Summary: There’s a total solar eclipse happening on August 21, 2017, and for the first time in nearly a hundred years, the Moon’s unabashed Sun-blocking power will be visible from much of the continental U.S. (though certain locations will of course have a better vantage point than others). Warning: don’t look directly at it with your naked eyes—instead, use certified eclipse glasses or the pinhole method described here. In the U.S.
