Monday's total eclipse will cast a shadow that will race through 14 states, entering near Lincoln City, Oregon, at 1:16 p.m. EDT, moving diagonally across the heartland and then exiting near Charleston, South Carolina, at 2:47 p.m. EDT. The path will cut 2,600 miles (4,200 kilometers) across the land and will be just 60 to 70 miles (96 kilometers to 113 kilometers) wide.

The U.S. has not seen a total solar eclipse since 1979. The latest "Great American Eclipse" is arriving on Monday afternoon and there may be a few who still have unanswered question. How do I make my own eclipse glass? When I be able to view the eclipse?

The next total solar eclipse in the U.S. will be in 2024. The next coast-to-coast one will not be until 2045.
