"What the hell are aliens in?Why haven't we found it for so long?Could it be that we are the loners of the universe?”
Since birth, human beings have a nature of exploration, which was vividly expressed in the Age of Discovery.
Navigators, both East and West, are passionate about discovering new continents, whether for wealth or curiosity, the human desire to explore is always endless, and soon our little earth is not enough to play, except for the depths of the ocean and a bit mysterious, all other places are trodden by humans.
So, human beings set their eyes on the sky overhead, so what is the mystery in the vast starry sky?Could there be life on other planets, or even intelligent civilizations like us, which has ignited human curiosity?
So, in the galaxy on our doorstep, will there be alien creatures?Maybe they're hiding under alien ice, after all, some planets have oceans, and the oceans can be as deep as 100,000 meters.
In such an environment, if there are creatures, they must be super strong and ferocious, and if they encounter humans, it will be a nightmare, just like in the sci-fi blockbuster "Europa Report", being eaten by alien creatures.
The name of the planet indicates that it is the second moon of Jupiter, which is not too far away from us, we can see it with a telescope, but this planet is very strange.
Ordinary satellites have many craters or impact craters, but Europa does not, its surface is a series of deep cracks, like a scar on the planet, and it glows red, as if it is bleeding.
It's like a monster in the universe scratching Europa with its claws, and it's amazing how magical the universe is.
Regarding the planet Europa, humans have been staring at it since the invention of the astronomical telescope, why can a small satellite attract the attention of all mankind?
The main reason is that Europa may have life, and there is a lot of oxygen, and maybe it can be inhabited by humans in the future, so this little satellite is on fire.
Europa's entire planet is covered in a thick layer of ice, like the ice cream outside, that envelops the entire planet, much thicker than the North and South Poles on Earth.
In 1979, when the Voyager probe flew over Europa, it found that the planet was not as simple as we thought, it was more complex than we thought, the core of the whole star was still very hot, and geological activity could often be seen, so there might be a lot of liquid water under the ice.
This idea is very bold, no one thought that under the icy ice layer is actually "water of life", the heat generated by the volcano and the movement of the earth's crust inside the star, so that the temperature of this water is suitable for the growth of organisms, if you think so, then this star only the size of the moon may really have life.
This has changed people's understanding, and some people used to say that this planet is a frozen "death star", and the surface temperature has been minus 163 degrees Celsius, and our life on earth cannot live.
However, now that this statement is outdated, people's imagination has been completely opened, and there are many conjectures about Europa, and no one is sure that there really is an ocean and life
It wasn't until 1997 that the Galileo probe came to the sky above Europa, and researchers were surprised to find that the planet's magnetic poles change almost every five hours, indicating that Europa has a high probability of an ocean.
It turns out that the rotation of the magnetic poles is caused by the movement of the troposphere, and there is a gravitational relationship between them, and if one side moves, the geomagnetism will also move, which gives great support to the theory of the oceanographic school.
There is a lot of physics involved, and I won't say much here, but the appearance of this phenomenon can prove that there may be a thick liquid diversion layer on the surface of the planet, just below the ice, which humans cannot see from the outside.
Moreover, the ocean that can affect the planet's geomagnetism, Europa may have a lot of water, maybe more than twice the amount of the earth, and the depth of the ocean may be 100,000 meters, if there are creatures in it, then the size of this creature is beyond our imagination.
There may be a lot of giant aquatic creatures in the sea of Europa, and if you can go up to this planet in the future to catch a few big fish and sell them back to Earth, you will definitely make a fortune!
As we all know, the current theory of evolution says that most of our creatures evolved from the ocean, and then slowly moved to the land, and finally became intelligent creatures like us.
According to this theory, the ocean is the cradle of life, so Europa's ocean is larger than our earth's, can it evolve Earth-like creatures?
The organisms on our earth are all carbon-based organisms, and the conditions of carbon-based organisms are probably similar, and the formation process is similar, and the highest organisms that can be formed on planets like Europa are carbon-based organisms.
And for carbon-based organisms to survive, they first need water, oxygen and some nutrients, and we can't live without these, so is there oxygen and nutrients on Europa?
According to the research results of the research team of the California Institute of Technology in the United States, the main water in the Europa Ocean is water and sodium chloride, and sodium chloride is the salt we usually eat, which means that the water in the Europa Ocean is similar to the seawater on Earth, but the salt ratio is different.
The ocean is the cradle of carbon-based life and the most important part of the birth of life, which is surprising, and even more surprises are yet to come.
By looking at Europa's surface, the Hubble telescope found that the planet is likely to have oxygen, and there is a lot of oxygen, and even a thin atmosphere has formed on the surface of the planet.
So where does Europa's oxygen come from?Why is this planet so perfect?
Thanks to water, Europa is exposed to cosmic rays that pass through the thick layers of ice and reach the liquid ocean below, breaking down water molecules into oxygen, which then passes through the ice and onto the planet's surface, where most of the oxygen remains in the seawater.
Speaking of which, you may feel familiar with it, isn't this the process of the evolution of life on earth that we have learned before?
Europa may also repeat this process, first forming "extreophiles", which are very low-level organisms, near warm submarine craters.
Oceans, oxygen, geological activity, these conditions all meet the needs of this creature, so the possibility of the emergence of this organism is very high. They don't need sunlight, they have a lot to eat as long as they are close to the crater, and they can eat inorganic matter directly, which is what we call "eating soil"!
So if Europa really has creatures, after so many years of evolution, there may already be many kinds of creatures, similar to the marine creatures of our earth, but Europa's ocean is so big, and the creatures that may evolve are bigger and more terrifying
If you think about it along this line, Europa has many species and numbers, and may have formed a stable ecosystem and food chain, so there may be many carnivorous creatures, and creatures in this extreme environment may be more ** than creatures on Earth!
Fish and aquatic insects may be the first to appear, but this is a fisherman's dream, and you're sure to catch a lot of big fish, but be careful not to get eaten
If in the future, human space technology is more developed and can land on this mysterious planet and unveil it, if there are really creatures in the ocean, it will prove that human beings are not orphans of the universe, and there are many partners of alien creatures
There may even be other intelligent civilizations in the universe, they may be backward or advanced than us, and this infinite imagination supports human exploration again and again.
The above is all imagined based on the existing information of mankind, and whether Europa has life or not, a probe must be launched to see if it is alive, otherwise it is all empty talk.
If carbon-based organisms are really found there, it means that this planet is also suitable for human survival, and then it will be able to greatly expand the living space of human beings, and even open the era of human "space colonization"!
At that time, those science fiction movies will no longer be fantasy, but real "documentaries"!
