Tiny Blue Dot
On July 19, NASA's robotic probe turned its gaze toward Saturn's majestic rings and a tiny pale-blue dot—a planet called Earth nearly 900 million miles (1.5 billion kilometers) away.
The Cassini orbiter snapped this historic image of its distant home world while on the far side of the giant ringed planet. (See more pictures of Earth from space.)
No surface features are visible since Earth takes up only a scant few pixels—however, its unique blue tinge caused by sunlight reflecting off our planet's oceans clearly shines through.
