THE SOUNDS OF THE EARTH

The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extreterrestial life form, or for future humans, who may find them. The Voyager spacecraft are not heading toward any particular star, but voyager  will be within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardali, in about 40000 years.

As the probes are extremely small compared to the vastness of interstellar space, the probability of a space-faring civilization encountering them is very small, especially since the probes will eventually stop emitting electromagnetic radiation meant for communication.

Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilization in interstellar space. But the launching of this " bottle into the cosmic oc  says something very hopeful about life on this planet." Thus the record is best seen as a time capsule.
