Back in Time Today
In the roaring 1920s, the world was gripped by flapper fashion, jazz music—and a surprisingly widespread belief that Mars was home to an advanced alien civilization. Fueled by early radio broadcasts, new telescopic discoveries, and the imagination of scientists and science fiction writers alike, millions genuinely thought we were not alone. Here are 17 wild facts about the Mars craze that swept the globe nearly a century ago.
1. The “Canals” That Started It All
In 1877, Italian astronomer Giovanni Schiaparelli observed lines on Mars that he called “canali.” American audiences mistranslated this as “canals,” suggesting artificial structures—possibly constructed by intelligent beings. This misinterpretation fueled speculation about advanced civilizations on Mars.
With telescopes not powerful enough to resolve the planet’s surface, the notion of canals captivated the public imagination. People were fascinated by the idea of intelligent Martians designing massive structures for irrigation or transport.
Schiaparelli’s observations were intended to be simple descriptions, yet his “canali” became a cornerstone for Martian myths, inspiring endless debates and theories.
2. Percival Lowell Took It to the Next Level
Percival Lowell, a wealthy American astronomer, passionately believed the canals on Mars were evidence of a dying Martian race struggling to survive. His writings in the early 1900s ignited the public’s imagination and fascination with Mars.
Lowell built his own observatory in Flagstaff, Arizona, to study the Red Planet, dedicating his life and resources to this pursuit. His detailed maps and theories about Martian canals mesmerized many.
Although his ideas were later debunked, Lowell’s fervor for Mars helped cement the planet in popular culture, influencing future generations of both scientists and science fiction writers.
3. Scientists Didn’t Immediately Dismiss the Idea
In the early 1900s, the concept of life on Mars wasn’t immediately dismissed by scientists. While cautious, many astronomers entertained the possibility, though most stopped short of claiming a “super race” existed on the Red Planet.
This era marked a time of discovery and curiosity, with scientific minds open to exploring new ideas. Theories about Martian life were discussed earnestly in scientific circles.
Despite lacking concrete evidence, this open-mindedness contributed to the era’s fascination with Mars, inviting speculation and wonder about what secrets the planet might hold beneath its mysterious surface.
4. Popular Newspapers Spread the Martian Hype
Major newspapers in the 1920s regularly ran headlines about “life on Mars,” treating the topic as a developing news story rather than fringe speculation. This journalistic enthusiasm helped fuel public curiosity and belief in Martian civilizations.
Articles often featured dramatic theories and bold claims, captivating readers with the potential for life beyond Earth. The sensationalism fed into the era’s broader appetite for adventure and discovery.
As a result, the Martian craze wasn’t just confined to scientific circles; it permeated popular culture, shaping public perceptions and keeping the idea of a super race on Mars alive in the public consciousness.
