Mars Flips Us The Bird

Is that a bird? Yes, I can see a bird! A bird on Mars! Aliens must have created it to send us a message! Actually, no, it’s a curiously shaped dune on the Martian surface. My subconscious brain has just processed a familiar shape and my conscious brain did the rest.

Captured by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO), this dune is located in the north polar sand sea (commonly referred to as the “north polar erg”) and it is undergoing the process of defrosting. As the Red Planet’s northern hemisphere is entering springtime, the increased intensity of sunlight is causing carbon dioxide ice (and some water ice) to sublimate into the atmosphere. The ice can be seen as frosty white patches, whereas the dark patches are likely freshly deposited particles from carbon dioxide geysers erupting from the surface.

This is all well and good — how amazing it is to be witnessing the onset of Martian spring at such high resolution! — but it’s the bird head (possibly some kind of falcon?) that drew me into reading about this fascinating HiRISE update in the first place.

This is a fantastic example of pareidolia, a psychological phenomenon that makes us see familiar images in apparently random assortments of shapes. It’s the same phenomenon that makes us see the shapes of bunnies in clouds and the face of Jesus in burnt toast. Interestingly, the HiRISE folks didn’t point out the bird head in this particular photo, but considering they recently brought us the “Elephant On Mars,” I’m thinking this is no coincidence. Those sneaky scientists. During the fun elephant escapade earlier this month, HiRISE scientist Alfred McEwen decided to use the “elephantolia” as an opportunity to teach some really cool Martian geology and make us aware of Martian pareidolia. (Apparently an elephant couldn’t outrun an ancient flood of Mars lava, who knew!)

Right around the same time, images were released of the shape of a parrot in a Martian mesa. Unfortunately, the parrot researchers weren’t joking — they seem to wholeheartedly believe some form of alien intelligence is involved. But as demonstrated by the new HiRISE image, the parrot research is totally based on pareidolia (or “parrotolia”). They saw a parrot, and they have spent years proving it’s a parrot. The logical misstep is astonishing.

In fact, I found this whole thing so astonishing that I plucked this particular parrot to death in my most recent Al Jazeera English op-ed. And yes, I used Monty Python to emphasize my point.

Many thanks to Jason Major for pointing out the HiRISE pareidolia!
