The third annual Astronomy Photographer of the Year competition has received more than 700 spectacular pictures that were taken from different areas by amateur and professional photographers. The winners in four categories and three special awards of the competition will be announced on September 8, 2011. Before the important event, let's take a look at some entries competing for the prizes.
“Yosemite Falls Moonbow Star Trails” by Jeffrey Sullivan
This picture is taken as the light of the full moon creates a lunar rainbow in the mist of Yosemite Falls, Yosemite National Park, California on 11 July 2011. These rainbows only happen if the moon is full, the waterfall is flowing strongly enough to produce droplets of mist, and the two line up in the perfect position.

The picture is taken by photographer Jeffrey Sullivan
