With the Martian Bigfoot
recently making headlines, Dr. Charles Lintott wrote an article for the BBC
that traces the long history of Martian pareidolia.
Something about Mars makes us see things that aren't really there. It began with early astronomers believing that the surface of Mars was covered with canals. During the 1960s, some astronomers reported seeing signs of vegetation on the planet's surface.
The image below shows (on the top row) the Martian canals. The bottow row (from left to right) is the "face on Mars" taken by NASA's Viking spacecraft in the 1970s; the fossils that NASA researchers claimed to have found in a Martian meteorite in 1996; the recent Martian bigfoot; and the Martian smiley face (also recently photographed).
