The Cassini
probe orbiting Saturn looks back at Earth, which appears as a lonely dot in the
night.
Not since Voyager
1’s portrait of Earth from Neptune – famously known as the Pale
Blue Dot – has our home planet been photographed from the outer Solar
System.
Cassini
used its wide-angle camera to snap this home portrait while at a distance of
about 930 million miles (1.5 billion kilometers) from Earth. The orbiter was
looking down on the Atlantis Ocean and the western coast of North Africa at the
time this shot was taken on Sept. 15, 2006.
A hint of
the Earth’s Moon is visible in a close look at the pale blue orb (inset). The satellite
appears as a dim protrusion to the upper left of Earth. Everything that is
humanity’s feats and failings is encompassed in just a few pixels seen by
Cassini’s camera eye.
The Earth
appears through the underside of Saturn’s rings, the main body of which appear
at right while the planet’s tenuous G ring reaches farther out. Saturn’s moon Enceladus
also is seen in this image on the left, its watery
plumes jetting material that eventually settles into the planet’s E ring.
Here’s a
few more links to views of Earth from afar by robotic probes and some humans:
