High Quality Content by WIKIPEDIA articles! National Dark-Sky Week (NDSW), held during the week of the new moon in April, is a week during which people worldwide turn out their lights in order to observe the beauty of the night sky without light pollution. This event was founded in 2003 by Jennifer Barlow of Midlothian, Virginia, and its popularity and participation increases every year. It has been endorsed by the International Dark-Sky Association, American Astronomical Society, the Astronomical League, and Sky & Telescope. Jennifer Barlow states, "The night sky is a gift of such tremendous beauty that should not be hidden under a blanket of wasted light. It should be visible so that future generations do not lose touch with the wonder of our universe."
