Total eclipses don’t happen often in the US, which is why the one happening on Aug. 21, 2017 will be a big deal.
The last time there was a comparable eclipse in the US — one that, like this year’s will, crossed all the way from the Pacific to the Atlantic — was June 8, 1918. (That eclipse’s path stretched from Washington state to Florida, while the upcoming one will go from Oregon to South Carolina.)
