A copy of the gold plate, sent into space by NASA in 1977 via the Voyager 1 and Voyager 2 probes, has been offered for sale.
The copy was owned by astronomer Carl Sagan.
It is a kind of time capsule that should give the one who finds it in the universe a kind of insight into the story of people, or earthly race.
On the golden plate there were 115 photographs and various natural sounds such as waves, wind, thunder...
In addition, the record features a selection of music from around the world and different eras in human history, all recorded in 59 languages.
On the plaque itself is written a greeting message from then US President Jimmy Carter and UN Secretary General Kurt Waldheim.
The panel is placed in a protective aluminium cover on which the images explain how to start the board and listen to its contents.
When voyager 1 and Voyager 2 spacecraft left the solar system, they found themselves in empty space.
It is predicted that, due to the speed at which they fly, it will be forty thousand years before they approach any other planetary system.
A copy of that gold plate will be offered by the famous auction house "Sotheby's", and it is estimated that it could fetch a price of $ 600,000.
