Great Moon Hoax of 1835
The New York Sun published articles claiming astronomer John Herschel had discovered life on the Moon, including bat-winged humanoids and unicorns. It became the first major media hoax about extraterrestrial life.
In the late summer of 1835, the readers of the New York Sun were treated to one of the most extraordinary series of newspaper articles ever published. Over the course of six installments beginning on August 25, the paper reported that the eminent British astronomer Sir John Herschel, working from a new observatory at the Cape of Good Hope in South Africa, had turned a revolutionary telescope of unprecedented power upon the surface of the Moon and discovered there a world teeming with life. Vast forests covered the lunar landscape. Herds of miniature bison grazed on open plains. Blue unicorns with single horns drank from crystal-clear rivers. And most astounding of all, bat-winged humanoid creatures walked upright, built temples of polished sapphire, and appeared to possess language and civilization. The articles caused an international sensation, boosted the Sun’s circulation to the highest of any newspaper in the world, and fooled scientists, clergymen, and ordinary readers alike before being exposed as an elaborate fabrication. The Great Moon Hoax, as it came to be known, stands as the first major media deception about extraterrestrial life, a landmark in the history of journalism, and a cautionary tale about the human eagerness to believe in life beyond our world that remains as relevant today as it was nearly two centuries ago.
The World of 1835
To understand why the Moon Hoax succeeded so spectacularly, one must appreciate the world in which it appeared. The 1830s were an era of extraordinary scientific discovery and public fascination with the natural world. Charles Darwin was in the midst of his voyage on HMS Beagle, sending back reports of exotic creatures from the far corners of the globe. New species of animals and plants were being catalogued at a rate that seemed to promise infinite biological variety. The boundaries of the known world were expanding rapidly, and the public appetite for marvels was virtually insatiable.
Astronomy was the most glamorous of the sciences, and the astronomer was a figure of almost mythic stature in the popular imagination. The Herschel family occupied the pinnacle of astronomical fame. Sir William Herschel, John’s father, had discovered the planet Uranus in 1781 and had spent decades cataloguing nebulae and double stars. John Herschel had continued his father’s work and was, in 1835, genuinely stationed at the Cape of Good Hope, conducting an astronomical survey of the southern sky. His name carried an authority in scientific matters that was virtually unchallengeable by the general public.
The technology of communication was slow enough to make verification of distant claims extremely difficult. News from South Africa took weeks or months to reach New York by ship. There was no telegraph, no cable, no means of rapidly checking the claims made in the Sun’s articles against the actual activities of John Herschel at the Cape. By the time any rebuttal could arrive from South Africa, the hoax would have run its course and achieved its purposes.
The newspaper industry itself was in a state of revolution. The penny press, of which the New York Sun was a pioneer, was transforming journalism from a sedate enterprise aimed at educated elites into a raucous, competitive business that depended on mass circulation and sensational content. Founded by Benjamin Day in 1833, the Sun sold for one cent, a fraction of the price charged by established papers, and its business model depended on attracting the largest possible readership with stories that were exciting, accessible, and, when necessary, somewhat elastic in their relationship to the truth.
Richard Adams Locke
The author of the Moon Hoax articles was Richard Adams Locke, a Cambridge-educated English journalist who had emigrated to New York and joined the staff of the Sun in 1835. Locke was a talented writer with a sophisticated understanding of both science and the popular imagination. He was also frustrated by what he saw as the uncritical credulity of the public and the willingness of certain scientists and clergymen to make sweeping claims about life on other worlds without evidence to support them.
In particular, Locke was irritated by the writings of Thomas Dick, a Scottish church minister and amateur astronomer who had published popular books claiming that the Moon was inhabited and that the other planets of the solar system teemed with intelligent life. Dick calculated the population of the Moon at 4.2 billion and claimed that even the rings of Saturn were inhabited. His books sold well and were taken seriously by a significant portion of the reading public, a circumstance that Locke found both absurd and dangerous.
Locke’s original intention, or so he later claimed, was satirical. By presenting obviously fantastical claims about lunar life in the guise of legitimate scientific reporting, he hoped to demonstrate the absurdity of Dick’s assertions and the gullibility of those who accepted them. If people would believe in bat-winged humanoids and blue unicorns on the Moon simply because the claims were attributed to a famous astronomer, what did that say about their critical faculties? The hoax was meant to be a mirror held up to public credulity, though Locke may have underestimated how thoroughly that mirror would reflect his own capacity for deception.
