Why are scientists afraid of Titan rich in liquid water?

Although scientists have discovered at least dozens of terrestrial planets in the vast universe for nearly half a century, and speculated that the environment above is similar to that of the earth, it is very likely that life has been born. But because of the limited speed of human beings, we have no way to get there at all. So for humans, the current focus of detection is still in the solar system. Like the 1970s? Before the 1980s, scientists in the United States and the former Soviet Union regarded Venus as the Earth's? Sister planet? Scientists are eager for Venus to become our new home.

However, because the situation of Venus is so bad, since 1990s, scientists have gradually turned their attention to another livable planet in the solar system? On Mars, compared with Venus, although the present situation of Mars is also very bad, scientists firmly believe that only by transforming it in the future can Mars become a new home for mankind. Today, the US Mars program is also in full swing. It is predicted that within 20 years, the first batch of human space immigrants will successfully land on Mars. According to the current development speed, it is definitely a lifetime series.

Similarly, with the deepening of the exploration of the solar system, scientists have discovered some satellites that were previously ignored by us, and there are miracles in them. For example, Titan, as the second largest satellite in the solar system, is also the largest of Jupiter's many satellites. As early as 1655, scientists discovered it, but due to the limited level of science and technology at that time, it was not until recent years that Titan began to be gradually known to us.

The most special thing about Titan is that it is also the only satellite in the solar system with a strong atmosphere. However, unlike the main gas in the earth's atmosphere is oxygen, Titan's atmosphere is full of methane, but this has not reduced scientists' interest in it. On the contrary, many scientists believe that there is likely to be life on Titan, and methane is the basis for their survival, just as oxygen is for life on earth.

At the same time, Titan is very similar to the early earth, and some scientists also believe that Titan may be used as a reference to help us understand the early situation of the earth and the mystery of the birth of life on earth. To scientists' surprise, there is still liquid water on Titan, but it is also full of methane, and it will rain with methane. So, for human beings, is Titan very suitable for our survival? The answer is no, Titan's methane water is so terrible that humans can't get close to it.

This is because Titan's liquid methane has little buoyancy. For example, when we swim at the seaside, we can float easily. But on Titan, even if we use some floating equipment, we will sink to the bottom of the sea at the moment we enter. Imagine, who would make fun of his life? However, life may already exist in Titan's methane ocean. I hope scientists can uncover the truth of Titan as soon as possible, uncover the magic of cosmic life for us and prove that we are not alone!
