Could there be Life on Mars?

Life on Mars. For thousands of years, scientists have been studying whether there is life on Mars. Space experts now point out that there is huge frozen water beneath Mars, and water is the source of human survival. With the continuous development of science, Mars may become the second earth suitable for human existence.

Life on mars

By 1976, the green villain on Mars was no longer legendary, but researchers conceived of a kind of slow growth that adapts to the cold

Astrobiology has become a university discipline. In theory, Mars has the ability to make life. Mars has the largest volcano and canyon in the solar system. It is like a drained ocean riverbed with a significant coastline. River beds, alluvial plains, fossil lakes, and valleys left by the floods can be found on Mars. Its atmosphere is mainly composed of carbon dioxide.

In 2014, a scientific research team involving Chinese scientists made a new discovery, which inspired "Mars fans". The research results published in the international academic journal "Meteorology and Planetary Science" stated that "from one

Sultry temperatures and siege heat are not the only obstacles to life, Slip said.

Another problem is the large amount of carbon dioxide in the original atmosphere. Carbon dioxide does not dissolve in the lava, so it bubble up in the magma ocean, creating the so-called escape greenhouse effect, Slip said.

If the planet is to become habitable, most of the carbon dioxide must disappear.

Slip said that about 4.4 billion years ago, when the tectonic plates began to move, this activity began gradually.

As the plates move, carbon dioxide begins to enter the mantle in a process called subduction, a process in which one plate moves below the other and sinks into the mantle layer.

At that time, the ocean of liquid water also began to condense. Once the earth was sufficiently cooled and most of the carbon dioxide entered the mantle, life began to appear. Slip said that the opportunity was that life came from Mars to Earth.

"We know that life already appeared on Earth 3.9 billion years ago, but Mars may have been more habitable than Earth long ago," Slip said.

"For hundreds of millions of years, Mars is not a nasty place. It has liquid water. But if life evolved on Mars, rocks would be hit by asteroids from time to time. At some point, rocks from Mars May have hit the earth. "

If the Earth's environment happened to be very suitable for life development at that time, the Martian rocks may be the first beginning of life on Earth.

But this is only a theory and can be tested. However, unlike Earth, there are ancient geological records on Mars, but it is very difficult to detect them.
