Did you know that Voyager is now 100 times further away from us than the sun? That is incredible. A human made object thrown deep into space for thirty years and still going. The BBC did a lovely piece on it with a wonderfully enthusiastic scientist.
You can find out about the mission from the NASA site and the iconic gold disc that is full of the images, sounds and texts that were chosen to represent our world. Interesting, all the images are copyrighted, so no room for creative commons licensing in space. Aliens beware.
