Here’s a story about the old days of radio. In 1924, there were all kinds of stories about life on Mars. Might the beings living there be trying to communicate with Earth? An American radio astronomer named David Todd wanted to find out.
He and a partner came up with a way that was supposed to intercept radio signals coming from Mars and then print out the radio waves on paper. There was one catch, though. For this to work, all Earthly radio stations had to fall silent for five minutes at the beginning of each hour for three consecutive days: August 21 to 24, 1924.
And it actually worked. Sort of.
Terrestrial radio silence was achieved, and some radio wave scribbles were captured. Strangely, they resembled a crudely drawn face, something that was dutifully reported in the newspapers. However, Jenkins didn’t believe it meant anything, and he stopped his research, fearful that he’d be branded a kook.
