How a 19th century newspaper convinced readers the moon was full of bat-people

In the late summer of 1835, thousands of readers in New York opened their paper and learned that the moon was inhabited by horned, furry bat-people who built temples, kept herds of bison and lived in shining cities of crystal.

For several breathless days, many people believed it. The story was a complete fabrication, but it reveals a lot about science, media and why humans are so quick to trust a good story.

What exactly was the Great Moon Hoax?

In August 1835, the New York Sun, a relatively new and inexpensive daily paper, began running a series of articles supposedly reprinted from a Scottish scientific journal. They claimed that the famous British astronomer Sir John Herschel had made astonishing discoveries while observing the moon from South Africa.

The articles described forests, oceans, sapphire pyramids, unicorn-like goats, tailless beavers that walked upright and, most famously, winged “man-bats” with human faces and webs of skin between their arms and legs. Each installment added new wonders, encouraging readers to buy the next paper.

Why did so many people believe it?

From a modern perspective, the idea of bat-people on the moon sounds obviously ridiculous. In 1835 it did not seem quite so absurd to many readers. Telescopes were rapidly improving, and scientific discoveries were transforming how people saw the universe.

Crucially, the article linked itself to a real person: John Herschel was genuinely one of the most respected astronomers of his time and had indeed traveled to the Cape of Good Hope to study the southern sky. That touch of truth made the invented details seem more plausible.

The media environment of the 1830s

The New York Sun was part of a new wave of “penny papers” that sold for a very low price and relied on huge circulation numbers rather than expensive subscriptions. To survive, they needed attention: gripping stories, scandals and oddities that readers would talk about and share.

At the time, there were fewer established norms about fact-checking or scientific reporting. Publishers competed to be lively and entertaining. The moon articles fit perfectly: they combined science, adventure and spectacle, wrapped in a confident, matter-of-fact tone.

How the hoax actually worked

The series used several tricks that still appear in misleading stories today:

• Borrowed authority:It invoked real scientists, observatories and instruments, anchoring fantasy in genuine names and places.
• Technical details:The articles included discussions of lenses and magnification, which sounded convincingly scientific even to non-specialists.
• Serial structure:The discoveries unfolded over multiple days, giving the illusion of an ongoing investigation and allowing excitement to build gradually.
• Visual imagination:Readers were encouraged to picture landscapes, buildings and creatures, which made the story feel concrete.

Illustrations later circulated that showed the bat-people and lunar scenes, further blurring the line between report and fantasy, even though they were produced after the original text.

Did everyone fall for it?

Not quite. Contemporary accounts suggest that some readers immediately suspected a joke or satire. A few rival newspapers raised doubts, and some scientifically trained readers understood that the details did not match what telescopes could actually reveal.

However, the hoax spread widely, and for a time many people either believed it outright or treated it as possibly true. The Sun did not rush to correct the story. Eventually, as skepticism grew, the paper allowed the hoax interpretation to stand without a dramatic confession.

What it reveals about its time

The moon story sits at a crossroads of several 19th century trends. It shows how fascinated people were with astronomy and how eager they were to imagine other worlds populated by intelligent beings.

It also reflects changing attitudes toward newspapers. The penny press made news a mass product rather than a luxury for elites. That democratization was powerful but also created incentives to prioritize attention over accuracy.

Why the moon hoax still matters today

Many of the mechanisms that made the bat-people story work are still with us, just delivered through different technologies. Modern readers encounter attention-grabbing headlines about health, technology or distant planets that sometimes stretch or distort underlying facts.

The moon hoax offers a few practical habits that still help:

• Check the source:Does the piece rely on a single newspaper or website, or can you find confirmation from independent outlets or official institutions?
• Look for names:If a scientist or organization is mentioned, see if they really exist and whether they have acknowledged the claim.
• Beware of perfect stories:If a story fits too neatly into a thrilling narrative or seems designed mainly to amaze, pause and look more closely.
• Notice the tone:Confident, detailed language can sound authoritative even when it is not. Ask whether there are uncertainties or limitations explained.

A curious legacy

In later years the Great Moon Hoax became a favorite example for historians of journalism and science communication. It is often retold not simply as a prank, but as a case study in how storytelling power can overwhelm skepticism.

There are no bat-people on the moon, but the episode reminds us that humans are often happier to inhabit a vivid story than a dull reality. Learning to enjoy remarkable claims without immediately trusting them is a skill that readers in 1835 needed, and that we still need today.
