According to scientific research, it may exist, in November 2009, Richard Greenberg, a scientist at the University of Arizona in the United States, and others found that Europa may have a life similar to that of fish Many scientists believe that Europa has no land on the surface, and there is an ocean covering the whole world under the thick ice, with a depth of about 160 kilometers.
Greenberg's latest research shows that Europa's ocean is absorbing a lot of oxygen, much more than previous simulations**.
Scientists believe that this oxygen is enough to support the existence of multiple life forms, and theoretically there should be at least 3 million tons of fish-like organisms in Europa's ocean. Greenberg explained, "Although it is not yet possible to say that life is definitely there, we at least know that the physical environment there supports the existence of life." ”

Life on Europa, one of Jupiter's moons, is more likely than ever. The researchers point out that the ice on Europa is no more than a few kilometers thick, meaning that the ice is thin enough to break it under tidal pressure, so life can thrive in the ocean beneath the ice. Astrobiologists worry that if the ice is too thick, all that exists beneath the ice are life forms that derive their chemical energy from hydrothermal sources.
A team of scientists led by Dr. Richard Greenberg at the University of Arizona's Planetary and Satellite Laboratory in the United States carefully studied the data sent back from the Galileo probe and collected evidence that Europa's ice was no more than 10 kilometers thick. After studying 10% of Europa's surface on high-resolution** captured by Galileo, scientists determined that about half of the surface was made up of "tectonic geology" terrain with long straight mountains and breaklines, while the other half was covered with ice that piled up on top of each other in a haphazard manner as if it had been moved in the surrounding liquid medium. The researchers believe that the combination of these two types of terrain could illustrate that break lines or areas of melting and ice in the ice periodically bring ice beneath the ocean to the surface.
Another feature of the ice allows scientists to analyze the breakline sections, which show the cyclical nature of Europa's geological structure. The researchers accurately determined some of the segments, and in addition, the Greenberg team found intersections, although they were not as pronounced as they were on Earth. There is very little solid matter on Europa, so there are no mountains on Europa.
Calculations by a team of scientists show that the daily tides cause the warm water to rise upwards to the point where it remains relatively balanced. This has the potential to give any living thing access to sunlight and organic matter from small meteorites, thus creating areas where life can be born directly. Researchers speculate about which organisms are likely to do this:
It attaches to the rock wall at the fracture in order to get sunlight, and only jellyfish-like creatures can rise or fall with the current.
Most of Europa's surface fractures can last for thousands of years, but as it revolves around Jupiter, the points of tidal pressure in the Earth's crust move, and some break freezes ice, at which point what scientists speculate is to hibernate or migrate somewhere else.

There are a total of 79 moons of Jupiter. Among them Ganymede. 1. Ganymede.
2. Ganymede. 3. Europa was discovered by the Italian astronomer Galileo Galilei in 161 with a homemade telescope, and these four moons were later called Galileo moons.
On July 17, 218, American researchers said that they had discovered 12 new moons of Jupiter, bringing the total number of known Ganymedes to 79. One of the newly discovered satellites is at risk of colliding head-on with the other satellites.

The Romans cleverly named Jupiter, the king of the gods. In addition to being the largest planet in the solar system – with a mass twice the mass of all other planets combined – Jupiter is also the planet with the most moons in the solar system. So far, 79 natural satellites have been discovered around this giant gas planet, and there are many more that may exist.
-
Jupiter has many moons, with six large moons orbiting Jupiter.
-
Jupiter has 16 moons, which can be said to be a big family, in the solar system, second only to Saturn's 23, like a small solar system!

Now Jupiter, there are still many kinds, moons, and, Jupiter, I think this still needs to be shared by all of us, and this is also a very much anticipated topic.

Jupiter has discovered 79 moons.
Ilymede. 1. Ganymede.
2. Ganymede. 3. Ganymede was discovered by Galileo with a telescope in 1610 and is called the Galilean Moon. Barnard discovered Europto in 1892, and other moons were discovered by photographic methods after 1904.
The Voyager spacecraft discovered Europa XIV in 1979, followed by Europa XV and Callisto XVI in 1980. With the exception of the four Galileo moons, the rest of the moons have a radius of several thousand meters to 20 kilometers of large rocks.
With a radius of 2,631 kilometers, Ganymede is the largest of the moons and larger in diameter than Mercury. Europa may have a liquid ocean. Jupiter's four Galilean moons and the orbits of Europa are almost on Jupiter's equatorial plane.

Jupiter, known since ancient times, is easy to see at night with the naked eye and occasionally during the day when the Sun is low. In Babylon, this celestial body represents their god Marduk. They used Jupiter's orbit to orbit the ecliptic for about 12 years to define the star house of their zodiac.
The Romans mythologically named Jupiter (Latin: iuppiter, iūpiter, also known as jova), the main god in Roman mythology, whose name comes from the Proto-Indo-European accusative compound *dyēu-p ter (nominative case: *dyēus-p tēr, meaning "o god father" or "o day god father").
Comparatively, Jupiter corresponds to the Greek mythology of Zeus (also known as Dias(δ and the names of the planets in which the names are still preserved in modern Greek. In English, Thursday (Thursday) is derived from "Thor's Day" (Thor).'s day), which is out of Germanic mythology. Compared to Roman mythology, it is Jupiter.
Jovis of Roman Thursday also re-named Thursday.

No. Jupiter is much farther from the Sun than Earth, it receives much less solar radiation, and the surface temperature is naturally much lower. According to the calculations, the surface temperature of Jupiter should be minus 168 degrees Celsius.
However, the observed temperature on the ground was minus 139 degrees Celsius, which was nearly 30 degrees Celsius different from the calculated value, which could not have been caused by an error in any way.
Having a probe take measurements near Jupiter should be more accurate. When Pioneer 11 flew by Jupiter in December 1974, the measured surface temperature of Jupiter was minus 148 degrees Celsius, which is still much higher than the theoretical value of the Wild Wanderer, indicating that Jupiter has its own internal heat source.
Infrared measurements of Jupiter reflect a similar picture. If there is no heat source inside Jupiter, the amount of heat it absorbs and the amount it spends should be in balance, as is the case with planets like Earth and Mercury. Jupiter is not, it is a branch greater than in, about a large number, this overrun energy from the **?
Obviously, it can only be subsidized by its own internal heat source.
Jupiter is a celestial body with hydrogen as its main component, which is very different from our Earth and similar to the Sun. The atmospheres of both the planetary bodies Jupiter and the Sun contain about 90 hydrogen and 10 helium, as well as very small amounts of other gases. With regard to Jupiter's internal structure, the model now established suggests that its surface is not solid, and that the entire planet is in a fluid state.
The central part of Jupiter is probably a solid core, mainly composed of iron and silicon, where the temperature of the branch chain can be at least 30,000 degrees. On the outside of the grinding nucleus are two layers of hydrogen, first one in the state of liquid metallic hydrogen, and then one layer of hydrogen in the state of liquid molecular hydrogen; Together, these two layers are called the Jupiter mantle. Further up, hydrogen becomes the main component of the atmosphere in its gaseous state.
Scientists have found that Jupiter emits twice as much heat as it receives from the Sun, which means that Jupiter itself heats up, and its brightness is increasing year by year. At the same time, Jupiter is very big and constantly has to get the material thrown out by the solar system, and some people predict that in 3 billion years, Jupiter will have a mass similar to that of the Sun, and then it will become a luminous and hot star, that is, it will become the second sun.
