Chapter 1647: Liquid Methane Lake

Chapter 1837: Liquid Methane Lake
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.
Zhao Zhongyao was driving the spacecraft, and now he reached the surface of Titan. When they are on the spacecraft, they can see the surface of Titan, with many lakes of methane.
Now Feifei looked at Zhao Zhongyao and said, ‘Dad, where should we find the seventh amethyst gem! How do I feel that there can be no life on this Titan side! ’
Feifei felt that life on Titan is unlikely. After all, the entire surface of Titan is covered with methane lakes. How can there be life in such ‘lake water’!
After hearing what Feifei said, Zhao Zhongnian said, ‘Son, don’t say that. Although there is no liquid water on Titan, life is very likely to exist. ’
'why? How can there be life without even water. Feifei looked at his father puzzled and asked.
Zhao Zhongyao said, ‘Life does not have to be where there is water. Even if there is no water, as long as there is some environment where life exists, life is also possible. ’
‘Dad, what you mean is that there is life in these methane lakes. Feifei said again.
‘However, not all lakes will have life, only individual lakes will have life. Said Zhao Zhongyao.
‘Dad, can we find such a lake? Said Feifei.
‘Okay, let’s find it and look on Titan, that lake may have life. After Zhao Zhongyao finished speaking, he piloted the spacecraft again, flying on the surface of Titan.
Just while flying, Feifei looked at Zhao Zhongyao again and asked, "Dad, what the methane lake on Titan looks like, can you tell me something, I want to know Knowledge in this area. ’
After hearing what Feifei said, Zhao Zhongyao said, ‘Okay, let me tell you something about Titan! ’
Next, Zhao Zhongyao told Feifei some knowledge about Titan Methane Lake.
In human exploration of the solar system, the most interesting topic is the "livable" planet! The current aviation technology is still enough to fly outside the solar system, so in the solar system, it is particularly important to have two celestial bodies that are most similar to the earth, one is the planet Mars and the other is the moon Titan!
The topic of Mars has been endless. As mentioned in the previous article, the huge lakes of liquid water found on the bottom of Mars have attracted the attention of the world. The other Titan is not simple. The environment is very similar to the Earth more than 4 billion years ago.
Titan is also called "Titan". Its speciality lies in the atmosphere. It is the only "nitrogen-rich star" in the solar system besides our earth. The nitrogen content of the atmosphere accounts for 98.4%, while the nitrogen content of our planet is 78.1%! And our earth more than 4 billion years ago, the nitrogen content was more than 95%, until the center of the earth ejected water vapor and methane and other substances, oxygen elements gradually increased. In the observation of the Cassini probe, all the surface of Titan is liquid methane, ethane! Many lakes of different sizes are formed, and some are even comparable to small oceans! These small lakes and oceans occasionally emit bubbles.
This discovery was once considered by scientists as a signal of life on Titan. Some scientists believe that microbes or other life forms have been born under Titan’s methane ocean, and bubbles are generated by life activities. Muddy gas. In order to verify the accuracy of this conjecture.
Professor Lane of Harvard University in the United States led his team to conduct simulation experiments. It is to imitate the environment of Titan, and after careful observation, it is found that the atmosphere of Titan contains methane, which will slowly sink to the surface to form a lake over time, but it will contain nitrogen and other elements! The mixture that sinks into the methane lake will undergo a chemical reaction. Nitrogen is released separately to form bubbles, not produced by microorganisms.
However, there is another surprising discovery. In this case, the chemical reaction in the lake will release heat and change the temperature of Titan! The value is very small, and maybe hundreds of millions of years later, it is possible to turn Titan from minus 170 degrees to a suitable temperature.
However, if humans join in, this kind of temperature transformation will become very fast, and it is possible to accelerate the formation of life and even immigrate to Titan, which is even lower than the cost of transforming Mars! Because a large amount of methane contains the three elements of carbon, hydrogen and oxygen, the atmosphere also contains nitrogen, which are the basic elements for life. Carbon dioxide, water, oxygen, etc. are all composed of these elements!
Using radar data from NASA’s Cassini spacecraft, the newly published research proposes a new scenario to explain why some methane-filled lakes on Saturn’s moon, bai Titan (Titan), are covered by hundreds of feet Surrounded by steep edges. These models indicate that warming nitrogen explosions formed basins in the crust of Titan. Titan is the only star in the solar system other than the Earth that is known to have a stable liquid on its surface. But on Titan, astronomers believe that the gaseous methane and ethane hydrocarbons behave as liquids in Titan’s cold climate, rather than pouring down from the clouds as on Earth, flooding lakes and oceans.
Most existing models reveal the origin of the Titan Lake, showing that liquid methane dissolved the moon’s ice base and solid organic compounds to form a liquid-filled reservoir. This may be the origin of a lake with sharp boundaries on Titan. On the earth, a similar body of water formed by dissolving the surrounding limestone is called a karst lake.
New alternative models of some smaller lakes (tens of miles wide) overturned this theory: it was proposed that the liquid nitrogen pockets in Titan's crust warmed, transformed into explosive gas blowing out of the crater, and filled with liquid methane. The new theory explains why some of the smaller lakes near Titan's Arctic, such as Winnipeg, appear to have very steep edges in radar imaging, towering above sea level, and the edges are difficult to explain with karst models.
The radar data was collected by the Cassini Saturn Orbiter, which was managed by NASA's Jet Propulsion Laboratory in Pasadena, California. This is the data collected during the spacecraft's last close flyover of Titan, when the spacecraft was preparing for its last entry into Saturn's atmosphere two years ago.
