Right: A Reuters picture captures a plane flying in front of the world's first partial solar eclipse of 2011 in Aachen, western Germany. Wintry skies darkened over Switzerland in morning, but Romanians were treated to a pinkish ethereal light and Swedes to a beautiful sunrise, as a partial solar eclipse that began over the Mideast extended across much of Europe. A solar eclipse happens when the moon lines up between the sun and the Earth, casting a lunar shadow on the Earth's surface and obscuring the solar disk. During a partial solar eclipse, only part of the sun is blotted out. __
