The image above is assembled from 1400 people waving at the Cassini spacecraft, which has been in orbit around Saturn since 2004. On July 19, the orbiter turned back and snapped a photo of the home planet it would never see again. NASA thought it was only fair that we wave back.
The images come from people in 40 countries and 30 states. And it's not too shabby as a whimsical reminders that for all the lines we draw between us on Earth, we're all part of the same thing when you're looking down from space. [NASA]
