What Is the Voyager Golden Record?

The Voyager Golden Record is a phonograph record sent into space aboard NASA's Voyager 1 and Voyager 2 spacecraft, launched in 1977. These spacecraft were designed to explore the outer planets of our solar system, and scientists wanted them to carry a message from Earth in case they were ever discovered by extraterrestrial life. The record itself is made of copper and plated with gold, which protects it from damage in the harsh environment of space.

The idea behind the Golden Record came from Carl Sagan, the famous astronomer and science communicator, and his team at Cornell University. They believed that if these spacecraft ever encountered intelligent beings from other civilizations, the record would serve as a time capsule representing life on Earth. The record contains sounds, images, and music selected to represent human culture, nature, and scientific knowledge.

The physical record measures 12 inches in diameter and plays at 16⅔ rotations per minute. Voyager 1, launched on September 5, 1977, carries one copy of the Golden Record. Voyager 2, launched on August 20, 1977, carries another identical copy. As of 2024, Voyager 1 has traveled more than 15 billion miles from Earth and continues to move deeper into interstellar space. Voyager 2 has traveled more than 12 billion miles. At their current speeds, these spacecraft will not come close to another star system for approximately 40,000 years.

Practical takeaway: Understanding the Golden Record's purpose helps you appreciate how scientists think about representing humanity to the universe and what they chose as important aspects of our world.

The Sounds and Greetings Included

One of the most compelling parts of the Voyager Golden Record consists of greetings spoken in 55 languages from around the world. These greetings were recorded by speakers from different countries and cultures. The greetings range from simple phrases like "Hello" to longer welcome statements. For example, the Akkadian greeting, one of the oldest recorded languages, translates to "May all be well." The Chinese greeting says, "Friends of space, how are you all?" These greetings represent humanity's attempt to reach out peacefully across the cosmos.

Beyond the spoken greetings, the record contains natural sounds from Earth. These sounds paint an acoustic picture of our planet and include things like wind, rain, thunder, ocean waves, and various animal calls. Listeners can hear the sounds of humpback whales, a chimpanzee, and birds. The record also features urban sounds such as a car horn and footsteps on pavement, representing human activity and our built environment. These audio recordings were carefully selected to give any potential listeners a sense of the soundscape that creatures on Earth experience.

Scientific sounds are also included on the record. These include the sound of a human heartbeat and human laughter, which were chosen to represent the biological nature of human life. Brain activity waves were translated into sound, offering an abstract representation of human thought. The pulsar signal, a regular radio signal from a pulsar star, was included as a way to help any advanced civilization date the record, since pulsars slow down over time in a measurable way.

The record opens with this message from UN Secretary-General Kurt Waldheim: "I send greetings on behalf of the Secretary-General of the United Nations, the representatives of the world community. As we cast our lot with the future, we hope for the health and the happiness of all humankind. I hope that someday, when the Voyagers have completed their mission, they may become a symbol of our hopes and our determinations and our good intentions in this universe of ours." This greeting emphasizes themes of unity and peaceful intentions.

Practical takeaway: The combination of spoken greetings, natural sounds, and human biological sounds shows how scientists attempted to represent not just what humans say, but how we sound and the world we inhabit.

The Musical Selections

Music was considered one of the most universal aspects of human culture, so the Golden Record includes 27 musical pieces from various cultures around the world. These selections span classical, folk, and popular traditions. The music was chosen to represent the diversity of human musical expression and was recorded using the best technology available in the 1970s. The Carl Sagan Committee, which oversaw the project, believed that music could communicate human emotion and creativity in ways that transcended language.

The musical selections include classical works by composers such as Ludwig van Beethoven, Johann Sebastian Bach, and Wolfgang Amadeus Mozart. Beethoven's "Symphony No. 5" appears on the record, representing Western classical tradition. Bach's "The Art of Fugue" demonstrates complex mathematical and structural elements in music. These selections showcase the sophisticated musical achievements of European composers.

The record also includes music from non-Western traditions. "Prikhodis na Sich Krayinas," a Ukrainian folk song performed by Marta Kobalia, represents Eastern European culture. "Ugandan Pearl," an African piece, brings music from the African continent. Japanese court music, specifically "Kinds of Flowers" from the Gagaku tradition, represents Asian musical heritage. These selections demonstrate that music is valued across all human cultures and that different societies have developed complex musical systems independent of one another.

Additional musical selections include pieces that represent different human emotions and experiences. Louis Armstrong's "Melancholy Blues" represents American jazz, a uniquely American art form that emerged from African American cultural traditions. This choice acknowledges both the artistic importance of jazz and its role in American culture. Traditional music from India, Peru, and other regions round out the collection, showing the global scope of the selections.

The complete musical track list includes works from cultures spanning six continents. No single musical tradition dominates the selection, reflecting an intentional effort to represent humanity as a diverse, multicultural species. The music ranges from pieces thousands of years old to contemporary works from the 1970s, showing human musical development across time.

Practical takeaway: The musical selections show how music represents human emotions, cultural identity, and artistic achievement, and these qualities were considered important enough to share with potential extraterrestrial life.

The Scientific and Mathematical Images

The Voyager Golden Record contains 115 images encoded on the record in a special format that can be read and converted into photographs by the appropriate equipment. These images were actually the first pictures of Earth ever sent beyond our solar system. The images include scientific diagrams, mathematical concepts, and photographs of Earth and human life. They were encoded in analog form, a technology that could be read even by civilizations using different technological approaches than ours.

The scientific images begin with basic information about the universe and physics. The record includes a pulsar map showing the location of Earth relative to 14 pulsars, allowing any advanced civilization to potentially locate our solar system. It includes images depicting the structure of atoms and molecules, showing basic chemistry. The record contains mathematical diagrams demonstrating concepts like the Pythagorean theorem and pi, allowing mathematical communication even if the civilizations don't speak the same language.

The biological images include diagrams of the DNA double helix, representing the molecular basis of life on Earth. The record shows the structure of human anatomy, including images of the human body in different poses. There are images depicting human reproduction and development, from conception to birth to aging. These images communicate information about human biology and the human life cycle. The record also includes images of the human brain, representing our capacity for thought and consciousness.

Photographs of Earth include images of cities, farmland, and natural landscapes. These photographs show the diversity of Earth's environments and human civilization. Images show the Great Wall of China, various cities around the world, and people engaged in different activities. There are images of cultural artifacts, including art and architecture from different civilizations. The photographs together create a visual portrait of Earth as a living, populated planet with diverse cultures and landscapes.

Practical takeaway: The images on the Golden Record demonstrate how visual information can communicate scientific concepts and information about Earth, allowing for a form of communication that doesn't depend on shared language or alphabets.

How the Record Is Designed to Be Played

The Voyager Golden Record is not a standard phonograph record and cannot be played on an ordinary home stereo system. Instead, it requires specialized equipment to decode and play. The record comes with a stylus cartridge and instructions, also included on the record itself, for how to build the equipment needed to play it.
