Scientists believe that there is a huge ocean on Jupiter's moon Io, but not at all from water.
None of the known satellites of planets in the solar system compares to Jupiter's third largest moon, Io. This is the most volcanic world on which there are several hundred active volcanoes. Scientists believe that something unusual must be hiding under its surface, writes the Daily Beast.

Scientists Yoshinori Miyazaki and David Stevenson from the California Institute of Technology, USA, believe that under the entire surface of Io lies a huge ocean of magma.
According to scientists, this very hot layer of molten rock on the moon of Jupiter with a diameter of 3500 km, may be a unique formation for the worlds of the solar system. This ocean may hold the secrets of how satellites and planets form, and even harbor exotic alien life.
Scientists have long argued about what lies under Io's crust, which is about 20 km thick. As part of a new study, scientists again analyzed data from the Galileo spacecraft, which completed its work in 2003. Some scientists have already suggested that Io has either an underground magma ocean or some kind of spongy, rocky outer mantle saturated with magma.
< p>But Miyazaki and Stevenson came to the conclusion that there is an ocean of molten rock. They believe that in the upper part of Io's mantle, the temperature can reach more than 1500 degrees Celsius.
“The amount of internal heat of Io is not enough to maintain a high degree of melting of the rock. So there is still an ocean of magma under the surface, which is supported by eruptions volcanoes and rotation in a very elongated orbit around Jupiter,” scientists say.
Miyazaki said that the Juno spacecraft will explore Io in 2023 and 2024 and will be able to confirm the scientists' assumptions.
“I don't think this discovery will change our understanding of planetary formation much, but it does change our view of internal structure and thermal evolution of bodies like Io,” says David Grinspoon of the Planetary Science Institute, Arizona, USA.
“on Venus, and on Saturn's moon Enceladus. Theoretically, there could be life on Io. But there are too many volcanoes, so if life develops there, it's probably a very strange life that really loves heat,” says Miyazaki.
As Focus already wrote, scientists have discovered a mysterious phenomenon on Io and perhaps this satellite of Jupiter is similar to one of the planets, which is described in the books from the series “Dune”.
As for the spacecraft “Juno”, as Focus already wrote, he made new amazing pictures of the atmosphere of Jupiter.
