Chapter 1836: The Magical Ground of Titan

Chapter 1836 The magical ground of Titan

Zhao Zhongyao saw that the two children were quite sensible, so he said again, 'Actually, you can take some videos, so isn't it equivalent to bringing these magical small celestial bodies back to the earth! '

What Zhao Zhongyao said made Feifei and Tiantian feel very reasonable. In fact, why really want to bring these small celestial bodies back to the earth! As long as you take some videos, it is not equivalent to bringing these small celestial bodies back to the earth.

In this way, Feifei and Tiantian took out their video cameras and cameras, and took some videos and photos respectively.

Originally, Feifei and Tiantian were responsible for filming the wonders of outer space, but now they are doing their part.

When Feifei was about the same as what Tiantian took, Zhao Zhongyao drove the spaceship out of Saturn's halo again, and began to fly towards their destination, Titan.

Soon, they flew near Titan.

Titan is a very special planet, and it can be said to be the planet most likely to breed life.

When you are a few kilometers away from the surface of Titan, you can see that there are many lakes on the surface of Titan.

Everyone was happy when they saw these lakes.

Feifei said excitedly, 'Dad, look quickly. There are many lakes on the surface of Titan, which look very similar to our earth! '

Tiantian also happily said, 'Dad, are there some big fish in these lakes too! '

After hearing what Feifei and Tiantian said, Zhao Zhongyao smiled and said, 'Don't think these lakes are similar to those on the earth. But there is no water in these lakes. 'Zhao Zhongyao didn't say what was in these lakes.

Feifei and Tiantian were very puzzled after hearing Zhao Zhongyao's words. Feifei looked at his father and asked, 'Dad, there is no water in these lakes, what is that? '

At this moment, Zhao Zhongyao looked at them and said, 'These lakes are not water, but methane, which is liquid methane. '

Feifei and Tiantian were very surprised when they heard Zhao Zhongyao's words. Feifei said, ‘What, all these lakes are filled with liquid methane! '

Tiantian was also surprised and said, ‘Are the lakes on Titan all methane lakes! '

'Yes, there are methane lakes all over Titan. Although Titan may also have water on its surface. But because the temperature on Titan's surface is too low, water cannot exist in a liquid state. Zhao Zhongyao said so.

After hearing what their father said, Feifei and Tiantian understood why these lakes were full of liquid methane.

After Zhao Zhongyao and Feifei talked about these liquid lakes every day, they drove the spacecraft again and landed on the surface of Titan.

The surface of Titan is very cold, about minus one hundred and seventy degrees. Although many lakes can be seen, they are all liquid methane lakes, not real lakes at all.

The reason why Titan's surface is so cold is mainly because Titan's surface has a thick layer of atmosphere. This layer of atmosphere is mainly composed of nitrogen.

Since Titan's surface has a dense atmosphere, this prevents sunlight and Saturn's radiation from entering Titan's surface. As a result, the surface of Titan is abnormally cold.

But no matter how cold Titan's surface is, life is still possible. Because life would not be on land, only in these lakes of liquid methane.

Although the surface of Titan is very cold, it may not be so cold inside these liquid methane lakes.

Because there are also some volcanic eruptions on the surface of Titan, the temperature in some methane lakes near these volcanoes may be relatively high. There may be life in these lakes.

Although there is no oxygen on the surface of Titan. But oxygen is not the only condition for life to exist. Many ancient bacteria on earth do not need oxygen. They even hate oxygen very much.

Just like some anaerobic bacteria on our planet, they don't like oxygen. And their excrement may be oxygen.

Therefore, the oxygen on our earth may be the excrement of those anaerobic bacteria, which constantly eat some hydrocarbons and then emit some oxygen.

The surface of Titan, in fact, is equivalent to what the Earth looked like three billion years ago. At that time, the earth was far from being so warm. Because at that time, there was no such a thick atmosphere on the earth.

The reason why the earth is so warm is that there is an atmosphere above the earth, especially a layer of carbon dioxide at the bottom of this layer of atmosphere. It is this layer of carbon dioxide that turns the earth into a big greenhouse. It can cause the earth to produce a greenhouse effect, and it also allows the earth's surface to have a warm environment suitable for the survival of life.

Although there is a thick layer of atmosphere on Titan, this layer of atmosphere not only does not make Titan a greenhouse, but on the contrary, it makes Titan a closed system that isolates external radiation.

In this way, on Titan, there is an anti-greenhouse effect situation. In this way, the temperature on Titan is very low. Unable to adapt to the survival of a large number of life.

It's just that Titan is a very large satellite, and there may be some places on the surface of this satellite that have relatively high temperatures. The temperature of minus 170 degrees we are talking about is just an average temperature. It does not mean that every place on the surface of Titan has such a low temperature.

As long as there are volcanic eruptions on the surface of Titan, it means that this is a very active planet. As long as there is a volcanic eruption

If there is a planet where there is a star, there may be life.

The reason why there is life on the earth is also inseparable from the phenomenon of volcanic eruptions on the earth. It can be said that it is precisely because of the phenomenon of volcanic eruptions on the planet that the existence of life becomes possible.

The emergence of life was originally born in dire straits. Without water, there can be no life. Without fire, life would not be possible. In fact, we cannot just say that water is the source of life, but fire may also be the source of life.

Just like Venus, a planet that looks like hell on earth, doesn't it also have life?

So, even the surface of Titan has a very low temperature. There is no oxygen on it, just a harsh environment like some liquid methane lakes, but it is also possible to breed life.

Now our scientists, although they don't know much about Titan. But this satellite has been placed high hopes by scientists. Scientists believe that there must be life on Titan.
