What Is on Voyager’s Golden Record?

From a whale song to a kiss, the time capsule sent into space in 1977 had some interesting contents

“I thought it was a brilliant idea from the beginning,” says Timothy Ferris. Produce a phonograph record containing the sounds and images of humankind and fling it out into the solar system.

By the 1970s, astronomers Carl Sagan and Frank Drake already had some experience with sending messages out into space. They had created two gold-anodized aluminum plaques that were affixed to the Pioneer 10 and Pioneer 11 spacecraft. Linda Salzman Sagan, an artist and Carl’s wife, etched an illustration onto them of a nude man and woman with an indication of the time and location of our civilization.

The “Golden Record” would be an upgrade to Pioneer’s plaques. Mounted on Voyager 1 and Voyager 2, twin probes launched in 1977, the two copies of the record would serve as time capsules and transmit much more information about life on Earth should extraterrestrials find it.

NASA approved the idea. So then it became a question of what should be on the record. What are humanity’s greatest hits? Curating the record’s contents was a gargantuan task, and one that fell to a team including the Sagans, Drake, author Ann Druyan, artist Jon Lomberg and Ferris, an esteemed science writer who was a friend of Sagan’s and a contributing editor to Rolling Stone.

The exercise, says Ferris, involved a considerable number of presuppositions about what aliens want to know about us and how they might interpret our selections. “I found myself increasingly playing the role of extraterrestrial,” recounts Lomberg in Murmurs of Earth, a 1978 book on the making of the record. When considering photographs to include, the panel was careful to try to eliminate those that could be misconstrued. Though war is a reality of human existence, images of it might send an aggressive message when the record was intended as a friendly gesture. The team veered from politics and religion in its efforts to be as inclusive as possible given a limited amount of space.

Over the course of ten months, a solid outline emerged. The Golden Record consists of 115 analog-encoded photographs, greetings in 55 languages, a 12-minute montage of sounds on Earth and 90 minutes of music. As producer of the record, Ferris was involved in each of its sections in some way. But his largest role was in selecting the musical tracks. “There are a thousand worthy pieces of music in the world for every one that is on the record,” says Ferris. I imagine the same could be said for the photographs and snippets of sounds.

The following is a selection of items on the record:

Silhouette of a Male and a Pregnant Female

The team felt it was important to convey information about human anatomy and culled diagrams from the 1978 edition of The World Book Encyclopedia. To explain reproduction, NASA approved a drawing of the human sex organs and images chronicling conception to birth. Photographer Wayne F. Miller’s famous photograph of his son’s birth, featured in Edward Steichen’s 1955 “Family of Man” exhibition, was used to depict childbirth. But as Lomberg notes in Murmurs of Earth, NASA vetoed a nude photograph of “a man and a pregnant woman quite unerotically holding hands.” The Golden Record experts and NASA struck a compromise that was less compromising—silhouettes of the two figures and the fetus positioned within the woman’s womb.

DNA Structure

At the risk of providing extraterrestrials, whose genetic material might well also be stored in DNA, with information they already knew, the experts mapped out DNA’s complex structure in a series of illustrations.

Demonstration of Eating, Licking and Drinking

When producers had trouble locating a specific image in picture libraries maintained by the National Geographic Society, the United Nations, NASA and Sports Illustrated, they composed their own. To show a mouth’s functions, for instance, they staged an odd but informative photograph of a woman licking an ice-cream cone, a man taking a bite out of a sandwich and a man drinking water cascading from a jug.

Olympic Sprinters

Images were selected for the record based not on aesthetics but on the amount of information they conveyed and the clarity with which they did so. It might seem strange, given the constraints on space, that a photograph of Olympic sprinters racing on a track made the cut. But the photograph shows various races of humans, the musculature of the human leg and a form of both competition and entertainment.

Taj Mahal

Photographs of huts, houses and cityscapes give an overview of the types of buildings seen on Earth. The Taj Mahal was chosen as an example of the more impressive architecture. The majestic mausoleum prevailed over cathedrals, Mayan pyramids and other structures in part because Mughal Emperor Shah Jahan built it in honor of his late wife, Mumtaz Mahal, and not a god.

Golden Gate Bridge

Three-quarters of the record was devoted to music, so visual art was less of a priority. A couple of photographs by the legendary landscape photographer Ansel Adams were selected, however, for the details captured within their frames. One, of the Golden Gate Bridge from nearby Baker Beach, was thought to clearly show how a suspension bridge connected two pieces of land separated by water. The hum of an automobile was included in the record’s sound montage, but the producers were not able to overlay the sounds and images.

