Earth in motion

Journalist and space enthusiast Vitaliy Egorov put together a series of images taken from Sep. 20 – 21 to create the animation above, which shows the Earth in motion. The satellite orbits once every 24 hours, so the face of the Earth seems to stay still as the day/night line (called the terminator) sweeps across it — you can also see sunglint, the reflection of the Sun off of water, moving across the ocean as well. Our planet, when seen the right way, is mesmerizing.
