In 1977, NASA sent out two Voyager spacecrafts carrying tons of pictures aliens might see someday. Known as the Voyager Golden Records, these photos and recordings of life on Earth were meant as a chronicle of our planet that would travel beyond our solar system and into interstellar space. This means that records of our existence may very well outlast our own sun, as they travel to another solar system. Will another civilization one day find our story on these golden records?
Famous astronomer Carl Sagan chose the images that were to be included in the records.
"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," Sagan said of the Voyager project in a press release from 1977.
Of the two Voyager spacecrafts, Voyager I, has traveled the farthest so far, crossing the heliosphere - a bubble created around our solar system by the Sun's solar wind - and has entered the interstellar medium - the space that exists between star systems. It is the first spacecraft to travel this far. It's expected that the craft will no longer be able to power itself by 2025 and die in space. Before it does, hopefully the surreal and bizarre images selected to be on the Golden Discs will reach extra terrestrial intelligence.
