Chapter 1836: The Magical Ground of Titan
Zhao Zhongyao saw that the two children were quite sensible, so he said again, ‘Actually, you can make some videos. Doesn’t this mean that you have brought these magical little celestial bodies back to the earth! ’
Zhao Zhongyao said that Feifei and Tiantian felt very reasonable. In fact, why really bring these small celestial bodies back to the earth? Just making some videos does not mean bringing these small celestial bodies back to the earth.
In this way, Feifei and Tiantian took out video cameras and cameras, and took some videos and photos respectively.
Originally, Feifei and Tiantian were responsible for shooting the wonders of outer space, but now that they both do this, they can be regarded as doing their job.
When Feifei was similar to what Tiantian shot, Zhao Zhongyao flew out of Saturn's halo again in his spacecraft, and started flying towards their destination, Titan.
Soon, they flew near Titan.
Titan is a very special planet, and it can be said that it is the planet most likely to give birth to life.
When it was a few kilometers away from the surface of Titan, everyone saw that there were many lakes on the surface of Titan.
Everyone was happy when they saw these lakes.
Feifei said excitedly, ‘Dad, look now. There are many lakes on the surface of Titan, which look very much like our earth! ’
Tian Tian said happily, ‘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 lakes on earth. But these lakes are not water. Zhao Zhongyao didn't say what exactly are in these lakes.
After hearing what Zhao Zhongyao said, Feifei and Tiantian were very puzzled. Feifei looked at his father and asked, ‘Dad, these lakes are not water, what is that. ’
At this time, Zhao Zhongyao looked at them and said, ‘These lakes are not water, but methane, liquid methane. ’
Feifei and Tiantian were surprised when they heard what Zhao Zhongyao said. Feifei said, ‘what, these lakes are all liquid methane! ’
Tiantian also said in amazement, ‘is the entire Titan lakes methane lakes! ’
‘Yes, there are some methane lakes on the entire planet Earth. Although Titan may also have water on its surface. However, because the surface temperature of Titan is too low, it is impossible for water to exist in a liquid state. Said Zhao Zhongyao.
After listening to my father, Feifei and Tiantian understood why there was some liquid methane in these lakes.
After Zhao Zhongyao and Feifei Tiantian talked about these liquid lakes, they drove the spacecraft again and landed on the surface of Titan.
The surface of Titan is very cold, about minus 170 degrees. Although many lakes can be seen, they are all liquid methane lakes, not real lakes at all.
The main reason why the surface of Titan is so cold is because the surface of Titan has a thick atmosphere. This layer of atmosphere is mainly composed of nitrogen.
Due to the dense atmosphere on the surface of Titan, this prevents sunlight and Saturn radiation from entering the surface of Titan. As a result, the surface of Titan is extremely cold.
But no matter how cold the surface of Titan is, life may exist. Because life will not be on land, only in these liquid methane lakes.
Although the surface of Titan is very cold, but inside these liquid methane lakes, it may not be so cold.
Because there are 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 Titan’s surface does not have oxygen. But oxygen is not the only condition to sustain life. Many ancient bacteria on the earth don't need oxygen. They even hate oxygen very much.
Like some anaerobic bacteria on our planet, they don't like oxygen. And their excrement may be oxygen.
Therefore, the oxygen on our planet may be the excrement of anaerobic bacteria, because they constantly eat some hydrocarbons, and then emit some oxygen.
The surface of Titan is actually equivalent to what the Earth looked like three billion years ago. The earth at that time was far from being so warm again. Because at that time, there was no such thick atmosphere on the earth.
The reason why the earth is so warm is that there is a layer of atmosphere above the earth, especially there is 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 large greenhouse. The greenhouse effect can be produced on the earth, and the surface of the earth has a warm environment suitable for life.
Although there is also a thick layer of atmosphere on Titan, not only does this layer of atmosphere not make Titan a greenhouse, on the contrary, it makes Titan a closed system that isolates external radiation.
In this way, there is an anti-greenhouse effect on Titan. In this way, the temperature above Titan is very low. Unable to adapt to the survival of a large number of lives.
It's just that Titan is a very large satellite. There may be some places on the surface of this satellite with relatively high temperatures. The temperature of minus 170 degrees 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 is volcanic eruption on Titan's surface, it means that this is a very active planet. As long as it is a planet with volcanic eruptions, life may exist.
The existence of 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 life is possible.
The emergence of life was originally born in dire straits. If there is no water, there can be no life. If there is no fire, there is actually no life. In fact, one cannot just say that water is the source of life, fire may also be the source of life.
Just like Venus, a planet that is like on earth, doesn't it also have life?
So, even if the surface of Titan has a very low temperature. There is no oxygen on it, but there are some harsh environments such as liquid methane lakes, but it is also possible to give birth to life.
Now our scientists, although they don’t know much about Titan. However, scientists have placed high hopes on this satellite. Scientists believe that there must be life on Titan.
