The moon will appear to take bites out of the sun during a partial solar eclipse in the Northern Hemisphere. The eclipse will be visible Saturday across Europe, western Africa, eastern North America and northern Asia. The sun will shrink the most for the northeastern United States, Greenland and eastern Canada. During a partial solar eclipse, the sun is partly covered up and looks like a crescent. Experts warn against staring directly at the sun so make sure you have eclipse glasses handy. Another partial solar eclipse will occur in September at the bottom of the world.
