The Great Red Jupiter Zone: A 300-year-old cyclone continues but declines



The Great Red Spot, a storm that is taller than the Earth and is so strong enough to destroy smaller storms, is one of the most distinctive features of Jupiter and the entire solar system. A storm against the needle, an anticyclone, has a high speed of 300 kilometers per hour. This important feature, seen since 1830, and probably since the 1660s, has long been a source of fascination and scientific research.

Not much is known about the Great Red Spot, exactly when and how it was created, what is its striking red color and why it has survived the other storms seen in Jupiter's atmosphere. However, astronomers believe that Jupiter's equator is located at latitude 22 degrees south of the Jupiter-bound strip band.

As a planetary astronomer who looks at atmospheric atmospheres, I usually do not investigate massive storms. But I still want to know the features that are visible in the atmosphere of other solar system bodies, including Jupiter. It helps you to understand how it works and how it works.

Unlike Jupiter, the earth's frosts with solid surfaces lose energy due to earth mass. Without this feature, Jupiter storms last longer. However, the Great Red Spot lives long, as well as Jupiter. The researchers do not understand why, but we know that the Jupiter storms that are located in the same direction of rotation are longer.

These colorful bands, called belts (dark bands) and zones (clear bands), are parallel to the Jupiter equator. The researchers are not sure what band and field color they cause, but all of the differences in chemical composition, temperature and transparency of light have been clarified. These bands are also a counter-rotation, that is, moving in the opposite direction with their neighbors. The boundaries between bands and areas are called jets of zones marked by strong winds.

The Great Red Spot is a northeastern bird in the north and south is a western aircraft bordering on the south, limiting the storm to a constant latitude. However, the Great Red Spot has undergone significant changes over time, and recent evidence suggests that its long-range movement in the West is increasing.

Like the Great Red Spot, the groups have undergone little change in latitude during their observation time. The researchers do not fully understand the common structure, but it seems that color-proof sites are regions with rising materials, and dark girders are materials that penetrate into the atmosphere.

On the ground, there is a very well-defined border between atmospheric and planetary surface, largely covering liquids. However, there is no known ocean in the clouds of Jupiter. As the researchers know, in the atmosphere, the internal hydrogen of the liquid is penetrated. Jupiter's core could be strong, but it is surely buried deep under liquid metal hydrogen, which acts as a conductor of hydrogen.

What else can we know about the Red Spot, which is changing dramatically? Its size, shape and color. It has been shown that the historical data of the Red Spot and the data obtained lately has become more rounded and rounded, and its color has also changed over time. What are these changes, and what do they mean for the future of the Red Spot? The researchers are not sure.

However, NASA's Juno spacecraft, orbiting around Jupiter, is collecting more data about the international band and the red dot. These new details will inform Jupiter's many atmospheric features.