The Articles
The first article appeared in the New York Sun on Tuesday, August 25, 1835, under the headline “Great Astronomical Discoveries Lately Made by Sir John Herschel, LL.D., F.R.S., etc., at the Cape of Good Hope.” The piece was attributed to “Dr. Andrew Grant,” described as a colleague of Herschel’s, and was presented as a reprint from the Edinburgh Journal of Science, a real publication that had, however, ceased to exist several years earlier, a detail that apparently escaped notice.
The opening installment was carefully designed to establish credibility. It described Herschel’s telescope in elaborate technical detail, employing enough genuine optical terminology to sound authoritative to non-experts while making claims that any actual astronomer would have recognized as impossible. The telescope was said to have an objective lens of unprecedented size and to employ a new “hydro-oxygen” illumination technique that allowed magnification of such power that objects on the lunar surface could be observed at a resolution equivalent to viewing them from a distance of about eighty yards.
The second and third articles began to describe the wonders that this miraculous instrument had revealed. The lunar surface, far from being the barren wasteland that ordinary telescopes showed, was covered with lush vegetation. Forests of dark red trees, fields of bright flowers, and expanses of green grass were described in vivid detail. Bodies of water were present, including a vast inland sea. The geological features were equally dramatic, with crystal-line formations, beaches of brilliant white sand, and mountains of amethyst.
Animals began to appear in the fourth article. Small creatures resembling bison were observed grazing in herds. A blue, single-horned animal resembling a goat, the “monoceros” or unicorn, was described moving gracefully through meadows. Bipedal beavers without tails walked upright, carried their young in their arms, and appeared to live in huts, suggesting a rudimentary intelligence. Birds of extraordinary plumage filled the trees, and creatures unlike anything on Earth were catalogued with the confident precision of a naturalist describing specimens.
The climax came in the fifth article, which introduced the Vespertilio-homo, the bat-men of the Moon. These creatures were described as approximately four feet tall, with yellowish-brown fur, wings composed of a thin membrane like those of a bat, and faces that bore an undeniable resemblance to human beings. They walked upright, gestured to one another in what appeared to be conversation, and seemed to possess emotions including curiosity and affection. They were observed bathing in streams, eating fruit from the abundant lunar orchards, and constructing or inhabiting structures that included an enormous temple built from polished sapphire, featuring a roof supported by pillars and what appeared to be an altar.
The sixth and final article brought the series to an abrupt end by claiming that the telescope had been accidentally left pointing at the Sun, which had concentrated the solar rays through the lens and set fire to the observatory. The damage, the article claimed, would take weeks to repair, conveniently closing off any possibility of further observations or verification.
The Reaction
The public response to the Moon Hoax articles was nothing short of extraordinary. The Sun’s circulation, already the largest in New York, soared to approximately nineteen thousand copies daily, making it the best-selling newspaper in the world at the time. Copies were reprinted in newspapers throughout the United States and Europe. Pamphlet editions were published and sold briskly. The story was discussed in churches, lecture halls, taverns, and drawing rooms across the English-speaking world.
The degree of credulity displayed by the public was remarkable. Many readers accepted the articles entirely at face value, despite their increasingly fantastical content. The scientific trappings, the invocation of Herschel’s authority, and the confident, detailed tone of the writing proved sufficient to overwhelm the skepticism that bat-winged humanoids and sapphire temples on the Moon might otherwise have inspired. Some readers questioned specific details while accepting the general premise that life had been discovered on the Moon. Others were simply carried away by the excitement of the story, preferring the thrill of belief to the tedium of doubt.
Even some scientists were initially taken in. A delegation from Yale University reportedly traveled to New York to examine the original Edinburgh Journal of Science article, only to be sent from office to office at the Sun in a runaround that prevented them from inspecting a document that did not exist. Other scientists recognized the hoax immediately but were unsure whether to denounce it publicly, reluctant to seem like killjoys in the face of such popular enthusiasm.
The religious community’s response was particularly noteworthy. Some clergymen embraced the discoveries as evidence of God’s creative abundance, arguing that the existence of life on the Moon confirmed the biblical account of creation and suggested that the Almighty had populated the entire cosmos with living creatures. Others were disturbed by the theological implications of intelligent life on other worlds, a possibility that raised uncomfortable questions about the universality of salvation and the status of non-human rational beings in God’s plan.
The Unraveling
The hoax began to unravel within weeks of its publication, though it was never formally retracted by the Sun. Rival newspapers, particularly James Gordon Bennett’s New York Herald, raised skeptical questions about the articles and challenged the Sun to produce the original Edinburgh Journal of Science from which the articles were supposedly reprinted. The Journal of Commerce, another New York paper, admitted that it had been preparing to reprint the articles when members of its staff discovered that the Edinburgh Journal of Science had ceased publication years earlier.
