Recently, the European Space Agency (ESA) released photos taken on Mars, in which a surprising phenomenon appeared, that is, a place called the "Inca Ancient City" on Mars, where dense spiders were found.
We all know that there is no life on Mars, and since there is no life, where did these spiders come from?
Why are there ruins of ancient cities on Mars?
The ruins of an ancient city on Mars are located in the South Pole region of Mars, called Inca City, officially known as the Angustus Labyrinthus.
Discovered in 1972 by NASA's Mariner 9 probe, this ancient city is named after its intersecting valleys or ridges, reminiscent of the ancient Inca city and a labyrinth. Its specific location is at 81.68° south latitude and 63.25° west longitude on Mars.
In 2002, the Mars Global Explorer rover explored the ancient city further and found that the Inca was part of a circular structure with a diameter of 86 kilometers.
This means that the location of the ancient Inca city was once a crater. And the ancient Inca city is located in this huge round pit.
According to previous detection data, under the impact of huge meteorites, the crater is generally relatively flat, and it is difficult to appear such a complex geological structure, and it is also a mystery how it was formed.
Scientists speculate that perhaps when the meteorite hits, the energy released by the impact is too large, causing the Martian crust to rupture, causing magma in the Martian mantle to flow along the cracks.
When the magma cools, it becomes a hard, erosion-resistant rock wall. Over time, the surrounding sand and rocks were blown away by the Martian dust storm, leaving only the magma walls, which are what people see today.
Of course, this statement is only speculation by scientists, which is also the most likely reason for the formation of the ancient Inca city on Mars, as for how it was formed, people still need to further observe and explore.
Why did the ancient Inca city on Mars gather so many spiders?
We all know that Mars is a dead star, and its core of Mars stopped rotating 3.9 billion years ago, and because the core stopped rotating, it could not generate a magnetic field.
After losing the protection of the magnetic field, the planet, which was originally filled with water, evaporated under the blowing of the solar wind. In addition to the evaporation of water, there is no atmosphere left on Mars, only a small part, and heavier carbon dioxide molecules remain on the surface of Mars, so the Martian atmosphere is very thin.
In addition to the above two points, the loss of protection from the magnetic field, allowing the solar wind and cosmic rays to rage unscrupulously on the surface of Mars is a disaster for any life.
Therefore, scientists believe that life cannot be born in such a harsh environment, and even if life is born, it is impossible to survive in such a harsh environment.
However, with the deepening of Mars exploration, there is more and more evidence that there may be some life below the surface of Mars, and the methane gas released by it has been detected by the Curiosity rover many times.
In addition, in the South Pole region of Mars, a large amount of water ice has gathered, and these water ice will absorb the heat of magma in the part close to the magma, forming an underground lake, and these lakes will be a hotbed of life.
If Mars is the most likely place to have life, or if there is life on Mars, then these Martian lakes with warm ground are the most likely places to find life.
So could the spider found in the ancient Inca city on Mars this time be Martian life, and if not, what is it?
What exactly was the spider in the ancient Inca city of Mars?
Judging from the photos taken by the European Space Agency, these dense black spots, surrounded by slender "legs", are all gathered together, very similar to the newly hatched spiders on Earth.
And these spiders are gathered near the ancient Inca city on Mars, because the ancient Inca city itself is very surprising, and these spiders gather in its vicinity, which can't help but make people think.
These photos were taken by the Mars Express in orbit, and you can't look at these photos with the eyes of the earth, those seemingly dense little spiders are actually very large.
According to the proportions, it was found that the smallest ones had a diameter of 45 meters, and the largest ones were even about 1,000 meters, which was obviously beyond the scope of life, and even if there was such a large life, the desolate Mars could not provide so much food.
Although it seems, these spiders seem to be very active and active. In fact, all of these spiders are stationary, and the reason for their formation is a phenomenon unique to Mars.
As mentioned earlier, the vast majority of the Martian atmosphere is carbon dioxide, with a content of more than 95%. Due to the harsh climate on Mars, the temperature difference between day and night is huge, with the highest temperature reaching 27 °C and the lowest temperature in the polar regions reaching -143 °C.
The ancient Inca city of Mars is located in the Antarctic region, and the temperature of carbon dioxide reaches -78.5°C before it solidifies and turns into dry ice. When Mars spring comes, after the temperature rises, the dry ice underground will sublimate into carbon dioxide gas, and in the process of gas expansion, energy will be released, which will blow up the ice on the surface, forming dense black spots with cracks, which look like "spiders".
In fact, there is also this phenomenon on the earth, near the Arctic Siberian region, there is also a large amount of methane gas underground, as the temperature of global warming increases, the release of methane gas in the process, will also release a large amount of energy, blowing the surface out of the potholes.
Therefore, sometimes I have to sigh at the miracle of nature, under various coincidences, various cosmic wonders have been formed, and among all the cosmic wonders, the most amazing thing is that various chemicals are combined together to give birth to life, and then give birth to human beings.
