Cassini Spacecraft Marks 3 Years at Ringed World
partial view of Saturn with Earth seen as a dot Pale Blue Orb
Not since NASA's Voyager 1 spacecraft saw Earth as a pale blue dot from beyond the orbit of Neptune has our home planet been imaged in color from the outer solar system.

Here, Earth is captured in a natural color portrait made possible by the passing of Saturn directly in front of the sun, from Cassini's point of view. At the distance of Saturn's orbit, Earth is too narrowly separated from the sun for the spacecraft to safely point its cameras and other instruments toward Earth without protection from the sun's glare.
