Jupiter is likely to have the moon as a surroundings under its surface

If there is a competition for the most interesting moon in our solar system, Callisto will be a competitor. The second largest moon on Jupiter has more pits on its surface more than any other planetary body in the solar system, and it has a lot of ice on its surface as well.

For decades. The researchers went to rest under it Callisto Pockmark It is the liquid salty water perimeter that extends over the entire moon. After taking a closer look at the data 30 years ago, researchers now have stronger evidence of the existence of such an ocean.

Corey J According to Kokran, the team was working on it Various projectwith Neptune Triton satellite wiped To find out if it has a circumference below the surface of the earth.

This is a challenge, due to the intense ionosphere of ionosphere, which is the last layer of atmosphere before the start of space. Since Callisto also has an intense ionus, the team decided to test their methods of 30 -year -olds taken by NASA Galileo Mission. This mission was launched in 1989 and wiped Jupiter and its moons between 1995 and 2003.

“Our conclusions were enabled by analyzing the measurements obtained from Callisto fly, which was usually neglected in society due to the existence of an increasing” noise “attributed to the plasma environment.”

“We have been able to take advantage of the pre -developed plasma simulations to remove this mysterious plasma noise from the measurement so that the signal from the ocean can be analyzed independently,” said Kokran.

In short, it was difficult to explain Galileo’s readings because of the powerful Uonosvir in Callisto. Once Cochrane and his team cleaned the readings, they managed to think about data, and he strongly indicates the presence of an ocean under the outer appearance of the rock moon.

Ionosphere looks like an ocean

It takes a long time to demonstrate the presence of a circumference under the surface of the earth on Callisto because a strong ionosphere simulates the readings that you will get if there is such an ocean.

“The basic physical law of nature (magnetic induction law in Faradai) indicates that if you move a magnet in relation to any connected substance, such as a copper wire, it will create an electric current within this wire that coincided with the movement of magnets,” explained Cokrin. “This current will then lead to the creation of a secondary magnetic field (due to the movement of electrons in the wire), which is called the inductive magnetic field, which displays the properties of the conductive material.”

Cocran said this works with planetary bodies as well. Satellites or planets with adequate heat can contain the vicinity of liquid salt water below the surface. These oceans are electrically connected thanks to salt in water. Thus, scientists can use magnetic measures to measure a magnetic field that “maintains ocean properties”. In other words, oceans can be found based on the magnetic fields they generate.

Since satellites such as Jupiter in Callisto and Neptune’s Triton have very strong ionosphere, magnetic readings are so noisy that researchers are facing a problem in knowing whether what they are looking for is an ocean or just random noise of additional energy in ionosphere. For this reason, the researchers were stuck in the potential underground Callisto vicinity for decades.

The following steps

Science will not have to wait another 30 years to find evidence. NASA’s mission in Europe was sailed Last year, it should reach Jupiter and its moons in 2030, while the European Space Agency Juice You should arrive in 2031. Both tasks will surely provide more Callisto search data.

Regarding the information they will collect, Cochne told us that it is not necessarily different data. Instead, it’s more data.

“Proof of the presence of Callisto from new measurements is simply due to the fact that there are more measurements available for analysis,” said Cokran. “For every fly that occurs for each of these missions, a very small snapshot is captured at the time of the magnetic field environment by the magnetic scale.”

Kokran said that the data of the coffee and juice materials in Europe will help “fill holes” from the Galileo mission, and we hope that the researchers will eventually allow whether there is an ocean in Calisto. Additional data will also help researchers estimate the thick ocean layer in Callisto, as well as the thickness of the ice shell over it.

Can there be life on Callisto?

NASA and the European Space Agency will not send tasks to Jupiter without good reasons to do so. One this: The hidden Europe waters are the front filter For life outside the planet.

“It is possible to support the ocean in Europe because we know that it hosts the main components of its support, those that are water and basic chemical elements and energy (such as the heat source from the inside) over a long time enough time to develop,” said Kokran. “EUROPA Clipper is in fact a housing task (it should not be confused with the discovery of life) that will provide the data required to better help us answer this question. Until that time, it is difficult to comment on whether it is possible.”

But there is a growing case of life on Callisto. She has Amazing amount of oxygenAnd no one can know where most of them came from. Poison it with an increasing possibility of under the surface of the Earth, and although it is still far from the sure thing, this is enough evidence to justify a closer look at the Jupiter Moon when the missions arrive in 2030 and 2031.
