Animated GIF showing the Moons shadow crossing the earth during the partial solar eclipse on Oct 23rd 2014.

I love this animated GIF produced by NASA. It really makes it clear to me how the shadow of the moon falls across the earth during the eclipse.

Animated GIF showing the partial eclipse

During the late afternoon of Oct. 23, 2014, a partial solar eclipse will be visible from much of North America before sundown. However, it is never safe to look at the sun with the naked eye.
