One of the most amazing things that caught my attention in the Voyager mission is the Golden Record. It is a special disc on board the Voyager spacecraft (Voyager 1 and Voyager 2), launched in 1977 to explore the outer planets and are now in interstellar space. It is part of the Voyager project that was overseen by astronomer Carl Sagan and his team to create a record of our planet as a "time capsule" for intelligent life that may encounter it in the distant future.
The record aims to provide an accurate picture of life on Earth in simple and universal terms. The disc contains approximately 90 minutes of audio, including music from various times and cultures, including classical works by Bach, Beethoven, and Mozart, as well as more contemporary songs such as Chuck Berry's "Johnny B. Goode" and traditional music from Africa, Asia, Europe, and North America.
Furthermore, it provides a sound image of Earth by also containing natural sounds such as wind, rain, thunder, ocean waves, bird songs, whale songs, footsteps, and human laughter.
The Golden Record also has spoken greetings in 55 different languages, with each saying hello or peace from Earth to show the different languages and cultures of our planet. Additionally, the record contains 115 images (of humans, animals, science, and the planet), which are encoded in such a way that they can be reconstructed using the instructions contained on the record.

Included in this record were distinct symbols used to convey information, including guidance through diagrams (not photos) regarding the proper use of the recorded media.
One diagram illustrates the outline of a hydrogen atom, which provides a base reference point for both time and measures, as hydrogen is consistent throughout space-time.
Another diagram depicts the process of playing the record image, including the appropriate revolution speed of 16⅔ revolutions per minute, the position of the needle, and how to read the signal produced by the record.
There is a pulsar map on the record showing 14 pulsars, whose precise periods are given. This map makes it possible to determine the location of our solar system in the Milky Way galaxy. The unique signals from pulsars create a kind of cosmic address that points to the solar system. The additional diagrams on the record also include step-by-step instructions to convert the information contained on the record into visual imagery by decoding the information to recreate all 115 photographic images.
This collective set of drawings offers a universal operating manual for the record. They provide explicit instructions for how to play the record and also show where the record was made and how to understand the contents without any need for a human language basis.
What incredible and original thoughts by our scientists and thinkers! The Golden Record is more than a scientific achievement; it is a message in a bottle that represents humanity at its best. It reminds us that even in the vastness of space, humanity strives to connect and reach out, impelled by curiosity, creativity and hope, ever reaching out to understand the universe while leaving behind a small part of who we are.
