Cassini image of Earth in Saturn's rings

Tweet I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home.  I don’t think it encouraged a proper sense of perspective…  But the resultant image is stunning. [Image Credit: NASA/JPL-Caltech/Space Science Institute] It’s not the first time Cassini has looked home.  […] more »
