A new view from NASA’s Cassini spacecraft shows planet Earth as a point of light between the icy rings of Saturn.
Image: Cassini Imaging Team.
The spacecraft captured the view on 13 April 2017 0541 UT. Cassini was 1.4 billion kilometres (870 million miles) away from Earth when the image was taken. Although far too small to be visible in the image, the part of Earth facing toward Cassini at the time was the southern Atlantic Ocean.

The rings visible here are the A ring (at top) with the Keeler and Encke gaps visible, and the F ring (at bottom). During this observation Cassini was looking toward the backlit rings, making a mosaic of multiple images, with the sun blocked by the disc of Saturn.
