Thousands of scientists, space enthusiasts and sun worshipers flocked to cities and towns along the path of the total solar eclipse that streaked across the United States.
The eclipse began Monday in the Northwest, starting in Oregon and charting a path of totality through Wyoming, Idaho, Nebraska, Missouri, Tennessee and South Carolina. A partial eclipse could be seen throughout the rest of the U.S.
The following are just some of the highlights of the day.
