Pareidolia: (noun) /pærɪˈdoʊliə/ — The tendency to interpret a vague stimulus as something known to the viewer; such as interpreting marks on Mars as canals or seeing shapes in clouds. From the Greek para- (“beside,” “with,” or “alongside”—meaning, in this context, something faulty or wrong (as in paraphasia, disordered speech)) and eidolon (“image”; the diminutive of eidos (“image,” “form,” “shape”)).
Pareidolia is something that I addressed in my “Pareidolia – The Face on Mars” post in January 2009. In this post, however, I’ll be addressing a different twist on pareidolia that has a different genesis given the modern age of computers, where everyone with an internet connection can be an armchair geologist.
In this particular case study, I will not be talking about Richard Hoagland and his glass cities on the moon and Mars, but rather a more obscure person, Andrew Basiago, of his self-made “Mars Anomaly Research Society.” In 2008, he put out a “research paper” entitled, “THE DISCOVERY OF LIFE ON MARS,” with the first sentence of the abstract being five simple words, “There is life on Mars.”
His evidence? Read further to find out …
What Does Basiago Say He Found, in General?
Basiago is a lawyer and self-described “amateur scientist.” In late 2008, he made headlines by complaining that National Geographic was refusing to publish his work. The following quote is from his press release:
“I was astonished by what I found,” he said. “There, on the Red Planet, were beings in blue bodysuits and the abstract artwork of a Martian civilization. I was looking at the first evidence of life beyond Earth!”
In his letter to the National Geographic Society, the lawyer writes that careful evaluation of PIA10214 reveals “a cosmic treasure trove of pictographic evidence of life on Mars, including humanoid beings, animal species, carved statues, and built structures.”
According to Basiago, the humanoid beings photographed in PIA10214 have bulbous heads and elongated bodies, like the extraterrestrials described in alien contact accounts. Some have two arms and legs like human beings, while others have multiple appendages and segmented or larval bodies, as if they are human-insect hybrids.
The original image in question can be found here.
A Famous Photo
This photograph, or panorama of photographs, from Mars was taken by the Mars Exploration Rover (MER) “Spirit” during the last few months of 2007. It is within the Gusev Crater on Mars on the plateau that NASA has named, “Home Plate.” What makes this photograph interesting is that it itself caught the news cycle due to a fairly “obvious” piece of pareidolia, the “Big Foot” on Mars.
If you download the full version of the panorama from NASA, the “Big Foot” is located about 30″ down, 12″ over (2150 px down, 850 px over to the right). Below is a FULL-RESOLUTION version of just that section. Note that the figure itself is about 37 px tall and 18 px wide. At full resolution. And, it really does look like a person sitting with a hand resting on one knee.
However, with MER Spirit having photographed well over a million rocks on the planet, some are bound to look like something that we’re familiar with. Just like the cloud I saw today looked a lot like Mr. Spock.
While the image of “Big Foot” on Mars garnered some press on its own and made the rounds on Coast to Coast AM, it quickly came out that the rock in question was just a few inches tall and it fairly quickly dropped from the public consciousness.
Expanding Beyond 100% Size
The etymology of the word “pixel” dates back to the 1960s, when it became an abbreviation for “picture element.” In other words, the smallest part of a picture. The smallest “piece” of information that was recorded. A pixel cannot be subdivided into more than one pixel to yield more data because it simply does not exist in the image.
And yet, graphics programs have no problem expanding an image beyond that 100% scale, to make 1 pixel into 2, 3, 4, or more. Software does this through a variety of algorithms, and it may really look like it has smoothly added information to the image, but it has not. It has also introduced artifacts through the expansion process that were not previously there. If, for example, you expand a photograph to 250% its original size, and then you shrink it back to the original 100%, you will not have the same photograph you started with, and you will have lost a little bit of information.
This basic concept is not something that Basiago seems to understand. He took NASA photograph PIA10214 and blew up various parts of it, stretching objects that may have originally been only 5 pixels tall and 7 pixels wide into something 50x that size. In other cases, he has stretched the aspect ratio, making the image much wider or taller than it should be if given a simple expansion.
Let’s look at two examples. In the example below, Basiago describes as: “These and other animals on Mars defy classification by any known system on Earth. We would include among the new forms of fauna on Mars the animal whose giraffe-like head can be seen peering from behind the cliff literally within feet of Spirit. This animal has red lips, a patch of blue beneath its bulging eyes, and a crest atop its head like some dinosaurs. Even the most spirited disinformation that this report will inspire will have difficulty finding a mundane, non-biological explanation for The Spying Giraffe.”
In this second example below, Basiago describes: “Maybe the creatures seen – including both living plesiosaurs (left) and dead ones (right) – are plesiosaurs that survived on Mars the extinction that befell plesiosaurs on Earth.”
I’ve been kind with these examples. In the many, many photographic blow-ups that he includes in his paper, these are among the best few that actually sorta kinda look like what he claims. However, any normal reader with pretty much any amount of common sense can tell that these are simply rocks. Or, at the very least, one would need higher-resolution photographs to really tell anything, as opposed to just blowing up a low-resolution image (e.g., the far-right one in the first example).
What automatically enters my mind when someone claims they see something anomalous in a photograph, or that they see “data’s head” on the moon or subway systems on Mars, I first think “pareidolia,” and my second thought is, “what’s the resolution?” In other words, is the object they’re describing actually fully resolved, or are they stretching the pixels to bring out something that’s not really there? As was the case in the examples of “amateur scientist” Andrew Basiago, both of these were at play, and what he was really looking at was simply a bunch of rocks.
