On August 1, 2008 a rare total solar eclipse will appear in the skies over parts of Canada, Greenland, Russia, Mongolia, and China. During this spectacular event, the moon will cross in front of the sun, completely blocking out the sun’s disk, and casting a shadow over part of the Earth. While only people in a small area of the world will be able to see the eclipse in person, viewers all across the globe can view the eclipse as it happens on NASA TV and www.nasa.gov.
