The Cydonia region on Mars has captured the imagination of scientists and the public since the discovery of unusual formations that appear artificial in nature.
The Face on Mars
Discovered in 1976 by NASA's Viking 1 mission, the "Face on Mars" is a mesa in the Cydonia region that resembles a human face when viewed from above. While initially dismissed as a trick of light and shadow, higher resolution images have continued to show intriguing facial features that some researchers believe may be evidence of intelligent design.
The Cydonia Pyramids
Near the Face structure, researchers have identified pyramid-shaped formations that appear to have geometric precision. These structures are arranged in patterns that some analysts suggest may have astronomical significance, similar to ancient monuments on Earth like the Giza pyramids.
The Potential City Complex
Beyond the Face and Pyramids, the Cydonia region contains what some researchers call "The City" - a collection of formations that appear to be arranged in a geometric pattern consistent with urban planning. These structures have sparked debate about whether they could be remnants of an ancient Martian civilization.

Image Comparison: Then vs Now
Compare the original 1976 Viking image of the Face on Mars with higher-resolution images captured by later missions. Slide the divider to reveal how our view of this mysterious formation has evolved over time.
The image on the left shows the original Viking 1 photograph from 1976 that sparked worldwide interest in the "Face on Mars." The image on the right shows the same formation captured by the Mars Global Surveyor in 2001 with much higher resolution and different lighting conditions.
Scientists explain that the face-like appearance in the original image was due to the low resolution, specific lighting conditions, and human tendency to recognize familiar patterns (pareidolia). However, some researchers continue to point out potentially artificial characteristics that remain visible even in higher-resolution imagery.

Cydonia Discovery Timeline
Viking 1 Discovery
NASA's Viking 1 orbiter captures the first images of the "Face on Mars" in the Cydonia region, showing what appears to be a humanoid face looking upward.
Mars Global Surveyor
Higher resolution images from the Mars Global Surveyor provide more detailed views of the Face and surrounding structures, showing more detail but maintaining some of the facial features.
Mars Odyssey Mission
The Mars Odyssey mission provides thermal imaging of the Cydonia region, revealing interesting temperature variations in the structures that some researchers suggest could indicate artificial materials.
Mars Reconnaissance Orbiter
The highest resolution images to date are captured by the Mars Reconnaissance Orbiter's HiRISE camera, providing unprecedented detail of the Cydonia formations.
Ongoing Research
Scientists and independent researchers continue to analyze the Cydonia region, using advanced imaging techniques and comparing the structures to both natural and artificial formations on Earth.
Mars Anomalies: Beyond the Face
The Cydonia region contains numerous intriguing formations beyond the famous Face. Explore these additional anomalies that have captured researchers' attention.
The D&M Pyramid
Located approximately 20 kilometers south of the Face, the D&M Pyramid (named after its discoverers DiPietro and Molenaar) is a five-sided structure with apparent geometric precision. Some researchers have noted that its angles and proportions appear to encode mathematical constants.
The Fort
This rectangular formation in Cydonia has been nicknamed "The Fort" due to its apparent right angles and straight edges. The structure shows what some interpret as walls and internal chambers, though NASA attributes these features to natural geological processes.
The Cliff
This unusual formation appears to be an extremely straight cliff face with regular indentations along its length. Some researchers have suggested these could be openings or entrances to an artificial structure, while others point to similar natural formations on Earth created by geological fracturing.
The Tholus
The Tholus is a dome-shaped formation with what appears to be a spiral pattern on its surface. While NASA classifies it as a natural hill or small mountain (the term "tholus" is used in planetary geology for such features), some researchers point to the unusual regularity of its spiral pattern as potentially artificial.
Note: While these formations have sparked significant interest in the research community, scientific consensus generally attributes them to natural geological processes combined with particular lighting conditions and the human tendency to recognize patterns (pareidolia). However, ongoing analysis with increasingly sophisticated imaging technology continues to fuel debate about their origins.

Frequently Asked Questions
What exactly is Cydonia?
Cydonia is a region on Mars located in the planet's northern hemisphere, in the transition zone between the heavily cratered southern highlands and the smooth northern plains. It's approximately 950 km from the Martian north pole and is most famous for containing several unusual surface features, including what appears to be a humanoid face and pyramid-like structures.
Is the Face on Mars real or just a trick of light and shadow?
The Face on Mars is a real geological formation, but its appearance as a humanoid face has been a subject of debate. Initial low-resolution images from 1976 showed what strongly resembled a face. Later, higher-resolution images revealed more details that some interpret as natural erosion patterns, while others point to persistent facial features that remain visible even in detailed imagery. The debate continues in scientific and research communities.
Why do some researchers believe these structures are artificial?
Some researchers point to several characteristics that they believe suggest artificial origin: the geometric precision of the pyramid structures, the bilateral symmetry of the Face, the alignment of structures in relation to Martian north, and the mathematical relationships between the positions of various formations. They also note that natural processes typically don't create such complex, organized patterns.
What does NASA say about the Cydonia formations?
NASA's official position is that the formations in Cydonia are natural geological features shaped by erosion, wind, and other natural processes. They attribute the face-like appearance in the original images to pareidolia (the tendency for humans to see familiar patterns, like faces, in random stimuli) combined with the low resolution of the 1976 Viking images.
Could Mars have supported an ancient civilization?
Scientific evidence shows that Mars once had liquid water on its surface and a thicker atmosphere, potentially making it habitable for microbial life billions of years ago. However, there is currently no scientific consensus supporting the existence of an advanced civilization on Mars. The debate about the Cydonia structures continues to inspire research into Mars' past and the possibility of ancient life on the Red Planet.
