Astronaut Chris Cassidy captured from ISS the dynamic shadow of the Moon cast over the Earth during Solar Ecplise. Solar eclipses occur when the moon, passing between Earth and the sun, is not quite close enough to our planet to obscure sunlight, leaving a part of the Sun visible. They happen every year or two, and can be seen from a narrow pathway across the planet.
