On August 21st 2017, the darkest part of the Moon’s shadow traced a path across the continental United States. Those that fell in the path of that shadow could see the Moon completely cover the Sun from their point of view. During this ephemeral moment, the solar corona—the Sun’s faint, superheated, outermost layer of atmosphere—became uniquely visible to the human eye, sprawling outward from the darkened disk. This is an artistic representation of that event taken from Block 4186869, which corresponds with the time when parts of Missouri and Illinois were experiencing the total solar eclipse on this day.
