Image of Earth from Saturn

Nasa has released photos of the Earth and Moon taken by a spacecraft orbiting Saturn - nearly a billion miles away.

Our planet and its only satellite appear only as dots in the picture, which was taken by the Cassini spacecraft on 19 July.

Scientists wanted to pay homage to the "Pale Blue Dot" image captured by the Voyager 1 probe in 1990.

Earth can be seen in the bottom right part of the image beyond Saturn's majestic ring system
