2017 Solar Eclipse

Taken by an astronaut on the International Space Station, this photograph reveals a dark shadow over the continental United States. The dark shadow is the Moon’s shadow, cast during the 2017 Solar Eclipse.
A Solar Eclipse is when the Moon passes between the Sun and the Earth, making the Moon cast a shadow on the Earth. The shadow from this year’s eclipse moved across 14 U. S. states, starting in Oregon and ending in South Carolina.
