Scientists have found that Pluto may have a lot of underground water resources, there may be life

The earth is not only a planet of life, but also a planet rich in water resources. Because the earth is in the habitable zone and has a suitable temperature, there is a lot of liquid water on the surface, accounting for 71% of the earth’s surface area. Water is the source of life. The reason why the earth can give birth to life and human beings is closely related to the rich liquid water resources.

With the help of science and technology, human beings have been looking for liquid water resources of other planets when they go out of the earth to explore the universe. Because scientists believe that the existence of liquid water resources on the planet, the existence of life is also very likely. There are eight planets in the solar system. Besides the earth, Mars and Venus are also in the habitable zone. However, these two planets are completely different from the earth. The surface temperature of Venus is too high to have liquid water.

Mars scientists have found some water ice at the poles and speculated that there may be liquid water under the surface of Mars. Is water scarce in the universe? In the past, scientists thought that water resources may be a scarce resource in the universe. However, with the continuous increase of human cognition of the universe, it is found that non existence in the universe may be universal, and it is not a scarce resource.

We don’t know what’s going on outside the solar system, but in the solar system, water is not scarce. In addition to the earth, there are many other planets with rich water resources, such as the satellites Europa, Callisto and Ganymede of the stars, and the satellites Enceladus and titan of Saturn, which show that there are “traces” of liquid water inside them.

Scientists found that Europa has more water resources than the earth through the data sent back by the probe, which can be called a “water ball” to the letter. Europa is the fourth largest moon of Jupiter. The surface of the planet is covered with a thick layer of ice. Scientists estimate that the ice layer is 50 km deep. Under the ice layer, there may be the largest liquid water ocean in the solar system, with an estimated depth of 80-170 km. The water content is about two or three times that of the earth, which is the most water content object found in the solar system.

In fact, compared with Ganymede, the water content of Europa is much smaller. By studying the tiny shift of aurora on Ganymede, scientists infer that Ganymede has a huge underground ocean. It is estimated that there is a sea of salty water under the ice sheet of Ganymede, which is about 150000 meters thick. The depth of the sea is about 100000 meters, which is 10 times that of the earth’s sea. The content of liquid water may exceed 30 times that of the earth.

In addition to these satellites, scientists have observed that Uranus, one of the eight major planets, may also have a liquid ocean composed of water, silicon, magnesium, nitrogen-containing molecules, hydrocarbons and ionized materials. It is estimated that the total water content is about 9.3-13.5 times the mass of the earth. Recently, by sorting out and analyzing the data about Pluto sent back by new horizons, scientists found evidence of the existence of ammonia on the surface of Pluto, suggesting that there may be liquid water beneath the surface of Pluto.

Pluto is a planet on the edge of the solar system. It was once one of the nine major planets in the solar system. Later, scientists found that it was too small to be regarded as a dwarf planet, so they kicked it out of the planetary family. So now the solar system has changed from the original nine major planets to eight major planets. Although Pluto is no longer a major planet, scientists are paying no less attention to it.

Pluto is one of the important target planets for scientists to study and explore the Kuiper belt. As we all know, there is a very mysterious Kuiper belt on the edge of the solar system, which is composed of countless kinds of celestial bodies, forming a ring around the solar system. It is still a mystery how many celestial bodies there are in the Kuiper belt and what kind of celestial bodies there are. Pluto is a celestial body outside the Kuiper belt.

New horizons is an interplanetary space probe launched by NASA in 2006. Its first mission is to fly over Pluto to learn more about this distant dwarf planet. Its second mission is to study objects in the Kuiper belt. After launch, new horizons flew over Jupiter, then entered dormancy mode and reached Pluto in 2015. The probe then stayed near Pluto until the end of 2016, when it began its long journey to the Kuiper belt.

Scientists discovered ammonia by studying data from new horizons about Pluto. The existence of ammonia and other solutes can reduce the freezing point of water and increase the possibility of water in liquid state. As a result, the discovery of ammonia increases Pluto’s chances of having a liquid lake or ocean. Although Pluto’s surface temperature is as low as minus 230 degrees Celsius, due to the internal heat generated by the radioactive decay of its core, Pluto may contain groundwater.

In addition to ammonia, the researchers also speculate that Pluto has conditions conducive to the formation and evolution of life, such as oceans, DNA, RNA and amino acids. If so, Pluto also has the possibility of life. Scientists explore the solar system liquid water resources, the main purpose is to find the possible existence of alien life.

Scientists have always believed that in the vast universe, only the earth can have life. Although scientists believe that life in the universe may have different requirements for the environment and the formation of life will be different, it is a right shortcut to search for extraterrestrial life according to the survival needs of life on the earth. The birth of life on earth is inseparable from liquid water, so the possibility of life on an alien planet with liquid water is naturally greater.

There are so many planets in the solar system that there may be a large amount of liquid water, which indicates that the solar system may be a galaxy where life is ubiquitous. However, the current technology of human beings is still relatively backward, and we can’t go deep into the surface of these planets to explore. I believe that with the continuous development of science and technology, when one day we can go deep under the surface of Ganymede, Europa, Callisto, Mars and Titan, we may find traces of life all over the solar system and even the universe. We are looking forward to this day.
