On July 19 2013, the Cassini spacecraft that is orbiting around Saturn, over a billion kilometres away, was turned around to snap a picture of the Earth! This is the photograph it took! The beautiful ringed planet looms large in the front of the picture, along with its entire ring system, and the Earth appears as a very distant ‘pale blue dot’. It might be a very small picture, but we're all in it, the billions of us on Earth.
