On a single day in August, the sun will disappear behind the moon, and sky watchers in the eclipse's path across 14 states from Oregon to South Carolina will witness a total solar eclipse.
The remarkable event occurs when the moon blocks the sun, turning daylight into twilight and leaving the sun's atmosphere -- or corona -- visible for a fleeting moment. Birds stop singing, and nocturnal animals get briefly confused by the appearance of darkness.
