Last night when the Moon rose over Key Biscayne, Florida, "a strange phenomenon happened," reports onlooker Emanuele Colognato. "A number of dark beams seemed to be converging on the Moon's location in the east." He quickly photographed the scene through his apartment window:
"I call the photo Shadows in the Sky," says Colognato. That's a good name because the dark beams are shadows. As the Moon was rising in the east, the sun was setting in the west. Low-hanging clouds behind Colognato's back blocked the light of the setting sun and cast their shadows all the way across the sky. Perspective effects made the shadows appear to converge on the Moon. Experts call the dark beams anti-crepuscular rays; "Shadows in the Sky" works, too.
