What is the Great Red Spot on Jupiter? How Jupiter s Great Red Spot is formed

The Great Red Spot in Jupiter's atmosphere is a vigorous anticlockwise downdraft that contains a large amount of red phosphide and is dark brown. The location of this large red spot is not fixed, but is constantly moving. Jupiter's Great Red Spot is roughly located at 23° south latitude, and its north-south width is often maintained at 14,000 km, with its length varying from east to west at different times, reaching about 40,000 km at its longest and generally at 20,000 to 30,000 km.

In the center of the Great Red Spot there is a small particle, which is the nucleus of the Great Red Spot, which is about a few hundred kilometers in size. This nucleus remains immobile in the surrounding anticlockwise vortex motion. The Great Red Spot has a long lifespan and can last for hundreds of years or more.

The Great Red Spot is the form of Jupiter's atmosphere, like clouds in the Earth's sky. Cassini used this Great Red Spot to accurately measure Jupiter's rotation period, and people have also observed that the color of the Great Red Spot is sometimes very strong, sometimes light, and people can only faintly see its outline. The Great Red Spot also has a drifting motion in the latitudinal direction, so the Great Red Spot is not a solid substance.

Jupiter's Great Red Spot is huge in diameter, can hold 3 Earths, its shape can change somewhat, the Great Red Spot can last for hundreds of years, there must be another mechanism to replenish energy, so that this supercyclone can continue to maintain, otherwise according to our current hydrodynamic theory, the Great Red Spot would have gradually lost energy and disappeared centuries ago.

The vertical flow in Jupiter's atmosphere can attract hot gases to inject energy into the system from the top of the Great Red Spot, and cold gas enters the center of the storm from the middle and bottom.

The Great Red Spot on Jupiter is a huge storm that gathers cold air to form a dense area of matter, which reflects the red light, thus forming the Great Red Spot.

For example, almost everyone knows what the Earth looks like, because the Earth's surface is mostly covered by oceans, some people think it looks like a blue marble ball Many people can recognize Mars because of its iconic red color, similarly, Saturn has a unique Saturn rings that also make it easy for people to remember, and those who know what Jupiter looks like are also usually recognized by its Great Red Spot Why there is a Great Red Spot on Jupiter, which is the sunburn of the sun, what aliens spit out to form it, Could it be a sea of cranberry juice, these far-fetched ideas are far from the truth, and Jupiter's Great Red Spot is actually a big storm.

Gas vortex. Scientists believe that the red color of this red spot is due to the fact that the deep red material is carried up by the vortex and takes on a maroish red color when exposed to the sun's ultraviolet rays.

Jupiter. It is a gas planet, the Great Red Spot.

The root cause of Jupiter's poor rotation – not only does it form a great red spot, it also forms several cloud bands and several "small red spots" and "great white spots".

Jupiter's Great Red Spot is located at 23 degrees south latitude of Jupiter. The Great Red Spot is a giant vortex of gas. The diameter of the Great Red Spot is larger than the diameter of the Earth, about twice the diameter of the Earth.

To the great surprise of all astronomers, Jupiter's Great Red Spot can appear all the way in the same location and can rotate counterclockwise at a steady rotation speed for one week for six Earth days. In addition, it has been around for more than 300 years since the discovery of the Great Red Spot.

Jupiter rotates clockwise from west to east. Jupiter's rotation period is 9 hours, 55 minutes, and 30 seconds. Jupiter's rotation period is determined based on the Great Red Spot and Jupiter's rotation period. Jupiter's equatorial clouds move faster, while Jupiter's polar clouds move more slowly.

Jupiter's Great Red Spot is reddish-brown because Jupiter's lower atmosphere contains a lot of sulfur and ammonia particles. Because the mass of sulfur and ammonia particles is higher than that of water vapor.

Composition of the cloud is large.

So covered by clouds. When Jupiter's atmosphere forms a gas spiral, the gas spiral absorbs sulfur and ammonia particles under the clouds, giving Jupiter's Great Red Spot a reddish-brown color.

The size of the large red spot is decreasing. Mathematical models.

It is estimated that storms are stable and may become a permanent feature of the planet. However, since it was discovered, there has been a noticeable decrease in its size. Initial observations in the late 19th century showed that it had a circumference of nearly 41,000 km.

To 1979 Traveler.

At the time of observation, the storm was 23,000 km long and nearly 13,000 km wide. Hubble's observations in 1995 showed that its size had decreased again to 20,950 km, and in 2009 it had reached 17,910 km. By 2015, about 16,500 km of storms had been measured, and the rate was decreasing at a rate of 930 km per year.

Each planet has its characteristics, for example, the surface of the Earth is covered by more than 70% of the oceans, we think it is blue, while Mars has the signature red, Saturn has Saturn's rings, and what about Jupiter?

Q: What is the Great Red Spot on Jupiter?

Answer: Jupiter's Great Red Spot is actually a big storm.

Eye of Jupiter: Great Red Spot.

Earth's storms are insignificant compared to Jupiter's Great Red Spot, and the largest and most powerful storm ever recorded on Earth is a large hurricane that stretches for kilometers and reaches kilometers per hour. The Great Red Spot storm has a range twice that of the Earth, with maximum wind speeds of kilometers per hour.

The howling storm on Jupiter has been around for at least 150 years, and possibly 400 years or more. In contrast, Hurricane John, the largest storm on Earth in 1994, lasted only 31 days.