A Page from a Book

An excerpt from a book would give extraterrestrials a glimpse of our written language, but deciding on a book and then a single page within that book was a massive task. For inspiration, Lomberg perused rare books, including a first-folio Shakespeare, an elaborate edition of Chaucer from the Renaissance and a centuries-old copy of Euclid’s Elements (on geometry), at the Cornell University Library. Ultimately, he took MIT astrophysicist Philip Morrison’s suggestion: a page from Sir Isaac Newton’s System of the World, where the means of launching an object into orbit is described for the very first time.

Greeting from Nick Sagan

To keep with the spirit of the project, says Ferris, the wordings of the 55 greetings were left up to the speakers of the languages. In Burmese, the message was a simple, “Are you well?” In Indonesian, it was, “Good night ladies and gentlemen. Goodbye and see you next time.” A woman speaking the Chinese dialect of Amoy uttered a welcoming, “Friends of space, how are you all? Have you eaten yet? Come visit us if you have time.” It is interesting to note that the final greeting, in English, came from then-6-year-old Nick Sagan, son of Carl and Linda Salzman Sagan. He said, “Hello from the children of planet Earth.”

Whale Greeting

Biologist Roger Payne provided a whale song (“the most beautiful whale greeting,” he said, and “the one that should last forever”) captured with hydrophones off the coast of Bermuda in 1970. Thinking that perhaps the whale song might make more sense to aliens than to humans, Ferris wanted to include more than a slice and so mixed some of the song behind the greetings in different languages. “That strikes some people as hilarious, but from a bandwidth standpoint, it worked quite well,” says Ferris. “It doesn’t interfere with the greetings, and if you are interested in the whale song, you can extract it.”

A Kiss

Reportedly, the trickiest sound to record was a kiss. Some were too quiet, others too loud, and at least one was too disingenuous for the team’s liking. Music producer Jimmy Iovine kissed his arm. In the end, the kiss that landed on the record was actually one that Ferris planted on Ann Druyan’s cheek.

Life Signs

Druyan had the idea to record a person’s brain waves, so that should extraterrestrials millions of years into the future have the technology, they could decode the individual’s thoughts. She was the guinea pig. In an hour-long session hooked to an EEG at New York University Medical Center, Druyan meditated on a series of prepared thoughts. In Murmurs of Earth, she admits that “a couple of irrepressible facts of my own life” slipped in. She and Carl Sagan had gotten engaged just days before, so a love story may very well be documented in her neurological signs. Compressed into a minute-long segment, the brain waves sound, writes Druyan, like a “string of exploding firecrackers.”

Georgian Chorus—“Tchakrulo”

The team discovered a beautiful recording of “Tchakrulo” by Radio Moscow and wanted to include it, particularly since Georgians are often credited with introducing polyphony, or music with two or more independent melodies, to the Western world. But before the team members signed off on the tune, they had the lyrics translated. “It was an old song, and for all we knew could have celebrated bear-baiting,” wrote Ferris in Murmurs of Earth. Sandro Baratheli, a Georgian speaker from Queens, came to the rescue. The word “tchakrulo” can mean either “bound up” or “hard” and “tough,” and the song’s narrative is about a peasant protest against a landowner.

Chuck Berry’s “Johnny B. Goode”

According to Ferris, Carl Sagan had to warm up to the idea of including Chuck Berry’s 1958 hit “Johnny B. Goode” on the record, but once he did, he defended it against others’ objections. Folklorist Alan Lomax was against it, arguing that rock music was adolescent. “And Carl’s brilliant response was, ‘There are a lot of adolescents on the planet,’” recalls Ferris.

On April 22, 1978, Saturday Night Live spoofed the Golden Record in a skit called “Next Week in Review.” Host Steve Martin played a psychic named Cocuwa, who predicted that Time magazine would reveal, on the following week’s cover, a four-word message from aliens. He held up a mock cover, which read, “Send More Chuck Berry.”

More than four decades later, Ferris has no regrets about what the team did or did not include on the record. “It means a lot to have had your hand in something that is going to last a billion years,” he says. “I recommend it to everybody. It is a healthy way of looking at the world.”

According to the writer, NASA approached him about producing another record but he declined. “I think we did a good job once, and it is better to let someone else take a shot,” he says.

So, what would you put on a record if one were being sent into space today?