Richard Adams Locke was identified as the probable author, though he never formally admitted his authorship during his lifetime. When confronted, he gave evasive answers that neither confirmed nor denied his role. The Sun itself treated the matter with studied ambiguity, never publishing a retraction or correction but allowing the story to fade from prominence as public attention moved on to other matters.
Sir John Herschel, meanwhile, was working peacefully at the Cape of Good Hope, entirely unaware of the sensation being created in his name. When news of the articles finally reached him, he was reportedly amused, remarking that his actual observations could not possibly compete with the invented ones for public interest. As time wore on, however, Herschel grew increasingly annoyed by the association of his name with the hoax, particularly as credulous correspondents continued to write to him seeking confirmation of the lunar discoveries for years afterward.
The Deeper Significance
The Great Moon Hoax of 1835 was more than a journalistic prank. It was a revelation about the nature of belief, the power of authority, and the human desire to find life beyond Earth. These themes, first illuminated by Locke’s fabrication, have recurred throughout the subsequent history of extraterrestrial claims, from the Martian canal craze of the late nineteenth century to the flying saucer era of the twentieth to the UAP investigations of the twenty-first.
The hoax demonstrated the extraordinary power of institutional authority to shape belief. The articles were believed primarily because they were attributed to John Herschel, a scientist whose reputation was beyond question. The public did not evaluate the claims on their merits, which were absurd, but on the authority of the person to whom they were attributed. This pattern of authority-dependent belief has repeated itself countless times since, from Orson Welles’s War of the Worlds broadcast in 1938 to the uncritical acceptance of expert opinion in the modern media landscape.
The hoax also revealed the depth of the human desire to believe that we are not alone in the universe. The eagerness with which the public embraced the lunar discoveries, the reluctance with which it abandoned them, and the wistfulness that accompanied their debunking all spoke to a longing that transcended rational inquiry. People wanted the Moon to be inhabited. They wanted the cosmos to be full of life and wonder. They wanted the universe to be the kind of place where bat-winged humanoids built sapphire temples in lunar meadows. The fact that it was not, that the Moon was a dead, airless world of dust and rock, was a disappointment that the public accepted only with reluctance and regret.
The media’s role as gatekeeper of public knowledge was thrown into sharp relief. The penny press had created a new relationship between journalism and its audience, one based on volume and sensation rather than accuracy and restraint. The Sun’s editors understood that a story about life on the Moon would sell papers, and they were not overly concerned about whether it was true. This dynamic, the prioritization of engagement over accuracy, would become a defining challenge of journalism in the centuries that followed, reaching its apotheosis in the age of social media and algorithmic content distribution.
Legacy of Credulity
The Great Moon Hoax cast a long shadow over the subsequent history of extraterrestrial claims. It established a template, sensational announcement, initial excitement, gradual skepticism, eventual debunking, that would repeat itself with variations throughout the following two centuries. When Percival Lowell claimed to see canals on Mars in the 1890s, when tabloids trumpeted the discovery of alien artifacts on the Moon in the 1960s, when the meteorite ALH84001 was announced as containing possible Martian fossils in 1996, the pattern first established by the Moon Hoax was visibly at work: the invocation of scientific authority, the eager public acceptance, the media amplification, and the eventual, reluctant return to uncertainty.
The hoax also contributed to a lasting skepticism about astronomical claims, particularly those involving extraterrestrial life. Having been burned once by the Moon Hoax, the scientific establishment became notably more cautious about announcing discoveries that might be perceived as evidence of life beyond Earth. This caution has both positive and negative effects: it protects the public from false claims, but it also creates a culture of conservatism that may delay the recognition of genuine discoveries.
Richard Adams Locke died in 1871, largely forgotten despite having perpetrated one of the most successful hoaxes in the history of journalism. His Moon articles, intended as satire, had worked too well, fooling the very people he had meant to educate and demonstrating that the line between enlightenment and deception is far thinner than the rationalist might wish to believe. The Sun continued publishing until 1950, having long since abandoned the sensationalist tactics of its early years but never quite living down its role in the great lunar swindle of 1835.
The Moon itself remains lifeless, as far as we know. No bat-winged humanoids build sapphire temples in lunar craters. No blue unicorns graze on the Sea of Tranquility. The magnificent landscape that Richard Adams Locke imagined remains exactly what it has always been: a beautiful fiction, a testament to the power of the human imagination and the enduring hope that somewhere, somehow, we are not alone.
