On July 19, 2013, while exploring Saturn, NASAs Cassini spacecraft took this image of Earth from a distance of about 898 million miles away.
This is only the third-ever image of Earth from the outer solar system, because normally photographing the Earth from such a distance requires turning the lens on the sun, and exposing it to damage; in this case, Saturn blocked the sun from Cassini's direct view, while the planet's "icy, dusty rings" (in NASA's phrase) caught the glow.
The image calls to mind the famous "pale blue dot" photograph from the 1990 Voyager mission, which poet-astronomer Carl Sagan described memorably:
From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there on a mote of dust suspended in a sunbeam.
