In the vast universe, there are countless known and unknown stars, planets and satellites , as well as countless celestial bodies and nebulae waiting for us to explore and study. Finding signs of life is the top priority of the current and future scientific community.
In 1655, Dutch astronomers discovered the largest satellite among the 662 satellites of Saturn. Later, after several twists and turns, this satellite was named "Titan", also known as Titan.
The Titans are the descendants of the ancient Greek god of the sky and the goddess of the earth , who once ruled the world. It has a huge body and immense strength. It is not difficult to tell how huge this planet is with this name.
Titan is currently the second largest satellite in the solar system, even larger than Mercury, second only to Ganymede, the largest satellite in the solar system.
So besides being big, what else is unusual about this Titan planet?
Since its discovery, after more than three hundred years and generations of efforts, and the tireless efforts of countless astronomers and scientists, we have been pleasantly surprised to find that this is the most similar to the Earth among the known alien planets, and it is also the most likely to contain life. What are the similarities between
and the earth?
As we all know, the most important things for derivative life are water and atmosphere. Most planets in the universe do not have these conditions. Titan, on the other hand, has a complete atmosphere, nearly 98.5% of which is composed of nitrogen , and the rest is composed of various gases.
Among the currently known planets, Titan is second only to the Earth in gas richness, and its air pressure is more than twice that of the Earth.
These are all necessary conditions for the evolution of life, which means that Titan is very likely to evolve life. Even if it does not exist now, life may exist or evolve in the past and future.
The atmosphere is also the protective layer of the planet in the universe due to solar storms and various celestial bodies impacting . Otherwise, it will be cratered and devastated at best, or it will be wiped out in the universe.
We look into space from a distance through the telescope. Titan is just like the earth, with an atmosphere, lakes, and hills.
However, the landform of Titan is much flatter than ours, and no hills exceeding 50 meters have been found yet. And according to the overall picture of Titan drawn in 2019, the surface of the planet is basically a plain, which is also different from the earth.
But the process of geological evolution of Titan is similar to ours, and it can even be divided into longitude and latitude. According to the drawing, it looks like the Earth of another world.
Through continuous exploration over the past three hundred years, especially in modern times, many countries have sent detectors to try to get close to capture data at close range.
In 2005, the Huygens spacecraft, jointly launched by the United States and Europe, landed on Titan and successfully transmitted back a large amount of precious image data. This was the first time in the history of human civilization that a probe successfully landed on Titan, which is a milestone.
In addition to the atmosphere, many lakes have been discovered on Titan. However, they are different from our regular lakes. Titan is very cold. The temperature of nearly minus two hundred degrees is colder than anywhere on the earth. Due to the temperature, it is difficult to form liquid water, which is mainly composed of methane and ethane .
There are not only methane and ethane lakes, but also methane and ethane oceans. It also rains methane and ethane. It is a very magical world composed of various gases.
Is it feasible to immigrate to Titan?
Since Titan is so similar to us, is it possible to interstellar immigrants in the past?
The answer is no. In fact, currently in human society, only the United States has the ability to launch detectors to it. If it wants to really unveil Titan and immigrate to the interstellar space, there is still a long way to go.
And as mentioned in the previous article, according to the current data, Titan has no liquid water and the temperature is extremely cold. It is impossible for humans to survive on Titan with current technological means.
In the world of Marvel , Titan has become the home of Thanos with powerful capabilities.
Although this is just an animation, it is precisely because of this comic image that the planet Titan has entered people's field of vision and become known to more people.
Is it possible for humans to realize the dream of interstellar immigration?
Of course, as long as we find a suitable planet and successfully solve the problems of gravity, temperature, air pressure, magnetic field, etc., we can achieve large-scale interstellar immigration.
In fact, space travel is now a new travel hotspot, and it has successfully provided services to several rich people with a spirit of exploration, because in addition to requiring strong physical fitness and a spirit of adventure, this service is also very expensive.
It is said that a "spaceship ticket" requires more than 1.5 billion yuan in expenses for the entire journey, and it also requires passing a physical fitness test, plus a lot of physical training , which is still far away from us ordinary people.
China has also actively invested in space travel projects. It is expected to realize suborbital aviation in 2025. The ticket price is expected to be between two and three million yuan. Although it is still very expensive, it is also a "small step for mankind" and a milestone event for my country's aerospace industry.
However, these are just different degrees of space travel. It is too early to realize immigration, because our current technological level has not solved any of the problems that need to be solved for interstellar immigration, and we have not even found a second planet suitable for human habitation.
But exploring the Titan planet and the universe is not only for interstellar immigration, but also for understanding the origin of life, promoting the development of astronomical science, and allowing us to learn more about the mysteries of the universe and alien planets.
Especially in our country, the exploration of Titan has not yet started. The few data we have so far come from images and text data from other developed countries. In this field, there is still a huge gap between us and developed European and American countries.
What we know about the Titan planet now is only a very small part. Science has a long road ahead, and it still requires the efforts of more people. In recent years, our country's investment in both talent and funds in the aerospace and aviation industry has been very huge, and the future is promising.
I believe that in the near future, our country’s aerospace industry will also develop rapidly. Maybe in the near future, each of us will be able to achieve space travel, interstellar travel, and go to Thanos’ “hometown” of Titan to take photos and post them on WeChat!
