The human brain is a pattern-matching machine that refuses to quit. Honestly, it’s a survival trait that served us well when we needed to spot a leopard hiding in tall grass, but it’s a total disaster when we start looking at high-resolution photos of a freezing, radioactive desert millions of miles away. People often talk about disturbing images from Mars like they’re evidence of a cover-up, but the reality is actually weirder. It’s a mix of Pareidolia—that's the psychological phenomenon of seeing faces in inanimate objects—and the sheer, crushing loneliness of the Martian landscape.
Mars is empty. It's a dead world.
When you spend hours scrolling through the raw data feeds from the Mastcam-Z on the Perseverance rover or the older ChemCam on Curiosity, you start to see things. Your eyes get tired. The shadows start looking like doorways. A jagged piece of volcanic basalt starts looking like a femur. It's creepy.
The Face on Mars: The O.G. of Creepy Space Photos
We have to talk about Cydonia. Back in 1976, Viking 1 snapped a photo that launched a thousand conspiracy theories. From a low-resolution perspective, it looked exactly like a giant, stone human face staring up into the void. It was haunting. It looked intentional.
NASA scientists at the time basically shrugged and said it was just a mesa with some weird shadows, but the public didn't buy it. For decades, that "face" was the gold standard for disturbing images from Mars. It wasn't until the Mars Global Surveyor flew over the same spot in 1998—and then again in 2001—with much better cameras that the illusion shattered. Without the perfect afternoon shadows, the face was just a pile of dirt and rock. It was a "low-pass filter" trick of the light.

Still, that feeling stays with you. Even knowing it's just a hill, you can't unsee the eyes.
Why Do Rocks Look Like Bones and Body Parts?
The "Martian Thigh Bone" went viral a few years ago. If you look at the raw image from Curiosity, it is unsettling. It looks like a weathered femur, polished by the wind, just lying there in the dust. You almost expect to see a skeleton nearby.
NASA actually had to put out a formal statement about this one because people were getting so worked up. They explained that it’s just an erosional remnant. Mars used to have water. It had floods. Those floods pushed rocks around, and the wind carved them into strange, smooth shapes over billions of years. When a rock is made of different mineral layers, the softer parts wear away faster, leaving behind knobs and joints that look remarkably biological.
It’s just geology. But try telling that to your lizard brain at 2:00 AM.
The "Doorway" on Mount Sharp
In May 2022, Curiosity sent back an image that looked like a perfectly carved entrance to an underground bunker. It was a dark, rectangular opening in the side of a rock face. It looked too straight to be natural. The internet exploded. People were convinced we’d finally found the entrance to some ancient Martian civilization's basement.
The scale is what usually trips people up. In the photo, that "doorway" looks big enough for a person to walk through. In reality? It’s about 12 inches wide and 15 inches tall. It's a tiny crack.
Geologists pointed out that Mount Sharp is full of linear fractures. Mars has "marsquakes." When the ground shakes, these brittle rocks snap along clean lines. This particular "doorway" was just the spot where several fractures met, and the interior block had fallen out. It’s a hole in a rock, not a portal to another world.
The Problem With High-Resolution Loneliness
There is something inherently disturbing about seeing a discarded piece of trash on another planet.
In 2022, Perseverance spotted a piece of shiny, silver material wedged in a rock. It looked like a gum wrapper or a piece of foil. For a split second, your brain thinks, "Who was here?" Then you realize it’s a piece of the rover’s own thermal blanket that tore off during landing.
There’s also the "Spaghetti" photo. A tangled mess of white string-like material was found sitting in a crater. It looked like some kind of dried-out Martian organism or a weird fungus. Turns out, it was just dacron netting from the rover’s entry, descent, and landing (EDL) system.
These are disturbing images from Mars because they represent our own pollution reaching a pristine world. It's a different kind of horror. It’s the realization that we are the only "aliens" there, and we’re already leaving junk behind.
The Dust Devils and the "Spiders" of the South Pole
If you want something that actually looks like a horror movie, look at the Martian South Pole.
