Upon watching one of the most incredible new shows "Cosmos" on my hulu account, a very little fact shared struck me during the episode about the Milky Way. The Voyager 1 still orbiting in space has records on board called The Golden Records. Simply amazing. And the best part is I just got new noise canceling headphones.. what better way to celebrate that then to listen to The Sounds of Earth that were meant to be heard by alien civilizations?
The Voyager Golden Records are gramophone records which were included aboard both Voyager spacecrafts, 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 intelligentextraterrestrial life form, or for future humans, who may find them. The Voyager spacecrafts are not heading towards any particular star, butVoyager 1 will be within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 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 civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet." Thus the record is best seen as a time capsule or a symbolic statement more than a serious attempt to communicate with extraterrestrial life.
Of course I'm going to give you the link to listen to the record! You're welcome! The second link is also a link to a page of
actual "earth sounds" that are on board including "wild dogs", "mud pots", and a "tame dog" just to name a few. The third link is
for a run down of the actual songs featured on the Voyager 1 and 2.
