Last weekend, the night sky was illuminated in New York by two twin beams of light shining upward from Lower Manhattan.
The 9/11 “Tribute in Light” memorial is in its ninth year. The rays, which are made up of more than 40 xenon light bulbs, are the strongest shafts of light ever projected from Earth into the night sky. Each year, they evoke the shape of the Twin Towers beginning at dusk on September 11 and fading with the dawn on September 12. Each year, they honor the victims of the terrorist attacks of 2001 and illuminate the sky as a silent, symbolic tribute.
The Municipal Art Society sponsors the display each year. For more information, see the New York Times article.
