IO’s mysterious interior works, Jupiter’s volcanic moon

It is important, unlike the strange magnetic field of IO, which seemed to indicate that it has concealed the value of the liquid in the ocean, the magnetic signal in the Galileo era in Europe remains strong. “It is a clean result in Europe,” he said Robert BabalardoEUROPA project world in the jetpacker laboratory. Ice satellite is far away from Jupiter and the intense space environment in the plasma in IO that the EUROPA magnetic definition is really clinging to.

But if both satellites are heated civil, then why does Europe only have an internal environment? According to Nimmo, “There is an essential difference between the circumference of liquid water and the surrounding of the magma. The magma wants to escape; the water does not do it.” Little liquid rocks are less dense than solid rocks, so you want to rise and explode quickly; The new study indicates that it does not remain in a long deep depth inside IO to form a huge interconnected environment. But liquid water, unusually, is more intense than its solid ice shape. “The liquid water is heavy, so it is gathered in the vicinity.”

“I think this is the big message of this paper,” a Syrian added. Tin and islands may fight to create magma’s oceans. But on ice moons, it can easily make water oceans due to a strange decrease in ice density. This indicates that life has many environments that can be valid for housing throughout the solar system to connect to the home.

The revelation that IO lacks the vicinity of shallow magma emphasizes the lack of heating the tide. “We have never understood the place of melting the scarf in the inner part of IO, and how the melting of the scarf reaches the surface,” said De Kller.

Our moon shows evidence of the essence of the primitive tidal as well. Its oldest crystals were formed 4.51 billion years before the molten material stream that was detonated from the ground by a The giant effect occurred. But it seems that many moon crystals have been formed from a second tank of molten rocks 4.35 billion years ago. Where did the magma come from later?

Nimmo and Coauthors view one idea in paper It was published in nature in December: Perhaps the Earth’s Earth Moon was like IO. The moon was closer to the Earth at the time, and the gravitational fields than the earth and the sun were fighting for control. On a certain threshold, when the gravitational effect of both of them was almost equal, the moon may have temporarily adopted an oval orbit and heated it in a way. It may be inside it, causing a sudden secondary prosperity for volcanoes.

But exactly where the tidal heating was concentrated inside the moon – and therefore, as all this melting was happening – it is not clear.

Perhaps if IO can be understood, we can also our moon – as well as many other satellites in our solar system with hidden tidal engines. Currently, this volcanic cyan body is still mysterious. Davis said: “IO is a complex monster.” “The more we notice, the more data and analyzes develop, the more confused.”
