The European Space Agency's probe detects “spiders” on Mars Sciences

Images taken by the European Space Agency reveal a phenomenon being born on the Red Planet Spider-like shapes. A recent image taken by the European Space Agency's ExoMars Trace Gas Orbiter revealed a series of formations on the surface of Mars that, at first glance, resemble a group of spiders.

These very strange formations, located in an area of ​​the Red Planet's south pole called the “Inca City”, are caused by ice that, with the transition from Martian winter to spring, releases carbon dioxide, forming channels ranging from 45 meters to 45 meters in length. Kilometers in diameter.

“These small cracks form when spring sunlight falls on the blanket of carbon dioxide accumulated during the dark winter months,” the European Space Agency explained.

“Sunlight turns the carbon dioxide ice at the base of this cap into gas, causing it to accumulate and rupture the upper ice sheets. The gas is released in the Martian spring, pulling the dark-colored material to the surface and penetrating layers of ice up to a meter thick.”

The dark dust-laden gas is released in high columns through cracks in the ice, forming hot springs and depositing on the surface, creating the dark spots seen in the images. These processes take shape Patterns under the ice resemble spiders when viewed from above.

Discovered in 1972 by NASA's Mariner 9 probe, the “Inca City”, also called the Angustus Labyrinth, owes its name to the linear mountain ranges, which were initially thought to be fossilized sand dunes, or the remains of ancient glaciers.

According to the scientific portal “Live Science”, the discoveries of the Mars orbital probe in 2002 indicated the presence of a circular crater 86 kilometers wide, which may have formed after a celestial body collided with it. Geometric ridges can form from accumulated magma after impact.

A classic example of pareidolia

The phenomenon that occurs when our minds deceive us and create us Seeing things that are not there, known as pareidolia. This occurs when we quickly detect familiar patterns that may have evolutionary value in identifying, for example, potential dangers, such as a snake. That's why we sometimes see things that don't exist, like “Martian spiders.”

On Mars, there have been many pareidoles, such as the famous “bear face,” the “space door” captured by the Curiosity rover, and a cat-shaped rock recorded by the Perseverance robot. On the moon's surface, China's Yutu 2 spacecraft found a “mysterious hut” that was actually just a strange-shaped rock.
