The Golden Record of Voyager 1

In 1977, NASA launched one of the most ambitious space missions ever—certainly the longest, since it's still going on. Voyager 1 and 2 were destined to go farther than any other human-made object, and in 2012, Voyager 1 became the first of its kind to reach interstellar space. It must be awfully lonely out there... but just in case it's not, the little craft is equipped with a message of peace from Earth to who or what ever might find it. The "Golden Record" starts slow with the universal language of math, then gradually works up to demonstrate human-centric concepts such as music, art, and spoken greetings in 55 different languages. The record was the brainchild of Carl Sagan, who had this to say about the likelihood of its finding life out there: "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet." Oh Carl. Even beyond the heliosphere, you are such a ray of sunshine.
