It is the first coast-to-coast total eclipse since 1918. Total solar eclipses occur somewhere on Earth every year or so, but most cast their shadow over oceans or remote land. The last total eclipse over part of the contiguous U.S. was in 1979. All of North America will experience a partial eclipse, though the difference between a full and partial eclipse is "literally the difference between night and day," said astronomer Rick Fienberg of the American Astronomical Society. And during a total eclipse, the temperature drops and the horizon is ringed by the colors of sunset.
