The Great Moon Hoax
On August 25, 1835, the New York Sun, a young penny paper, ran the first of six articles announcing that the British astronomer Sir John Herschel had discovered life on the moon. Herschel was real, and he really had sailed to the Cape of Good Hope in South Africa to set up an observatory with a powerful new telescope. Almost everything else was invented.
The articles claimed to be reprinted from the Edinburgh Journal of Science, a publication that had already stopped printing, and credited a Dr. Andrew Grant, who never existed. Readers learned of giant amethyst crystals, lush valleys, unicorns, beavers that walked on two legs, and furry winged humanoids that looked something like bats. Sales of the Sun jumped. According to a later account, a group of Yale scientists traveled to New York to inspect the original reports and was shuffled from office to office until it gave up.
On September 16, 1835, the Sun admitted the series was a hoax. The usual suspect for the writing is Richard Adams Locke, a Cambridge-educated reporter at the paper, and the series is often read as satire aimed at popular writers who speculated about inhabited worlds. Readers mostly laughed it off, and the paper's circulation did not suffer.
Verdict: DebunkedThe Sun itself admitted within weeks that the moon creatures were invented; the source journal had folded and its credited author never existed.
