The next few nights celebrate the stars! The International Dark Sky Week (April 5-11, 2013) is a worldwide event against light pollution and going on now!
Light pollution is a growing problem: “Not only does it have detrimental effects on our views of the night sky, but it also disrupts the natural environment, wastes energy, and has the potential to cause health problems.”
The goals of IDSW are to appreciate the beauty of the night sky and to raise awareness of how poor-quality lighting creates light pollution.
