Pretty picture: Looking backward

Posted by Emily Lakdawalla on 2013/07/23 05:03 CDT | 15 comments

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. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

Pretty picture: A study in ringlight

Posted by Emily Lakdawalla on 2012/03/08 02:27 CST

Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background.

Nearly everything in this picture is lit by light that has not arrived directly from the Sun.
