There's going to be a lot of astronomical activity in the new year.  Beginning January 1st we'll have the chance to see planets we don't normally see.  A lunar eclipse will occur in February. More planet-viewing will come in spring, and some serious meteor-shower action is possible in fall.  But in late summer -- August, specifically -- something that hasn't happened since 1979 is coming.  A full-on solar eclipse visible from all ends of the United States will light up -- or rather, darken -- the sky.  The sun will disappear behind the shadow of the moon.  Get the scoop from USA Today.
