There are eight planets in the solar system, among which Venus, earth and Mars are rocky planets, while Jupiter and Saturn are gas giant planets. Rocky planets are mainly composed of solid rock structures. Some have atmospheres, while others do not.
The earth is a living planet with a very thick atmosphere, which can effectively protect the earth’s ecological environment, which is also the characteristic of living planet. Without the protection of a thick atmosphere, life could not have been born on the earth, there would not have been a huge area of liquid water resources, let alone the birth of human beings.
There is a big difference between gas giant planets and rocky planets. The most obvious difference is that gas giant planets are dominated by atmosphere. Although they also have a solid metal core, it is really insignificant compared with the thick atmosphere. The largest planet in the solar system is Jupiter, which is a huge gaseous planet.
Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, and the fifth planet from the inside out. Its mass is one thousandth that of the sun, 2.5 times that of the other seven planets in the solar system. Jupiter is a gas giant planet. The main component of the atmosphere is hydrogen, accounting for 75% of its total mass, followed by helium, accounting for 25% of its total mass, which is very similar to the composition of the sun. Therefore, gas giant planets are also known as the failed stars.
The reason why the earth has wind, rain and lightning is mainly brought by the atmosphere. For example, the earth often has storms, and its cause is the movement of the atmosphere. If the earth is like this, then Jupiter, which is dominated by the atmosphere, naturally has all kinds of super storms. Jupiter’s storms are very powerful. Of course, the mysteries of Jupiter’s atmosphere are beyond our knowledge.
I believe many astronomy enthusiasts should know that the most beautiful scenery of Jupiter is the spectacular scene formed by various storms above, among which a particularly huge red spot is the most concerned by scientists. How the erythema was formed is still a mystery. In the age of science and technology, when we had astronomical telescopes, we found this very conspicuous red spot on Jupiter, which is three times the size of the earth.
To explore Jupiter and learn more about Jupiter’s great red spot, scientists launched the Juno Jupiter probe in 2011. After a long flight, Juno spacecraft finally reached the orbit of Jupiter, and also saw the magnificent red spot above Jupiter from a close distance. When we observe this red spot through an astronomical telescope, we can only see that it is relatively large.
But through the close observation of the spaceship, you will be shocked by its magnificence. On April 1, 2018, NASA’s Juno spacecraft took the original picture of the great red spot. By analyzing the data obtained, scientists drew amazing images. Only close observation, we can truly understand the scale of Jupiter’s great red spot, mysterious anomaly.
Don’t underestimate this big red spot. It’s not only huge, but also powerful. If there is material or a small storm, it will be torn to pieces. The great red spot rotates counter clockwise and is an anticyclone with wind speed up to 500 km / h. It has been nearly 300 years since the discovery of Jupiter’s great red spot.
The first discovery of the great red spot is more huge, but today, 300 years later, some changes are quietly taking place in Jupiter’s great red spot. The most obvious is that its volume is shrinking. Scientists have observed that Jupiter’s great red spot is shrinking. At the same time, its roundness and height are constantly proposed, and its color is also changing significantly with time.
It is still unknown what causes these changes in Jupiter’s great red spot. What is its future? It’s still an unknown number. Jupiter’s cloud rings are colorful. The dark ones are called “belts” and the light ones are called “regions”, parallel to Jupiter’s equator. Scientists are not sure what causes the color difference between the band and the zone. However, their chemical composition, temperature and atmospheric light transmittance may all be influencing factors.
As time goes on, the longitude of erythema major is changing greatly. Recent evidence shows that its westward longitudinal velocity is increasing. Like the great red spot, the latitude of the cloud belt has hardly changed over time. Researchers have not yet fully understood the structure of the cloud belt, but there is evidence that the light cloud area is the area of material rising, and the dark cloud area is the area of material sinking.
The great red spot is a Jupiter storm in simple terms, but in deep terms, it may be the result of many factors. And its life span is extremely long. Human beings have observed it for 300 years. It may have existed before human beings had astronomical telescopes, and it may be longer than the history of human civilization. It’s really a storm of longevity.
While Jupiter’s great red spot is shrinking, its color is also changing obviously. Does this mean that this longevity storm is coming to an end? Scientists don’t understand that either. Scientists can only get more data about the great red spot through the detector, so as to find out the cause of this change, that is, to understand the mystery of the entire atmosphere of Jupiter.
The shrinking of Jupiter’s great red spot doesn’t mean that it will disappear. It may just change to fine. When it shrinks to a certain extent, it may become more powerful and become a stronger storm. And scientists through the study of “Juno” returned data about Jupiter’s great red spot, found that there may be liquid water inside the great red spot.
In scientists’ cognition, Jupiter is a gaseous planet full of hydrogen and helium, and the possibility of forming liquid water is very small. However, this discovery once again overturns people’s cognition. Scientists say that if there is liquid water inside the great red spot, there should be oxygen on the surface of Jupiter. We need to further explore whether there will be life here.
Although Jupiter is a gas giant planet, it does not mean that Jupiter’s atmosphere is composed of gas structure. Scientists believe that Jupiter’s atmosphere is mainly composed of three layers. The outermost layer is the gas atmosphere. The great red spot and various storms occur in this layer. Below the gaseous atmosphere is the structure of the liquid atmosphere, where, due to the increasing atmospheric pressure, the gaseous hydrogen has been liquefied to form a liquid layer.
Further down, the pressure is greater. At this time, the liquid hydrogen is compressed again to form solid hydrogen. Therefore, if an object ignores the pressure of Jupiter’s atmosphere and can continue to sink, it will not reach the metal core of Jupiter, but will eventually fall on the solid hydrogen. Maybe in the interior of Jupiter, the structure of solid hydrogen is equivalent to the surface of Jupiter.
Of course, we know very little about Jupiter now. Whether it’s the great red spot or other storm scenes, we can only see the surface, and the detector can only detect in the orbit of Jupiter, and can’t go deep into the atmosphere at all. If you want to really enter the interior of Jupiter’s atmosphere, you need a spacecraft that can withstand its super pressure and super storms. This kind of spaceship can’t do with the current technology of human beings.
With the continuous progress of human science and technology, it is not a matter to explore the interior of Jupiter in the future. At that time, maybe we will find that there may be holes inside Jupiter. There was a science fiction film describing that human built a living city inside Jupiter. If there are holes inside Jupiter, it may also become a living planet for human in the future.
