What if you want to experience how much night sky we have lost to light pollution?
The GLOBE at Night program is a 2-week international citizen-science campaign to raise public awareness of the impact of light pollution by encouraging everyone everywhere to measure local levels of night sky brightness and contribute observations online to a world map. Action can speak louder than words sometimes. The act of measuring night sky brightness often shows people how serious light pollution has become. The campaign ended in the northern hemisphere on April 4, but continues until April 6 in the southern hemisphere. For more information, visit Globe at Night.
Northern Hemisphere March 22 to April 4, 2011
