GLOBE at Night featured on Earth Science Picture of the Day
12 March 2010
A photo of the constellation Orion high above Portugal's noble Cape Espichel Lighthouse has been selected as today's Earth Science Picture of the Day. The picture illustrates GLOBE at Night.
GLOBE at Night is an annual 2-week campaign, this year running from 3 to 16 March. People all over the world record the brightness of their night sky by matching its appearance toward the constellation Orion with star maps of progressively fainter stars. They submit their measurements online and a few weeks later, organisers release a map of light-pollution levels worldwide.
