The strange moon of Jupiter continues to amaze scientists 400 years after its discovery

Many of you are well aware thatThe large planet of our solar system has a huge retinue of 75 moon moons, each of which may be interesting in its own way for research. The most striking and famous among all the moons of Jupiter are the so-called Galilean satellites: Ganymede, Callisto, Europe and Io, which were discovered in 1610 by the famous astronomer of the Middle Ages Galileo Galilei. The strangest and least explored satellite among them is Io, whose surface is literally dotted with constantly erupting volcanoes. 400 years after its discovery, this moon of Jupiter still does not want to part with its secrets.

Io’s surface is very reminiscent of the work of some impressionist artist

What does Io look like?

About 40 years ago, the Voyager space probe,exploring the vicinity of Jupiter, for the first time took photographs of the bright yellow surface of one of the moons of the giant planet Io. Even then it was clear that this unusual moon is a geologically active satellite, the surface of which is constantly changing due to incessant volcanic eruptions on it, the dimensions of which are sometimes several times the length of the Earth’s highest mountain - Everest. In addition, it was the “Voyager” who managed to “see” the radiation belt of Jupiter for the first time, which just along the orbit of Io. It is because of such an unfortunate location that the radiation power of a giant planet on its nearest satellite is 1000 times stronger than radiation on the Earth’s surface, which makes a person’s presence on Io deadly. In addition to radiation, Io is famous for its high sulfur content, which gives it the famous bright yellow hue.

Mysterious activity on Io puzzled scientists

According to the portal Space Daily, scientists fromCalifornia was able to establish that the huge number of volcanic eruptions on the satellite of the giant planet does not obey any generally recognized models of volcanic activity.

Researchers came to this conclusion afterobservations of active volcanoes of Io, which theoretically should arise symmetrically at the equator of the satellite or its poles. However, the explosive satellite of Jupiter surprised scientists with many short eruptions that arose on the opposite side of the satellite. Powerful pulses appeared suddenly and lasted several days, which completely contradicts the physics of tidal heating. This effect allowed scientists to believe that in addition to the powerful gravitational influence of Jupiter, Io also has its own source of volcanism, which makes this moon the most volcanically active body in the solar system.

In addition, scientists were able to come to a veryan unusual conclusion: volcanoes on Io can mysteriously shift and occur in other places of the satellite. Studies have shown that the underground magma oceans of this satellite of Jupiter, which constantly update the surface of this bright yellow moon, may be the fault.

Perhaps it would be very interesting to see such a phenomenon with my own eyes. Although, probably, this would be the last thing that could be seen during his short life on radiation Io.
