Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring.

New names for Pluto's little moons Kerberos and Styx; and a new moon for Neptune

Posted by Emily Lakdawalla on 2013/07/15 01:37 CDT | 4 comments