The Great Red Spot is a region of constant high pressure in Jupiter's atmosphere, which produces an anticyclonic storm, the largest storm in the solar system, located 22 degrees south of Jupiter's equator. It has been observed continuously since 1830, and early observations from 1665-1713 are thought to be the same Great Red Spot storm, and if so, the Great Red Spot has been around for at least 350 years.

However, despite its long lifespan, the Great Red Spot has been steadily shrinking. End of the XIX century. The Great Red Spot is about four times the size of Earth, and by 1979, when Voyager 2 flew over Jupiter, the storm had shrunk to twice the size of Earth.

Today, the Great Red Spot is only twice the size of the Earth, and some scientists believe it is still shrinking, and perhaps a younger generation will witness its disappearance.

With the help of data from NASA's Juno spacecraft, scientists continue to study Jupiter and the Great Red Spot today. Some scientists are still trying to figure out why the storm is red, and the most popular theory today is that cosmic rays, as well as the sun's ultraviolet rays, reacted with hydrogen sulfide ammonia in Jupiter's atmosphere to give the Great Red Spot its red color.

Introduction to Jupiter

Jupiter has been known to astronomers since ancient times. People named it the Roman god Juppeter. As the fifth-closest planet to the Sun in the Solar System, Jupiter is also the largest planet in the system.

This giant planet is only one-thousandth the mass of the Sun, but it has a mass of several times the mass of the other planets in the solar system combined. Jupiter and Saturn are both gas planets, and the other two giant planets, Uranus and Neptune, are ice giants.

Jupiter's apparent magnitude is achievable, and its reflected light is so bright that it can cast shadows on objects, making Jupiter the third brightest natural object in the night sky on average after Venus and the Moon.

What is the Great Red Spot on Jupiter?

The Great Red Spot is a massive anticyclonic storm in Jupiter's Southern Hemisphere, located at 22°S latitude and lasting for at least 340 years. It is about 20,000 kilometers long and 10,000 kilometers wide, and is four times the size of the Earth. Use a telescope to look at Jupiter on Earth, which can be seen when the Great Red Spot is facing Earth.

First observed by Cassini or Hook in 1665, the Great Red Ban was more intensely coloured, but has now faded. Some people believe that this peculiar Great Red Spot is the eye of a super typhoon, while others believe that it is caused by the agitation of air currents from two different directions of Jupiter, but the true cause is still a mystery. On February 25, 1979, the Voyager 1 spacecraft visited Jupiter and photographed the Great Red Spot at a distance of 92 million kilometers from the surface.

Jupiter's atmosphere is composed of 81% hydrogen and 18% helium by number of molecules, 75% by mass and 24% respectively. There are only about 1% or so of other gases, including methane, water vapor, ammonia, etc. This is similar to the composition of the primordial solar nebula, the predecessor of the solar system.

Saturn, which is also a gas planet, is of a similar composition, but Uranus and Neptune have far less hydrogen and helium. Due to Jupiter's rapid rotation, Jupiter's atmosphere appears very "restless". Jupiter's atmosphere is actually a complex and changeable weather system, Jupiter's clouds'The pattern changes from moment to moment.

We can see large and small storms on the surface of Jupiter, the most famous of which is the "Great Red Spot". It is an ancient storm that rotates in a clockwise direction, it was discovered by humans more than 300 years ago, and is generally believed to have been discovered by Cassini or Hook in the 17th century, that is, this huge storm has been in Jupiter's atmosphere for hundreds of years. The Great Red Spot is the size of three Earths, and its outer cloud system moves once every four to six days, and the storm cloud system moves slightly slower and in an uncertain direction.

Due to the violent movement of Jupiter's atmosphere, there are similar high-altitude lightning on Jupiter as on Earth.

Analysis: The Great Red Spot is a feature of Jupiter. It's big enough to encircle three Earths.

The Great Red Spot was first described in 1660 and has been observed for more than 300 years. It has changed color and shape, but it has never completely disappeared. It is now widely believed to be a persistent storm in Jupiter's upper atmosphere.

Jupiter and other gaseous planets have high-velocity hurricanes on their surfaces and are confined to a narrow range of latitudes, with winds blowing in the opposite direction even near latitudes. Slight changes in the chemical composition and temperature of these bands create colorful surface bands that govern the appearance of the planets. The shiny surface bands are called zones, and the dark ones are called belts.

These bands on Jupiter have been known for a long time, but the whirlpools in the band's boundary zone were first discovered by the Voyager spacecraft. Data sent back by the Galileo spacecraft indicated that surface winds were much faster than expected (greater than 400 mph) and extended to as deep as the roots could observe, extending thousands of kilometers inward. Jupiter's atmosphere has also been found to be quite disordered, suggesting that the heat inside causes hurricanes to move most of the time, unlike Earth, which only gets its heat from the Sun.

The colorful clouds on Jupiter's surface may be caused by subtle differences in the chemical composition of the atmosphere and their effects, possibly mixed with a mixture of sulfur to create a colorful visual effect, but the details of this are unknown.

The change in color depends on the height of the clouds: blue at the lowest, followed by brown and white, and red at the highest. We can see the clouds below through the holes in the clouds above.

The Great Red Spot on Jupiter's surface was known to Earth observations as early as 300 years ago (a discovery often attributed to Cassini, or Robert Hooke in the 17th century). The Great Red Spot is a 25,000 km long and 12,000 km long ellipse that can accommodate two Earths. Other, smaller spots have also been seen for decades.

Infrared observations, combined with the derivation of its rotation trend, show that the Great Red Spot is a high-pressure area, where the top of the cloud layer is particularly high and cold compared to the surrounding area. A similar situation is seen on Saturn and Neptune. It is not clear why such structures can last for that long.
