly four million sq meters.

Scientists discovered some cities were lit more heavily throughout the region, which they attributed to political or cultural differences. “Even within majority Muslim populations, there are a lot of variations,” said Eleanor Stokes, a graduate fellow at NASA. “What we’ve seen is that these lighting patterns track cultural variation within the Middle East.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3637018/nasa-holiday-lights/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3637018/nasa-holiday-lights/"},"headline":"NASA Can See Holiday Lights From Space","datePublished":"2014-12-17T01:57:53.000Z","dateModified":"2026-05-11T05:06:38.261Z","description":"Cities are brighter during the holidays than any other time in the year","url":"https://time.com/3637018/nasa-holiday-lights/","keywords":["Space"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2bf76540fb1b75dc/69876f47428a9e256fcc61dc/nasa-christmas-holiday-lights.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Jack Linshi","jobTitle":null,"url":"https://time.com/author/jack-linshi/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt2bf76540fb1b75dc/69876f47428a9e256fcc61dc/nasa-christmas-holiday-lights.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"NASA Holiday Lights","caption":"NASA Holiday Lights","creditText":"NASA's Earth Observatory/Jesse Allen","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/space/","name":"Space"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3637018/nasa-holiday-lights/","name":"NASA Can See Holiday Lights From Space"}}]}] ```
