In the year 1977, the space probe Voyager I and II were sent to the "space". Since then, both probes are travelling through the solar system, being almost in the limits right now. What is interesting is the fact that each Voyager has inside an Album, called "Sound of Earth". The album is made of Gold and has different kinds of songs and human sounds, that should represent the whole humanity. It is amazing that a NASA proyect, with mainly scientifical purpouses, also takes into account that kind of issues, about a possible Alien's Rendevouz. Carl Sagan was involved in the creation of that album. Sincerely, this topic about creating such an album with all the relevant information of the humanity is one of the most fascinating tasks that it has been ever done.

Another fascinating fact is that Voyager I is the most distant artifact, created by the humanity. They are still transmitting information, after 30 years... awesome. The picture shows the images that the Voyager I captured nearby Jupiter in the 80's (click on the image, is an animated GIF). Now Voyager I is almost out of the solar system, without no influence of the solar radiaton. But it carries an own battery, with radioactiv energy and will run out in 2020. After that, goodbye Voyager I! no more contact with it.
I strongly recommend you to read all the information related to Voyager probes in the Wikipedia. I took the information from there and does not make sense to copy everything here.
And please, do not forget to comment everything related to the Voyagers or the "Sound of Earth" album. I am really impressed about that mission.