There are these features called "Araneiform terrain." From orbit, they look like giant, black, hairy spiders crawling across the surface. They’re huge. Some are hundreds of yards across.
The science behind them is actually cooler than the "alien" explanation. During the Martian winter, carbon dioxide freezes into a solid slab of ice on the surface. When spring hits, sunlight penetrates the clear ice and warms the dark soil underneath. This turns the bottom layer of ice back into gas. Pressure builds up. Eventually, the gas rips through the ice in a massive eruption, spraying dark dust into the air. The dust falls back down in these spindly, spider-like patterns.
It’s a seasonal geyser of dry ice. But seeing a field of ten thousand "spiders" from a satellite view is enough to make anyone’s skin crawl.
The Psychology of Mars Exploration
Dr. Brittney Schmidt, a planetary scientist who has worked on various NASA missions, has often spoken about how our human perspective limits our understanding of these landscapes. We want Mars to be like Earth. We want to find signs of life so badly that we invent it in the gaps between the pixels.

The lighting on Mars is weird. The atmosphere is thin—about 1% of Earth's—which means shadows are incredibly sharp. On Earth, our thick atmosphere scatters light, softening the edges of things. On Mars, a shadow can look like a bottomless pit or a solid object. This high-contrast environment is a playground for Pareidolia.
We also have to deal with "artifacting." Digital cameras, especially those sending data across millions of miles of space, sometimes have "dead pixels" or compression errors. A single black dot in the middle of a flat plain can look like a distant figure standing still. It's just a bit of corrupted data.
Is There Anything Actually Scary?
The most disturbing thing about Mars isn't the "bigfoot" sightings or the "statues" people think they see in the rocks. It’s the silence.
We have microphones on Mars now. Perseverance has captured the sound of the wind. It’s a low, haunting whistle. When you look at an image of a vast, empty valley like Valles Marineris—which makes the Grand Canyon look like a ditch—and you realize that no human has ever breathed that air, and that it has been that way for billions of years... that’s the real "disturbing" part.
It’s the scale of time and the total absence of life.
How to Debunk Martian "Anomalies" Yourself
If you see a viral photo of a "disturbing" object on Mars, there are a few ways to check the reality before joining a cult.
- Check the Scale: NASA usually provides a scale bar or context for the size of the rocks. Most "skeletons" are the size of a pebble.
- Look for the Raw Image: Third-party websites often crank up the contrast and saturation to make things look more "fleshy" or "metallic." Go to the NASA JPL Raw Image library to see the original, untouched file.
- Compare Multiple Angles: The rovers take thousands of photos. Usually, if you look at the same "statue" from a different angle taken five minutes later, the illusion disappears completely.
- Understand the Camera: Understand that "Bayer filters" and "mosaicking" can create patterns that aren't there.
Mars is a graveyard of a planet. It's a place where a world died, its atmosphere stripped away by the solar wind because it lost its magnetic field. Every "face" or "bone" we see is just our own mind trying to populate that graveyard with ghosts.
Real Insights for Future Skywatchers
The next time you're browsing the latest downloads from the Red Planet, keep a few things in mind to stay grounded.
- Trust the Geology: Mars is 4.6 billion years old. Wind and sand can do incredible things to rock over that kind of timeframe. If a rock looks like a spoon, it's because the wind found a soft spot.
- Context is King: A weird shape in isolation is scary; the same shape in a field of ten thousand similar rocks is just a rock.
- Embrace the Weirdness: Instead of looking for "aliens," look at the real weirdness—the blue sunsets, the frozen clouds of dry ice, and the mountain-sized dust devils.
The real disturbing images from Mars are the ones that show just how much work it’s going to take for humans to ever survive there. It’s a beautiful, terrifying, and utterly indifferent landscape. We don't need to invent monsters to make it more interesting.
If you're interested in the actual science of these images, your best bet is to follow the NASA Jet Propulsion Laboratory (JPL) photojournal. They upload the raw data almost as fast as it hits the Deep Space Network. You can see what the scientists see, minus the clickbait headlines. Just remember to bring your skepticism—and maybe leave the lights on.
