Cassini Saturn photo: A view of Earth from 900 million miles away

Cassini Saturn photo: The images, from probes orbiting Mercury and Saturn, show Earth as a pale blue dot.

In this image from July 19th, the wide-angle camera on NASA's Cassini spacecraft has captured Saturn's rings and our planet Earth, plus its moon, in the same frame.

Earth, home to some seven billion people and at least some 9 million species, looks lonely. Or at least, it does seen at a distance of some 900 million miles.

NASA has released color and black-and-white images taken from its Cassini and MESSENGER probes orbiting Saturn and Mercury. Those images show Earth as just a dot, lost in the solar system’s gaping emptiness.

In the photographs from the Cassini spacecraft, Earth is seen from about 900 million miles afield, a bright blue dot just under Saturn’s mammoth yellow-brown rings. The moon appears like a small star, a humble white stipple in the surrounding darkness. 

And in the MESSENGER photos, Earth is pictured in a black-and-white image at a distance of about 61 million miles, from Mercury’s orbit. In that photo, Earth looks like a sparkling star – a bulb of white light quietly announcing itself from space. Together, the Earth and the moon are less than a pixel in the photograph, but have been overexposed to bloom with light.
