Do you know how aliens would hear us? No coded language! They will be listening to the sounds and words humans hear on a daily basis. NASA has uploaded on SoundCloud the recordings of various sounds on Earth that were carried on the two Voyager spacecraft, launched in 1977, to greet any extraterrestrials that the probes may encounter, reports Indian Express.
Spoken greetings from Earth people in 55 languages, including Indian languages like Hindi, Marathi, Bengali, were included among others.
The other sounds selected to represent all of humanity were recordings of rain, a mother and child, stone tools and a heartbeat and musical selections from different cultures and eras.
Voyager 2, launched on August 20, 1977, and Voyager 1, launched about two weeks later on September 5, both carried the Golden Records encoded with the sounds of Earth. The contents of the same were selected by the late astronomer Carl Sagan of Cornell University.
Carl Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals.
