The US NASA once published a message saying that the Perseverance probe found organic matter on the surface of Mars .
When everyone knew the news, they were extremely excited.
We all know that organic matter is a necessary prerequisite for making up life.
. The detector finds organic matter on the surface of Mars, which will further indicate that there is a high probability that life will exist on Mars.
or, long ago, life existed on Mars.
Today we will talk about new discoveries about life on Mars, further speculate whether there is life before or now on Mars, and then speculate whether there is alien life in the universe.
All phenomena indicate that on a dead planet like Mars, life is likely to exist.
So think about it, if life exists on Mars, then civilization will not seem strange in such a vast universe.
Mars is the closest planet outside the Earth's orbit.
If you arrange according to the position of the eight planets from the sun, it is Mercury, Venus, Earth, Mars, Jupiter , Saturn , Uranus , Neptune , Neptune .
The two adjacent planets on Earth are Venus and Mars.
Venus is closer to the sun than our earth, so its surface temperature can reach above 400℃, which is completely unsuitable for most of the life on our earth, but Mars is different.
Mars can be regarded as the planet closest to the Earth in the solar system.
Its volume is not too large, with a diameter of 6779km, which is about half the diameter of earth .
and its mass is also 1/9 of the earth's mass.
Mart's closest position to the sun in its orbit is about 207 million kilometers, the farthest position to the sun is about 249 million km, and the average distance is about 228 million km.
If it is analyzed according to its distance from the sun, Mars is also in a very livable position.
Scientists have discovered that although Mars is a deadly planet, the traces of the riverbed being washed away in the photos sent back by the probe can be clearly seen?
This kind of erosion trace is exactly the same as the erosion trace of our earth's riverbed.
Therefore, most people speculate that Mars is likely to have really existed in ancient times a long time ago, and that these water resources are located so large that they can cover half of the northern hemisphere of Mars.
Let’s all imagine what kind of scenario would it be if these water resources could be preserved until now?
It is very likely that our humans on Earth have already achieved radio communication with Martians and .
Unfortunately, long ago, Mars suffered a huge impact event . The impact intensity of
directly hits the core of Mars.
causes Mars to lose its magnetic field. Under the erosion of solar wind , Mars gradually lost its original atmosphere, and the surface water could not be locked and slowly flowed into space.
But it makes us feel lucky that on the surface of Mars, although a large area of ocean is lost, scientists can still observe that there are a lot of water resources.
The water ice in the North and South Poles forms a large area of white pole cover.
Although the temperature of Mars is the closest to the temperature of the earth's surface, its average surface temperature reaches minus 63℃.
Therefore, under such cold temperatures, water resources can only exist in solid form.
2018 Scientists also discovered liquid water lake on the surface of Mars, although this liquid water lake is located in the underground rock formations of Mars.
But this is also a new discovery that is very conducive to the detection of life on Mars.
my country's Zhurong rover has also discovered the existence of water-containing minerals.
In fact, as early as 2014, scientists discovered that there is a high possibility that there are a large amount of water resources inside Mars. If there is indeed a lot of water inside Mars.
So can we speculate like this: there is a cave somewhere on Mars.
A large amount of liquid water resources can be found inside this cave.
In a place rich in liquid water resources, there are also living organisms. These living organisms hide here in order to escape the disaster on the surface of Mars. The Martians living here can avoid the cosmic radiation on the surface of Mars.
