Jupiter’s Moon Callisto Probably Has an Ocean Under Its Surface


If there was a competition for the most interesting month in our solar system, Callisto would be a bidder. The second largest bear of Jupiter has more effective craters than any other planetary body in the solar system and has tons of ice on its surface.

For decades. The researchers meant to rest in the bottom Callisto’s stick surface A liquid sealed ocean covering the whole bear. After looking at the information more closely 30 years ago, researchers now have stronger evidence that such an ocean is actually available.

A team led by Corey J. Cochrane, the planetary interior and geophysical team in NASA’s JPL, did not start looking for an ocean in Callisto. According to Cochrane, he worked on the team a different projectattract To scan the Neptune Month Triton to see if there is an underground ocean.

This was a problem for the dense ionosphere of Triton, the last layer of the atmosphere before the start of the empty spot. Because Caliston has an intense ionosphere, the team decided to test the methods of NASA’s Galileo mission on 30-year-old measurements. In 1989, this mission has launched and scanned Jupiter and his months between 1995 and 2003.

“Our results analyzed the measurements taken at a fly of Callisto, in general,” noise “in society, the” noise “, which belongs to the plasma environment, he informed CNET in an e-mail.

“We were able to use the previously made plasma simulations to delete this dark plasma source of noise, so he said,” Coxrane “to be analyzed independently.

In short, Galileo readings were first difficult to comment on the powerful ionosphere of Calliston. COCHRANE and team were able to review the information, after cleaning the readings, and it shows that the month is an ocean under the rocky appearance.

Ionosphere looks like an ocean

A strong ionosphere is imitating readings if a strong ionosphere is so long to prove the existence of an underground ocean in Callisto.

“The main physical law of nature (magnetic induction law) will prepare an electric current that synchronizes the magnet’s action, as a magnet wire,” Jangran said. “This current will create a magnetic field that demonstrates the characteristics of a conductive material, called (in wire electrons), conducted magnetic field, and the properties of the conductive material.”

Cochrane said that this work is also working with the planet bodies. The moon or planets with internal heat can be the ocean of liquid salted water under the surface. These oceans are conducting electricity thanks to the salt in water. Thus, scientists can use magnetometers to measure the magnetic field, “It protected the features of the ocean”, “Coxrane said. In other words, he can be found based on the magnetic fields that create oceans.

Jupiter’s Callisto and Neptun’s Triton is very powerful, readings with a magnet gauge, the researchers have difficulty understanding that there is only a random noise in an ocean or ionosphere. Therefore, researchers have been stuck in the potential underground ocean of Calliston for decades.

Next steps

Science will not have to wait for another 30 years to find evidence. NASA’s European Clipper Mission Sailing Last year and in 2030 Jupiter and his months, European Space Agency Juice mission Should come in 2031. Both missions will provide more research data for almost callisto.

In terms of data related to the collection, Cochrane said that this does not necessarily know. On the contrary, there is more information.

“Prove the presence of Callisto’s new measurements, it is more to have more measurements to make a simply analyzed,” Coxrane said. “For each fly that occurs for each of these missions, the magnetic field environment is only caught by a very small image magnetometer.”

Cochrane will help the data from the Galileo mission from the European scissors and juice missions, hopefully researchers finally prove to prove that an ocean is in the callisto of the ocean. Additional information will help the researchers assess how thick calliston’s ocean layer, as well as the thickness of the ice crust.

Could it be life in Callisto?

NASA and the European Space Agency would not send tasks to Jupiter without good reasons to do so. One is: Europa’s hidden waters are front for surface life.

“It is possible to support the life of the Europa Ocean, because it is a long enough life for life, water, necessary chemical elements and energy (for example, the source of heat),” he said. “Europa Clipper will actually submit the information required to help you better help to answer this question.

But in Callisto there is a business growing for life. Have A surprising amount of oxygenAnd no one can understand where it comes from most. Although an underground is the possibility of an underground and still is still, Jupiter is quite evidence to look closely to MY when it comes to 2030 and 2031.
