Nearly everyone has seen iconic photographs of Earth shot by astronauts in orbit or on the surface of the moon. But every now and then NASA releases an image that helps us all take an even greater step back to see the big picture of our place in the universe. While headed off to distant moons and planets, robotic spacecraft are occasionally commanded to look back toward home. It's tricky business because light from the sun can destroy cameras designed to observe in low-light conditions. From one million miles away, or about four times the distance from Earth to the moon, the planet's bright blue disk fills the frame. However, beyond the inner solar system, a few hundred million miles out, Earth is a mere pixel or two amidst the darkness of space. Step through the video and images for views of our planet at progressively farther distances.
