Chapter 1823 Jupiter’s Great Red Spot

Jupiter's magnetosphere has a large range and complex structure, and the huge space between 1.4 million and 7 million kilometers away from Jupiter is Jupiter's magnetosphere.

The earth's magnetosphere is only within the range of 50,000 to 70,000 kilometers from the center of the earth. Jupiter's five large satellites are all shielded by Jupiter's magnetosphere from the solar wind.

There is a radiation belt around the Earth called the Van Allen belts, and there are such radiation belts around Jupiter. Some scientists have also found that there is a 30,000-kilometer-long northern lights on the side of Jupiter facing away from the sun. From this point of view, Jupiter's magnetotail has been stretched to at least 60 million kilometers away.

The distribution of Jupiter's magnetosphere is more than 100 times larger than that of the Earth's magnetosphere, and it is the largest magnetosphere in the solar system. Due to the effect of the solar wind and the magnetosphere, Jupiter also has auroras in the polar regions like the earth, and the intensity is about 100 times that of the earth.

Jupiter's Great Red Spot is located at 23° south latitude, 20,000 kilometers long and 11,000 kilometers wide. The probe found that the Great Red Spot is a violent updraft that is dark brown in color. This colorful cyclone turns in a counterclockwise direction.

There is a small particle in the central part of the Great Red Spot, which is the core of the Great Red Spot, and its size is about several hundred kilometers. This nucleus remains motionless in a counterclockwise swirling motion around it. The Great Red Spot is very long-lived, lasting hundreds of years or more. As early as 1665, the Italian astronomer Cassini discovered it. The vivid red color of the Great Red Spot is impressive, and the color seems to come from red phosphorus.

The spin of the egg-shaped object is counterclockwise, with a period of about six days. The dimensions of the Great Red Spot are 24,000 to 40,000 km x 12,000 to 14,000 km. Its diameter is large enough to accommodate 2 to 3 Earths. The storm's maximum height was about 8 kilometers above the surrounding clouds.

Storms typically occur in the turbulent atmospheres of giant planets. Jupiter also has white and brown oval-shaped storms, but the smaller ones are usually not named. White goose eggs tend to contain the upper, relatively cool clouds of the atmosphere. Brown ovals are warmer and lie in normal cloud cover. Such storms can last from just a few hours to centuries.

In 1953, the Miller-Urey experiment demonstrated that the combination of lightning and compounds present in the primordial Earth's atmosphere could form organic matter (including amino acids), which could serve as the building blocks of life. The simulated atmosphere consists of water, methane, ammonia, and molecular hydrogen; all of these substances are found in the atmosphere of Jupiter today.

Jupiter's atmosphere has strong vertical air currents that carry these compounds into lower regions. But the higher temperatures in Jupiter's interior would break down these chemicals, preventing the formation of Earth-like life.

On Jupiter, because there is only a small amount of water in Jupiter's atmosphere, and any solid surface is deep in the extremely pressurized region, it is considered impossible for any Earth-like life to exist.

In 1976, prior to the Voyager mission, it was postulated that life based on ammonia and water might have evolved in the upper layers of Jupiter's atmosphere. This hypothesis is based on the Earth's oceanic environment, with simple photosynthetic plankton in the top layer, fish in the lower layer can feed these organisms, and carnivorous marine life can hunt these fish. On some of Jupiter's moons, there may be oceans under the surface, leading to speculation that these moons are more likely to harbor life.

Zhao Zhongyao looked at Feifei now and told him some knowledge about Jupiter.

After Feifei heard this, she had a deeper understanding of this Jupiter. But among some astronomical phenomena about Mars, there is one astronomical phenomenon that is very famous. It is the eye of a huge storm on the surface of Jupiter - the Great Red Spot.

When it comes to Jupiter, people with a little knowledge of astronomy will think of the Great Red Spot. After all, as long as we observe Jupiter with astronomical telescopes, we will definitely be able to see the Great Red Spot on Jupiter.

Thinking of this, Feifei looked at Zhao Zhongyao again and said, 'Dad, can you tell us more about Jupiter's Great Red Spot. I also wanted to learn more about Jupiter's Great Red Spot. '

After hearing Feifei's words, Zhao Zhongyao said, 'Okay, since this is the case, let me tell you some more about Jupiter's Great Red Spot! '

After finishing speaking, Zhao Zhongyao told the family some knowledge about Jupiter's Great Red Spot.

The Great Red Spot of Jupiter is a characteristic sign on the surface of Jupiter. It is the largest storm cyclone on Jupiter. It is about 25,000 kilometers long and spans 12,000 kilometers up and down. It rotates counterclockwise every 6 Earth days and often rolls up to 8 kilometers. cloud tower. The Great Red Spot has existed for at least 200 to 350 years, since astronomers first observed the storm in the 17th century. It has changed color and shape, but never completely disappeared.

The Great Red Spot in Jupiter's atmosphere is a group of violent downdrafts moving counterclockwise. The material of this airflow contains a large amount of red phosphorus, so it is dark brown.

The position of the Great Red Spot is not fixed, but is constantly moving. The Great Red Spot of Jupiter is roughly located at 23° south latitude. Its north-south width is often maintained at 14,000 kilometers, and its length in the east-west direction varies in different periods. km.

There is a small particle in the central part of the Great Red Spot, which is the core of the Great Red Spot, and its size is about several hundred kilometers. This nucleus remains motionless in a counterclockwise swirling motion around it. The Great Red Spot is very long-lived, lasting hundreds of years or more.

According to the observation results, scientists found that the reddest area in Jupiter's Great Red Spot confirmed the theory that there is a hot core inside the cold storm system; and the dark lines on the edge of the storm in the observation image show that the gas released by the storm eruption is moving toward

The interior of the planet spreads.

Italian astronomer Cassini pointed out that the Great Red Spot is the shape of Jupiter's atmosphere, just like the clouds in the sky of the earth. Cassini used the Great Red Spot to accurately measure the period of Jupiter's rotation. People also found in the observation that the color of the Great Red Spot is sometimes very strong, sometimes light, so light that people can only vaguely see its outline. The Great Red Spot also drifts in the latitude direction, so the Great Red Spot is not a solid matter.

Jupiter is the planet with the fastest rotation speed in the solar system, which makes the clouds in the atmosphere stretched into long strips, forming a total of 17 cloud belts. The brighter parts of cloud bands are called "bands" and the darker parts are called "ribbons". From the photos taken by the probe, the clouds in the atmosphere flipped violently, and there was a prominent Great Red Spot in the tumbling clouds. The Great Red Spot rides the updraft in the atmosphere and rotates counterclockwise about 6 Earth days.
