Christ­mas Lights Can Be Seen From Space By NASA Satel­lites

The Star (St. Lucia) - - LOCAL -

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.
