“The Voyager Golden Record is a phonograph record included in the two Voyager spacecraft launched in 1977. It contains sounds and images selected to portray the diversity of life and culture on Earth. It is intended for any intelligent extraterrestrial life form, or far future humans, that may find it. The Voyager spacecraft are not heading towards any particular star, its pretty much just going as far as it can go in a straight direction.
As the probes are extremely small compared to the vastness of interstellar space, it is extraordinarily unlikely that they will ever be accidentally encountered. If they are ever found by an alien species, it will most likely be far in the future, and thus the record is best seen as a time capsule or a symbolic statement rather than a serious attempt to communicate with extraterrestrial life.” from http://hypebeast.com/blog/kinfolk/2010/08/voyager-golden-record/
