Europa’s oceans are silent.

Jupiter’s  Europa-moon oceans can be dead. So, new research suggests. That there are no lifeforms under that moon’s icy surface. When we think about Europa’s oceans. The Europa moon's oceans. They are not like oceans on Earth. Those oceans remain liquid because the gravity of that moon is very weak. Jupiter’s gravity causes powerful tidal waves. Under. Icy shell of that interesting moon. This tidal force causes the water whirl around that moon’s core. 

"A new study led by Paul Byrne, an associate professor of Earth, environmental, and planetary sciences, raises doubts about whether Europa’s ocean could support life at its base. By analyzing the moon’s size, the composition of its rocky interior, and the gravitational pull it experiences from Jupiter, the research team found little evidence that Europa has the kind of active geology thought to be essential for life. Their results suggest the moon lacks tectonic movement, hydrothermal vents, and other forms of underwater activity that could supply energy to living systems."

And this thing makes the magnetic field for that moon. The magnetic field. Denies cosmic radiation and radiation that comes from Jupiter’s plasma ring from destroying water molecules on the Europa moon. Europa is the icy water moon. This means that magma, which is the liquid rock under Earth’s shell, is replaced by water in Europa. 

Magnetic field. Forms when the magnetic mineral dust in the water spins around the core of that moon. So, can there be lifeforms in that moon’s ocean? The thing is that there are no things like fish. The creatures that researchers may hope to find are primitive bacteria-type organisms. If those organisms exist, their metabolism will be very slow. 

There is a possibility that those organisms can synthesize oxygen from water. Using electrolysis, which can form when the noble and base metals are near each other. This electrolysis might not be very effective. But if there are no beasts in that ocean, that can be enough for those organisms to maintain their processes. Those things are only guesses. But the thing is that. This moon can also be dead and cold. But the thing is that Europa itself is interesting. That moon can tell. About conditions. What is on icy planets, and why can those planets that can be giant ice giants exist? 

There may be no geothermal energy in Europa. This means that the core of that moon. It can be. A very small. Thing. Without radioactive material. And the energy that keeps the oceans liquid forms when tidal forces and the cryovolcanos cooperate. The cryovolcano forms low pressure. Under the moon’s icy shell, that weak gravity keeps water molecules separate. The tidal forces. Puts those molecules in motion, in the weak gravity. Because of. In weak gravity, water can be liquid in far lower temperatures than on Earth. If there are lifeforms, those lifeforms can hover in the freezing water rather than be on the bottom of the moon. 

We can determine life as a self-replicating structure. Those structures can react and interact with each other. The fact is. Nobody knows what organisms on other planets or moons look like. Some models suggest that. On very low-temperature moons or planets, DNA can create ice bites. These are DNA-controlled. There is a model. That alien organisms can be water ice. And theoretically. The nanobubbles can form a similar structure to the DNA. Those things cannot be stable on Earth. But. In very low-energy, stable conditions, it is possible that the self-replicating structures can exist.
