Two of NASA's interplanetary spacecraft, Cassini and MESSENGER, photographed Earth on July 19, 2013. NASA has just released color and black-and-white images of Earth and our Moon which were taken from millions of miles away. The color images were taken by NASA's Cassini spacecraft through the rings of Saturn using Cassini's highest-resolution camera. Since this image was taken from nearly 900 million miles away, the Earth and our Moon look like small blue and white dots. MESSENGER captured the black-and-white image from a distance of 61 million miles away in Mercury's orbit. The Earth and our Moon are smaller than a pixel in this image but they are very large due to overexposure.
